FN 509 9MM 10/24 10Rd  Blocked Mag CA,CO,CT,DE,IL,MA,MD,NY,NJ,OR,RI,WA,VT & DC Legal Magazine

Our 10/24 10 Round blocked FN 509 magazines are made from brand new OEM FN. 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.

For states that require sealing please let us know which base you would like on it as once sealed it can't be changed!!

Mags shipped to NY, CO,CT, MA, VT & DC will have the base sealed shut with epoxy and a rivet to fully comply with the laws there.

For states that do not require the base sealed shut we can still epoxy it shut on request free of charge. Just let us know you would like it done.
