CMMG AR-15 Magazine 9mm Conversion Kit - 2 Pack

When you use this conversion kit with the CMMG 9mm radial delayed blowback upper it’s possible to use your existing lower to shoot 9mm. By using the housing of a Gen2/3 Magpul PMAG, this conversion kit seats in your AR15 lower’s magwell, giving you room for up to 30 rounds of 9mm ammunition. This is all accomplished while keeping the last round bolt hold-open function possible. This conversion kit can be further modified to hold 10, 20, or 30 rounds, depending on your preference and needs.  

Features:

• 9mm Magazine Conversion Kit
• Works with CMMG AR 9 Radial Delayed Blowback Uppers
• Works with Magpul PMAG (Gen 1 or2) Magazines
• LRBHO Function
• Uses Mil-Spec Carbine Buffer and Action Spring  

Even when it is time to replace parts of this conversion kit, it uses a standard carbine buffer and action spring, making replacements easy to find and install. This conversion makes it possible for you to accomplish your goals without making upkeep more complicated.
