Changed Lower 3' POI Shift

were they otherwise dimensionally the same? should both be 5.900" long.

have you weighed them out?

those would be to very interesting data points to have.


this really has me scratching my head because, in theory at least, changing your buffer should have absolutely zero effect on POI/accuracy in general since a closed bolt is a closed bolt, and the AR system is designed to not have the bolt start moving until the bullet has left the barrel.

does beg to wonder if for whatever reason you were getting some wierd bolt tilt, or excess bolt speed causing the projectile to hit on something during feeding and either setback a bit, or tilt just a little so that it was coming into the rifling at a bit of a cant because of the deformation on chambering.
