Fellows: I was "told" that you can "squeeze" 5 .223 rounds into the detachable magazines BUT you would have a hard time getting a 5 round magazine to seat into the rifle with the bolt closed.

Anyone have any experience loading 5 .223 rounds in these magazines and seating it into the gun? If 5 round loaded magazine is hard to seat can you "loosen" the retaining screws of the magazine bottom metal to get a 5 round loaded magazine loaded? I would "make up" the loose fit with spacers and then tighten the screws. I "assume" the front screw for the magazine bottom metal is the forward receiver screw.
