Most have pins that are .250"in diameter. That's what the Crosman MAR177 fits. Additional 10rd mags can be purchased, as can a single-shot tray. The mag and single-shot tray made for the Benjamin Marauder air rifle also fit the MAR177. Both items are shown in the accessory links for this air gun. Crosman's MAR177 is an AR-15 upper and attaches to an AR-15 lower. The lower is a firearm. The upper shown on this page is an airgun. Putting an airgun upper on a firearm lower does not make the entire unit an airgun. It's still a firearm in the eyes of the law. Do not shoot this in areas and locales that do not allow discharging a firearm, as you may be cited for violating the law.

AR-15 upper lets you shoot airgun ammo with your AR-15 lower.
