Sylvan Arms CNVRSN Magazine Conversion Block for Glock Magazines – AR-15 Platform

The Sylvan Arms CNVRSN Magazine Conversion Block allows AR-15 pattern rifles and pistols to accept Glock pistol magazines, converting your platform to run 9mm ammunition. This adapter is designed for shooters building dedicated 9mm AR platforms or converting existing lowers for pistol-caliber carbine use. It eliminates the need for proprietary magazine wells and provides reliable feeding with standard Glock magazines.

Machined from billet aluminum with a black anodized finish, the CNVRSN Block installs into a standard AR-15 lower receiver magazine well. Installation requires removal of the lower's magazine catch and may require minor fitting depending on your receiver's tolerances. This is a semi-permanent conversion component—once installed, the lower is dedicated to 9mm Glock magazine use unless the block is removed.
