I’m building my first AR15. I don’t have an assault rifle right now, so this build needs to be decent at everything. I ordered a Daniel Defense(DD) upper with a 16" 1in7 government profile CHF barrel, midlength gas system, low profile gas block, DD lite 14" free float quad rail, YHM 5C2 compensator/flash hider, and DD BCM and charging handle. I also ordered a DD stripped lower, Bill springfield LPK with 4lb trigger, Magpul MIAD grip, ACS milspec stock, Milspec buffer tube kit, Enhanced trigger guard, 3 Pmags with ranger plates, MBUS front and rear, AFG1, B.A.D lever, Ladder rail covers, Tacstrap 1/2 point sling, and slap plate, 1000 rounds of fiocchi 55 grain, and 120 rounds of hornady 75gn match. I haven’t decided what to run for an optic yet. This will be primarily used for practical rifle, and also be my SHTF gun. Once I get it put together and assembled I’ll get it to the range and see what it’ll do. If it won’t do MOA then I may swap the barrel out for a WOA 18" midlength SPR barrel, or something similar.
Looks like a good build.
Between you and the rifle, 1 MOA will probably be the best you could hope for…so don’t be disappointed…it’s perfectly acceptable for a “battle” rifle.
Looks like you did your research…
Sounds like a great first rifle! Any reason why you went with the 14" rail over a 12"?
Well, it looks cool, increases site radius, in the future I may go with an 18" barrel, and it was the same price no matter what length rail I chose, but is worth more if I decide to sell it later. And being a big guy I’m not that worried about a few extra ounces.
If your going with an 18" barrel it should be fine. But, anything over 12" on a 16/14.5" barrel tends to be very front heavy.
Hey, if it works for you, do it.
I can’t see anything there to criticize.
Wouldn’t the balance (front or rear bias) depend on the stock and optic also?

That’s another reason I went with the ACS stock. I can always put some ballast in the battery compartments to help shift the center of gravity rearward.
Why 55gr? 1/7 twist tends not to like rounds that are below 60gr.
Did you read that on the internet? 55gr. ammo works fine in most every 1/7 rifle. For example- my 11.5" SBR will hit steel plates consistently at 300 yards.
I also recently used 55gr. TAP ammo in the same gun in a Patrol Rifle Course and had no issues punching steel and plates out to 100 yards.
What is your experience with the AR? I think that you should look at the weapon as a SHTF weapon first and a “practical” rifle second. Or build it strictly as a practical gun.
I would also lose the the B.A.D lever unless you have mastered the basic operation techniques first.
Is there a reason why you need it to shoot 1 MOA? I seriously doubt any off the shelf standard barrel will shoot 1 MOA. My Noveske Recon shoots about 1.25 MOA and it isn’t off the shelf.
That’s a good idea! I have the 12" RIS II with a MOE stock and its a bit front heavy but that would solve the problem.
I learn something new everyday on this fabulous website.
Yes it would. I made the mistake of not taking the stock and optic weight into account at the time. My bad…
It might of been my imagination, but I’m pretty sure I read somewhere about a centurion arms 16" barrel being 1 moa. But, I could be wrong. (Like I usually am :D)
Double post…
triple post…
From what I’ve read. The 1in7 twist is great for the heavier 223 bullets.
It’s primarily a shtf gun. But practical rifle looks like fun and since I don’t plan on being competitive. It’ll work fine.
I don’t have any real world experience. And the bad lever sounded like a good idea. But untill I try it I won’t know.
It doesn’t have to shoot 1 moa. But I’d like to be able to make hits at 500 yards and the more accurate the rifle, the more easily that would be.
It is good for the heaver bullets but it works perfectly fine with 55 grain bullets as well.
That’s what I’ve heard, and why I bought 1000 55 grain to practice with. And 120 75 grain match rounds for 200 yards plus.
Id save those 75 grain bullets for distances a bit farther than 200 yards…
