EndoMag® 9MM (Restrictive States)

EndoMag RS - Color Options



MEAN EndoMag® for Restrictive States. This Restricted State EndoMag® comes already fully assembled in a new (depending on availability could be either a Gen 2 or Gen 3) 5.56/.223 PMAG® housing and is restrictive state compliant as an unmodifiable, 10-round magazine (fixed base plate). If you live in a restricted state that limits magazines to less than standard capacity (30 rounds), you can now utilize your standard AR lower and 9mm upper of your choosing with a Glock or Colt variant 9mm BCG.

NOTE: These are only available in BLACK and Coyote Tan currently. PMAG's are NOT currently available in FDE or ODG.

International Sales: YES. MEAN sells direct to US customers only. For International customers, please check with Brownells to see if they carry our products in your country. For over 75 years, Brownells has been providing quality Gunsmithing tools, gun parts, and service to the firearms industry.

CMMG Guard owners: We also offer a version of the EndoMag that works with the CMMG Guard. If you have a CMMG Guard please select the CMMG version in the Package Section during checkout.
