Hey Guys,
After shooting my rife at 100yds, I can't get my rifle to group under 3". Not ok. It honestly isn't me I handed the rifle off to a friend of mine who is a MUCH better and far more experienced shooter than myself. He got the same results. The rifle is: RRA LAR-15 lower RRA LPK RRA 6 M4 stock FN carry handle Stag Arms 2H upper (16" chrome lined 1/9 twist) A2 Hider Ammo: 55gr Hornady FMJ Lake City Brass 21.7 gr of H335 CCI No. 400 Primers Thanks Guys, Bob |
Frankly, 21.7 gr's of H335 is a fairly light load. I get my best accuracy in 5.56 using 25.0 to 25.5 gr's of H335. 25.0 gr'd. seems to be the most popular choice with H335 because it is fairly close to what you'll get from factory ammo. You might experiment some with some heavier loads than what you've been using. It might be the ammo and not the rifle or the shooter. Don't be surprised if the POI changes with different loads.

Quoted:
with a scope you'll only get 2 moa out of a carbine chrome lined barrel. 3 moa is good for irons. and 4-5 moa is good if you're using a red dot. nothing wrong with the gun. but you should at least get 1 moa at 50 yards at the minimum umm.. not true. This is at 200 yards.. with 1/7 and 16" CL HF upper.. with the 6x32 cheap scope from a front BAG only.. 
I would say irons is 4-5" and with Red Dot is like 3-4".. at least thats what I get.. heres my 3MOA red dot on my old 1/9 DPMS upper from the same front BAG only..
