Operating Cautions!

• Never attempt to insert the .22 long-rifle magazine in the rifle while the standard bolt group is installed in the rifle. Damage to the magazine will result.
• Never attempt to use the Unit in any AR-15 upper receiver that is not chambered for 5.56mm ammunition, or in any rifle not in good, serviceable condition.
• The M16/AR-15 bolt hold open feature will not work with the Unit. Visually inspect the chamber to insure there is no live ammunition remaining in the chamber when the magazine is empty. Some magazines may have a bolt hold open follower, but the Unit will close when such a magazine is removed.
