So i have recently gotten the urge to build myself an ar15 from scratch and have been doing research and know basically all the parts i want to buy but then upon more research on the actually building part it was said that it is difficult to do and at that to get it to look good…is this true?
Actually the the exact opposite is true. Building/assembling an AR is not terribly hard to do for someone that possesses reasonable skill and patience - what’s really hard is the research, research, research and buying quality components that work well together. And not rebuying parts again down the road because not enough research went in to buying the original parts in the first place. Take your time and be sure you want to build and want to invest the time.
I would say buying a complete AR also takes plenty of research, you just can’t avoid it.
ETA: What parts have you decided on buying?
BCM FA BCG
BCM charging handle
BCM Buffer tube
14.5" lmt or daniel defense barrel
stripped upper and lower just vary on what i can get for a decent price, probably a spikes lower though. I would really love to get a black rain upper and lower though :laugh:
KX3 Flash Suppressor
RRA lower parts kit
daniel defense or a LaRue rail system
I am not worried about furniture and sights at the moment
Anyone with some mechanical skills can build an ar-15, I think you’ll find it’s easier than you think, and much more gratifying to build your own, but yes you must do your homework, and remember depending on what rail system you want to use may depend on what barrel nut/system you need to use.
Check out this link; I think it will at least give you an idea of what is involved, and the tools you will need to compete the job…

Good luck with your build and let us know how it turns out.
Im thinking i will probably go with the dd omega x rail which is what i have on my other ar and i love the fact that its weightless. If i remember correctly those come with the barrel nut. Also the fact that i get a discount at DD helps too. so thats most likely where my barrel will come from also
Yes, the DD Omega X rail uses their proprietary barrel nut.
Well then when you order the rail and barrel have DD slip on the barrel nut before assembly of the front sight post/gas block before they send it to you, or when you get it you will have to remove the front sight post/or gas block and flash hider to put the barrel nut on, unless you are just going to order the barrel stripped and install the gas block yourself, but I would just have DD do it that way it will be properly pinned…(just things to think about)
Oh yea, and what about this discount from DD that you get…
How can I get one!!!:sarcastic:
With your 14.5 barrel you will need the KX3 to be pinned and welded, otherwise you’re in NFA territory. The KX3 will also negate weight savings with the Omega X—KX3s are best suited for 7.5-12.5" weapons to help with cycling issues that may arise. Make sure the BCM buffer tube is also Milspec diameter—more stock options later if u want them.
It’s not that difficult to build, but what you lose out on is a lifetime warranty from most quality manufactures. To me there’s not much value in that…
You get a discount by signing a few years of your life to the United States governement 
and yea i just figured that out about the barrel…so what i was also thinking because im going for the short barreled look iw as thinking of getting a 16" barrel and getting a barrel shroud… if that would work? Also what would be a reasonable price for a matching stripped lower and receiver. I looked at the black rain set and its $500 for both and that seems way steep for just stripped receivers
An aero precision matched upper/lower will cost no more than $200. I actually paid $79 for my lower and $59 for the upper, but seen them for more in brick and mortar stores. BTW; these guys make the receives for some of the big names–the only difference is the logo.
Ive seen those aroundbut wasnt sure of the quality of them. Ill have to check those out now. Also why is it impossibel to find a spikes upper? i found a lower on their site for 99 dollars and then they have the matched upper and lower ont ehir site for 500 dollars…a $400 dollar upper!!!
I should have mentioned–I built two AR’s with AP and the fit & finish were great.
Plenty of info on them: here’s a closeup pic.

Also–they make lower’s for the AR-10 too and just as good. Ask me how I know!
How do you know?
So im at the danieldefense website and what is all the different barrel profiles. What is the determining differences between them all?
I prefer to build my lowers and buy my uppers and here’s my rationale.
The lower is my primary interface with my rifle and I prefer to pick LPK, grip and controls. I’ve got a bunch of spare hammers, triggers and disconnectors laying around that I’ve polished up a bit and find the parts that give me the best trigger feel. I’ve actually had great results with my the triggers I’ve got from them in the past. I’ve found that a good mil spec trigger is every bit as good and probably more reliable than most aftermarket triggers. Check out G&R tactical, you can pick and choose your lower part kits and the parts are outstanding.
An upper is the primary determinant of accuracy and reliability and there’s a lot of companies that can put one together better than I can at a lower price. You can dick around with handguards, sights and optics and make it feel custom and get the reliability of a properly assembled upper. I’ve relied on machinists/gunsmiths for gas block pinning and gas tube alignment and checking headspacing as well final inspection so I don’t get blowed up.
There’s only three real profiles in regards to their barrels say in the 16’ middy length; M4, government profile and light weight.
The only difference between the M4 and the Gov is the notch in the M4 to accept a grenade/flare launcher. The other is self explanatory–lighter weight.
You should also take a look at Centurion Arm Barrels.
so what you are saying is that i should build my lower and buy my upper factory new and add/remove rails,sights etc to my liking?
if you have the simple tools, its easy to build a lower. However the upper require more equipment and isnt as viable to build. If you want a freefloat rail, you can get them pre installed with the upper from places like Bravo Company. Otherwise they will require gunsmithing tools.
Hmm ok…ill probably do it that way then…as to avoid injury of noob skills. Also does anyone know if g and r tactical offers military discounts?
