Hey, I recently took my 16" BCM midlength upper to a range, and shot with a 6x Barska scope. I was getting hand sized groups (that is to say, ~8-9" groups) with 30 rounds at 100 yards. Now, I'm not a good shot at all, and didn't really zero my scope (got a 2" 3-shot group at 25 yards and said good enough).
I was using PMC bronze and WMA .223 55gr ammo in a 5.56, 1x7 barrel, so that might also affect accuracy (or so I'm told). Anyways, I'm curious, if anyone has a BCM midlength upper, what is the full "potential" of the rifle? Edit: Meant to say WPA ammo.... I was at a Wildlife Management Area (WMA) which is what was the mixup but I digress..... |

Cheap ammo + cheap scope + a self proclaimed below average shooter will get you bad groups...
I generally shoot XM193 out of both of my BCM uppers and can get 2"-3" groups @ 100 yards if I really try. I've done slightly better with match ammo but then again I'm not the greatest shot either. |

Your scope bouncing around (whether it's the mount not being tight enough or the actual scope sights moving around due to it being a cheaper scope) will probably throw you off a ton. I'd try your irons out and keep it steady and see how you do. I'm actually better at pure accuracy shooting using my irons than I am with my red dot. |
You def need a better scope to go with that BCM upper. I don't under why people put good money in a rifle and throw a cheapo scope on the top of it. No offense, just trying to help. Get a Vortex PST, Leupold VR-X, or something decent on that bad boy and you will be g2g!

My general rule of thumb for matching a scope to a rifle is you should spend about 50-75% of the value of your rifle. I cant have a $1k rifle and a $50 scope and expect tight groupings. |
+1 on the scope. I had a Barska and it would NOT hold zero. It was a new scope on an old gun that I knew very well. I put a Nikon on it and the groups went right back to < 1MOA. I should have known there would be an issue when I took off the turret covers and found:
Yes, the top turret was marked "UP" as well. |

You sure you don't have it on sideways?  |
