I live in Paraguay, south america, and have a post-ban Colt Lightweight Match Target AR15 rifle, 16" 1 in 7" barrel, chambered "223". It has the annoying problem of not being able to handle mil-spec 55 gr. ammo (the most common/cheapest here), while functioning perfectly with commercial 223 ammo. It breaks the rims of the cases, leaving them stuck inside (probably some problem with chamber dimensions or out of spec gas system). I have checked every single piece in the rifle (I have previously posted here and in AR15.com regarding this same problem), but could not find anything at fault. Probably there is some truth to the myth of some AR15 rifles chambered to 223 not being able to work with 5.56 military ammo.
I'm tired of not being able to fix the problem myself, and I would like to send the upper to a good american gunsmith. Could you please give me some recomendations? Thanks in advance.
