M3 Grease Gun Mag Well (.45)

The .45 Grease Gun magazine well allows the shooter to use standard M3 magazines in the MGI modular weapon system. The magazine release button is in standard AR placement to assist in muscle memory. This magazine well is a drop-on accessory for use with our modular lower receiver. With slight modifications, this mag well also allows the shooter to use standard unmodified M3 Grease Gun magazines to feed ammo into existing Olympic Arms upper receivers. If not being used with an Olympic Arms upper receiver, please remember to consider the MGI Bolt, Barrel, and 2X Spring to go with this magazine well.
