Allen Engineering Thread Protector for the AEM "Ops Inc #12" brake mount

authentic Allen Engineering thread protector for your Mk12 build

This is the thread protector that is needed for the Allen Engineering brake mount.  100% genuine, made by Ron Allen.  This is one part of three parts that you need for a Mk12 build, or for any other barrel with the #12 / AEMB mount.  This thread protector will also work for Allen clone mounts, from BCM, Otter Creek and Centurion.  Many of those companies do not offer a thread protector.  Any mount that is made for an AEM5 or OPS #12 suppressor or clone, this thread protector will fit just fine.

Perfect for:

• Mk12 Mod 0
• Mk12 Mod H
• NSWC RECCE rifles
• "Gordon Carbine" builds
