FN 509 9MM 10/24 10Rd or 15/24 15Rd 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.

• Factory FN Magazine
  
• 9MM
• 10/24 or 15/24
• 24 Rounds blocked to 10 or 15 Rounds
• Steel

For a 17rd blocked mag just add a note or email us after ordering.

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

** Oak Park IL is a 10 Round Limit on Magazines

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.
