Try some heavier ammo. If I'm not mistaken that rifle comes with a 3/4 MOA guarantee.

so its grouping about 2.75

May not be the load your gun likes

In my NM A2 upper I've had great luck with 52SMK screamer rounds (27 grn RL-15) and 77SMK rounds but didn't shoot groups with those today.

The factory Hornady 55 is showing a typical group, same thing I've seen in my A2 upper

I agree with trying some different ammo. Something heavier probably, or some handloads with Hornady V-Max/A-Max bullets.

If you're shooting for groups I'd ditch the bipod temporarily and use a proper rest and rear bag.

I'm curious if you like the scope where it's mounted? I have the same scope on a Colt HBAR and have it mounted about an inch farther back. Seems like I need to move my head too far forward otherwise.

I hope i downloaded this target right. This is mine at 300 yards and iron sights off a sand bag. 5" red dot target. Same rifle as yours. I bought the day after Obama was elected.
55 gran South Korean NATO ammo. My son took the picture, i know it isn't focused well. I don't reload. 60 rounds fired last month, 36 degress out no wind.

So, 300-15X?

Go out and kill bad guys like a champion.

Not sure if you reload or not, but try some 75gr Hornady BTHP's and 77gr SMK's over 24gr Varget and see what a drastic improvement you see. I have to tell you to work up to that load, however most will tell you its spot on for their 1/7 or 1/8 barreled rifles.

Mine Loved the Parvi 75 gr match stuff. It would shoot under 1" at 100 all day. I had a Simmons 6.5x20 scope mounted on top of the
A2 carry handle. I used it to shoot coyotes out to 400 yards and steel out to 500 yards.
I kind of miss selling it just for the fact it was SOOO dam accurate.

I ran some statistics on my RRA 16" 1:8 barrel with different loads.

40gr VMax was the worst
55gr Hornady FMJ got better
60gr VMax still a little better
69gr MatchKing - BEST
77gr MatchKing - Just a little worse than 69gr but much better than 60gr VMax


At least in my case, as the weight increased the groups shrunk and 69gr is the sweet spot for me.
