I can regularly get MOA with brass cased ammo. Not much better, but certainly adequate for the ranges at which the chambering is useful.What is accuracy like? Can it compete with a bolt gun like the CZ 527?
Yes - the standard AR firing pin doesn't provide enough protrusion to reliabily light off most steel cased ammo (which use deeper primer pockets). Either get an 7.62x39 specific AR firing pin or bolt, if you wanna shoot the steel cased stuff. Other than that - no issues to report.Any problems shooting steel cased Russian junk ammo?
None.Any problems shooting 154 grain SP ammo?
All homebuilts.What is the make and model of your AR?
