I recently bought an AR style .22
the lower is an actual AR-15 .223, with a Chiappa M4-22 upper receiver, which is polymer.
I ended up spending almost $600 on this gun.
After about 700 rounds, the bolt broke on me. The rod that the spring went around came loose and the spring got all coiled up inside the slide.
I got it replaced, and it happened again.
Then i had to wait for 2 months to get it replaced again!
After getting this all solved i realized I couldn't get my scope sighted in. The scope seemed to randomly be unsighted. I would get it sighted in, and the next time i went to the range it would be messed up again.
Long story short, I found out that the barrel itself is moving!
it's not that anything is loose, it's just bending under pressure. The slight pressure from resting the barrel on a table causes my gun to shoot 6" high at 50 yards, as well as have a shit pattern.
I took him home and and measured the barrel. about 4 inches up the barrel, right below the scope my barrel moves .5mm just from me pressing on it when i have the butt stock in a mini vice.
You can see in the pictures below, the difference between resting the gun on a table, and then not letting anything touch the barrel while I shoot.
Anyone ever run into this problem? I can't help but think it's the polymer that's the problem. perhaps it's not thick enough to stabilize the barrel?
I ordered an aluminum quad rail and i plan to make the barrel physically fixed to the quad rail at the front and back, as well as the quad rail fixed to the polymer receiver.
I'm hoping this works.
I also thought of maybe putting the end clamp from the scope on the very beginning of the quad rail (which will be fixed tot he barrel)
so that if the barrel does happen to move, it has to move the quad rail and thus move the scope perfectly with it.
I'm kinda of angry as i've got almost $600 (about $700 now with the accessories) in a .22!!! it should shoot like a dream for the next 100 years for that much money.
both pictures are of shots at 50 yaards. No adjustments to sights were made, all i did was lift the gun up off the table so that the barrel was not resting on anything
