my 1st build! Noveske/Vltor/Centurion/RubberCity/Geissele

Following the tragedy at Sandy Hook elementary I, like many other firearm enthusiasts & connoisseurs, found myself swept up in the inevitable hysteria. Prior to beginning this build, my experience with firearms was based solely on handguns. I had always wanted an AR-15, but seeing that I was a full-time student I was unable to afford the upper echelon rifle that I really really wanted. These circumstances were only exacerbated by the post-Sandy Hook frenzy. For example; while perusing my local gun shop I saw a new FDE Sig M400 marked up to $2,500…and quickly realized that I would be unable to afford the kind of rifle that I wanted. I would have been more than happy with a 6920 but at the Crossroads gunshow they were marked up equally high. I began considering building my own, which would allow me to eventually own a rifle exactly the way I wanted it while also tackling the process as slow or as fast as my wallet would allow.

This rifle is the fruit of that labor. I finished it just about 3 weeks ago, in total taking me over a year to complete (with a 5 or 6 month break in the middle due to a string of car issues that required financial attention). When I began researching parts & envisioning the rifle, I saw it as an overly expensive & high-tech weapon with a piston operating system, stainless steel barrel fluted out the ass, a hydraulic buffer & ambi-everything (just cus) w/a 15" quad rail & a Spikes Tactical mock suppressor. OK I’m just joking about the mock suppressor but as I began my research I really wanted all those others types of components. But as I continued with months & months of thorough research and began realistically considering my needs, abilities, & priorities, my rifle quickly took on an entirely different role & image. As such, my desire for this rifle was to have a reliable & dependable tool made of quality (if not top-tier) components that would serve as a capable AR-15 on which to learn the fundamentals of rifle marksmanship & with a service life of 10’s of 1,000’s of rounds. I would love to someday teach my son to shoot with this rifle.


Lower Receiver: Noveske Gen 2 (Chainsaw)
The 1st component that I purchased. At the time I had never heard of Noveske and chose it primarily because I liked the logo, it’s unique aesthetics, & the little chainsaw icon. I picked it up on gunbroker…so yeah I had to pay a little extra forsure.

Upper Receiver: Noveske/Vltor MUR (Chainsaw)
The 2nd part purchased. After buying the lower I ofcourse looked up Noveske and quickly realized how awesome a company they are. At the time they had stripped MUR uppers on their website and I was monitoring daily the sold out status. When they abruptly decided to no longer sell them directly I hopped on gunbroker and picked one up. I wanted the Noveske version purely for continuity’s sake all the while knowing that depending on the rail I chose the Vltor version may have been necessary…however pickings were somewhat slim and I decided to jump on the Noveske MUR while I could. The gentleman who sold it to me was also selling a brand new stripped LaRue upper receiver that even now I wish I had bought.

BCG: Rubber City Armory
Originally, for no real educated reason, I had wanted a Fail Zero NiB BCG. I had read a lot of hype and quickly decided that it was the superior bolt & carrier. However, BCG’s were a hot commodity during the panic and the wait time was quite long. One day I stumbled upon RCA’s website and saw that within the next couple weeks they would be putting up a bunch of BCG’s. I picked one up largely out of convenience. They were ~$250 back then, had the forged gas key, and a non-nitrided firing pin.

Barrel: Centurion Arms 5.56 CHF & chrome lined 16" mid-weight
I undoubtedly spent the most amount of time researching all kinds of barrel-related topics, and really making sure that I would happy with the one I would ultimately choose. As I said earlier, I originally wanted a stainless & fluted “look at me” barrel. I looked into BlackHoleWeaponry, Legion, WilsonCombat, etc. However, as I continued deeper into my barrel studies, I began realizing that at my skill level and with my intended use and service life & performance desires, I would be better served by a high quality carbon steel barrel. I 1st impulsively purchased a 16" socom profile melonite barrel from AR Performance. While it was very well made and I liked its .223 Wylde chamber, it was a little heavier than I liked and the fact that it was threaded 3/8x24 made muzzle device selection kind of annoying. I decided to sell it and put it towards the Centurion (which I couldn’t be happier with).

Trigger: Geissele Super Tricon
I originally wanted a skeletonized Timney, mainly because I thought it looked really cool (which it does) and because they’re local to me. However I decided that I didn’t want a precision-based trigger. I’d heard & read so much about Geissele that I couldn’t pass up on trying one. The fact that the Super T is essentially an SSA with a unique trigger bow made me comfortable in that it’s not (for me) un safely high speed.

Handguard: Noveske NSR-15
I originally wanted a 12 or 14" DD Lite or RIS II. However after picking up a Noveske Gen 2 upper & lower my attention was understandably drawn towards the NSR. The benefits of keymod as well as the long & thin design were immediately apparent to me. The anti-rotation interface between the MUR & NSR is also a nice bonus. I can’t say enough how much I love this handguard.

Muzzle Device: Battlecomp 2.0
Choosing a muzzle device proved difficult due to the extreme over abundance of options out there. For years I had wanted a Surefire break on my 1st AR. However at the time I would shoot my handguns solely at the most local indoor range and I was unsure how often I would be shooting my AR inside so I decided against a dedicated muzzle break. I decided on the Battlecomp due to it’s proven track record and also because it wouldn’t add a comparably large amount of length to the rifle. It works well.

Gas Block: Vltor 0.75" set screw, black
I chose the Vltor gas block for a couple reasons. The first is that I had planned on using a few Vltor products (upper & buffer system) so their gas block seemed a sensible addition. Secondly, while I assembled the lower by myself, the upper I had professionally assembled by a Rainier Arms. I had them do it largely because I wanted the gas block pinned and I wasn’t comfortable putting a drill to the $300+ barrel, and also because the lifetime warranty they offer on their labor gives me peace of mind. I knew they would be able to pin a Vltor gas block.

Safety Selector: BAD-CASS
The safety selector is the only ambidextrous component that I used. I did this because I wasn’t sure whether I would prefer returning it to safe with my thumb or index finger. I’m glad I did this because it turns out I do prefer using my index finger to actuate the lever back to safe. I chose the regular length/thickness lever thumb side and the short length/regular thickness lever opposite side. And if you’re getting a BattleArmsDevelopment selector why not get the combat version w/the dovetails?

Buffer System: Vltor A5 receiver extension w/H2 buffer weight & Sprinco ‘green’ spring
While I had originally wanted either a hydraulic buffer weight or JP’s captured system, I ultimately chose the A5 system largely because I was convinced by its enthusiastic following. And when comparing the A5 system to the rifle length system it really makes perfect sense.

BUIS: Troy w/M4 tritium front & DOA rear
I looked at a lot of back-up irons before ultimately deciding on Troys. It’ll be a big day when I get together enough cash to buy a quality optic, until then I have more research to do on the topic & I’ll be shooting through by irons. So seeing as I planned on becoming well versed on shooting through open sights I wanted a quality pair. The Troys are strong & robust and well proven. The HK front with its front sight post sitting either low or high in a circle doesn’t make sense to me so M4 front it was. And the idea behind the di-optic aperture seems sound so I decided to give it a try. I had originally wanted tritium in both front & rear but having a glowing blur right in front of my face didn’t seem too necessary when I feel all you really need is the glow in the front…if it’s true for handguns then it should prove true for rifles yeah?


LPK: Colt
When searching for the best LPK’s, the lists I found always seemed to be topped by Colt. Seeing as they’re one of 2 or 3 companies (if not the only company) to have the TDP this would make sense. Also I like having colt represented somewhere. I purchased the kit from SpecializedArmament so yeah I had to pay a lot but they’re in my state so that made me feel maybe a little better about it.

other parts that don’t require explanation:

Noveske branded Vltor/BCM charging handle
WMD nitromet mid-length gas tube
Colt castle nut (from Brownell’s because SpecializedArmament has a $45 minimum order policy)
Magpul ASAP (for whatever reason QD attachments seem like they could fail…I know many people use them with success in harsh conditions but still…to each his own I guess)
Magpul CTR w/enhanced buttpad (almost got the Emod & still kind of want to try it)
Magpul MIAD 1.1

I’d like to wrap up by saying thank you to M4carbine.net and the entire community on this fantastic forum. This site has proven to be the most valuable tool when researching & studying all aspects of the M-16/AR-15. I am constantly humbled by how much there is to learn and by the large number of experienced individuals from whom to learn it. It’s safe to say that my rifle would not be the capable & mature tool that it is if it was not for the wise guidance of M4carbine.net. So once again, thank you all so much! Oh and a big thank you to the manufacturers, retailers, and individuals from whom I purchased! Thank you all for doing what you do the way that you do it! See you at the range!

Great post OP and very nice rifle. Let us know how she shoots.

Gear Scout has a write up on that rear sight. It has a few issues. Mainly don’t drop it, it will not take much of a hit without sustaining damage. You will find the front sight post will be to wide and cover most small targets even at closer distances.

Over all great write up. Thx for including the pics.

For the record, THIS is how to use the internet to research firearm purchases - it’s encouraging to see where your starting point was conceptually with a lot of the components, and how through reading you’ve wound up with something vastly better.

It’s a great looking build that you’ve put a lot of thought into. Out of curiosity do you intend to add a magnified optic or red-dot sight? What about a weapon-light? Have you made a choice on your sling?

wow, nice post! It’s great to see people like you around; researching and buying quality rather than making a mistake with a Bushmaster or DPMS int he first place like so many people do.

Nice rifle!

This is the best thought out first build I’ve seen here so far. I know nothing about the BCG so can’t comment. So the only part that would have to go for me is the rear BUIS. I tried that and the white lines seemed distracting. Oh, and the enhanced buttpad which I don’t think justifies the weight, especially with the A5 system. I went the buy thrice, cry thrice route before ending up with a build as sweet as this one. Well done.

Great post. Excellent barrel choice, I’ve had fantastic results from Centurion barrels, like Recon level results. Enjoy

Is that up at Ben Avery?

Thanks man. She shoots great! It was my first time zeroing a rifle so it took me a couple trips to the range before I felt confident with my 50 yard zero. But shooting this thing is so much fun! It’s kind of ridiculous how much fun it is to dump a magazine through it. And I’ve just taken a closer look at the rear sight and the large aperture does stick up just a little higher than the protective “wings”(?) on each side…so yeah I can see how if it took a direct hit it wouldn’t fare too well. What did you mean when you said the front sight post will be to wide? Because of the tritium vial it is long down the side but the post itself turns independently so you can orient the vial towards yourself after raising or lowering the elevation…idk if that’s what you’re referring to…or if the non-tritium version really is just thinner from the front…

Thanks man!

Thanks man. So I’m a ways away from being able to get an optic…but for awhile I was set on first getting like an aimpoint T1 or comp M3 (although now the PRO seems more realistic financially). However, as I think about it more I’m most likely gonna be getting like a 1-4 or possibly a 1-6…an ACOG w/the RMR would be awesome too if i can swing it. As far as weapon lights go, Surefire scout light for sure; mini scout or ultra scout. And I’ve actually spent a lot of time considering slings. I realized that I really like the magpul with the 2 to single point function…I just really wanted it to have some padding. So I’ve ordered a padded vickers vcas and a magpul ms3 and I’m gonna be mixing and matching different parts of each to get a single sling exactly the way I want it. I’ll post it up here somewhere when it’s set up.

Thanks man!

Thanks man. Yeah the DOA rear definitely isn’t for everyone…when I bought it I thought the lines would help position the front sight post but after shooting it a couple time I’m not so sure. And to be honest, the enhanced buttpad I really thought just looked cool. Originally I was set on either the Vltor Emod or the Magpul STR, but ended up going with the CTR cus it was cheaper (although the enhanced buttpad raised the price to where I didn’t really save much money at all…kinda poorly thought out). As time goes on I really wish I’d picked up the Emod.

Thanks man. Yeah deciding on a barrel was a long process for sure and although it’s early I’m really happy with it so far. I almost picked up a Noveske/FN barrel last minute but I realized I was only gonna be getting it to have another iron cross on the gun, and in the end I like how the Centurion doesn’t have the increasingly popular weight-saving profile. I like knowing that it’s gonna be around & kicking for a very long time. If you don’t mind me asking, what Centurion barrels have you had or shot? I’m really curious about their stainless recce. But I’ve noticed that there aren’t as many of their barrels for sale online as there used to be, and their website has been down for awhile…

That’s at Rio Salado Sportsman’s Club up on Usery Pass on the far NE edge of Mesa. It’s similar to Ben Avery in that (if I remember correctly) the land or range itself is owned by AZ fish & game. Ben Avery’s a lot bigger though I think.

Excellent first build! Excellent write up! The BCG is the only thing I’d question, but every product has to start somewhere and if this one does the job, rock on. Now, Get a sling, some spare parts, and more ammo. Shoot the hell out of it and let us know how she does.

BEAUTIFUL! I would say NOT Only is this a good 1st build as some have put it… I think It’s an Awesome Build even IF you’ve made 50 of these Bad Boys! LOL
Great Write up with details and pictures, sweet job all around mang.,:wink:

I do have 1 question, ONLY because it does NOT Look like you got the Correct part>> “Fail Zero NiB BCG” << You should check that,… And FWIW: That thing IS AWESOME, I am so glad I got my Fail Zero BCG, worth every single dollar!

Peace Jeff

PS> About the Front Sight, I believe “SpankMonkey” was talking about how Wide-Thick thatFront Post is, that bad boy looks like it’s 3mm wide! In the pictures anyhow…?LOL

Thanks! I’ll address the bolt carrier group in the below response. Oh but I’m gonna be picking up a spare BCG very soon & I already have the spare fire control group from the Colt LPK so at least it’s quality mil-spec. And I have two slings on order that should arrive very soon…I’ll be using parts from both to make what I think will be the perfect sling. I’ll post it up here when I finish it.

Thank man! I didn’t mean to say that the Fail Zero isn’t a good (or great) BCG, only that I was too quick to think that NiB is the end-all-be-all premium weapon coating. The RCA bolt & carrier is just as high quality…it’s black nitride (done very well btw) is a treatment that affects the metal itself as opposed to NiB which is a coating which could possibly chip and/or flake. Both provide the same benefits. In fact, Noveske a few months back was selling RCA BCG’s w/their iron cross logo that of course were marked up like $50 or so…however they’re no longer listed on their website so they must have just sold them for a little while.
