Just bought a DPMS A-15 with detachable carrying handle/rear sight.
Does anyone know what ammo I should stay away from (i.e problems cycling, etc) with this model? The barrel is stamped 5.56 1-9 (which I assume means it has a fairly fast rate of twist), and the receiver is stamped with .223/5.56.
I am figuring staying with 55 gn bullets is probably the safest bet.
Any thoughts?
Thanks
