Ruger 57 5.7x28mm 10/20 or 15/20 2 Pack 10Rd or 15Rd Blocked Magazines 

CA, CO, CT, IL, MA, MD, NY, NJ, VT and DC Legal

Our 10/20 10 Round and 15/20 15 Round blocked Ruger57 magazines are made from brand new Ruger mags. We block them with an ABS block designed and made here in our shop. This block replaces the original spring base and allows the mag to be opened for cleaning in states that don't require epoxy. For states that require epoxy they will be blocked the same way just epoxied shut.

Our 10/20 mags are California, Connecticut, Massachusetts, Maryland, New Jersey, New York, and DC Legal.
Our 15/20 mags are Colorado, Illinois and Vermont Pistol Legal.
