Wow, I went out the range today (ended up going to Cherry Creek) after buying a new bushmaster H-bar carbine upper.
This damn thing surprised.
First surprise:
I had it on an Eagle Arm CAR-15 lower. I took it to th erange and borrowed a Rock River lower with the two stage match trigger and Vltor stock. Simple. Off with the old lower and on with the new. Nope, it would close with the RR lower. Muct check this out why at home. So anyways, I was shooting with a standrad mil trigger on a CAR15 lower.
I had the scope bored sighted in at home. Took it out and got the thing zero'ed pretty well shooting Winchester 223 USA 55gr ammo.
Surprise 2:
As I was firing at the 10 yard range (and there ws decent wind) I shot some groups just to see how well the darned thing worked. This damn thing (with a scope) was shooting right around inch groups (plus or minus a little). I was really surpised. This wasn't simply off a sandbag. No free float handgaurd. No match trigger. Basically a this is just an Hbar carbine. And I shot many good groups.
Without careful aim, I put a magazine through my prairie dog targets. I basically would get the target lined up and fire. I was trying to hit a "prairie dog", not hold the tightest groups. I wanted to get a shot off and there is also no "bullseye" on a PD. Firing a half box (10 rounds) at 100 yards with a decent amount of wind produced a 2.4 inch max group. Taking the two furtherest outliers out, I managed 1.7 inch group. Considering these were fairly rapid, and conditions, I can't complain.
Now I have to ask. Are H-bar carbines usually this accurate or do I have a "keeper"?
