Precision expectations from a 16" HBAR AR Carbine (non-free float)?

[rantingredneck]

I'm new to AR's.

Built my first one just a few months ago. TI stripped lower with Armalite LPK and factory RRA HBAR 16" A3 upper.

Only mod so far is a Midwest Industries 2 piece quad rail (non-free float).

I've been shooting irons with it at 25 and 50 yds and have been happy with the way it shoots, but hadn't really been trying for best groups. I recently purchased a Millet DMS-1 for it and today was my first range trip.

On 4 power off a front sand bag only I managed to keep a full 20 round mag in just about 2" at 100 yds. This is better than I expected from this rifle.

Were my expectations off or is this average for a 16" HBAR without freefloating?

I'm pleased with it. I wasn't after precision rifle level performance and really wasn't expecting 2MOA performance from it without some additional tweaking.

if assembled right, the rifle should do that well, maybe better. How good is all up to you, my friend.

Sounds about right to me... you should be able to do around 1.5" with match ammo that the rifle likes.

I can group 5 rounds in a ragged hole at 100 yards with my stock Olympic AR, using my reloads. It's a 16" bull barrel with a free float tube. What ammo are you using?

Good to know, thanks. I'm new to AR's so I didn't really know what to expect. All my other centerfire rifles are Rem 700 bolt guns.

BTW, ammo used was Federal XM193.
