CMMG Radial-Delayed Blowback Rifle Conversion Kits: Overcoming ATF Restrictions

Pistol caliber carbine fans have gotten quite the blow in the last few weeks, thanks to the ATF ruling regarding pistol braces. One of the many firearms affected by the ATF rule is the CMMG Banshee, one of the more popular options in the PCC realm. Not to take the abrupt change laying down, CMMG has pivoted and offered up Delayed Blowback Rifle Conversions kits in pistol carbine cartridges of .45, 9mm, and 5.7x28mm.

While the Banshee is still available to purchase with a pistol brace, it does require the necessary paperwork to acquire it. At the heart of the Banshee, is the short barrel rifle that gives the maximum portability and concealment in a small package. Constructed of aircraft-grade aluminum receivers, M-LOK free-floating handguards, and a myriad of Cerakote finishes, it isn’t hard to see why the Banshee is so popular.

But given the current state of the rulings, many current owners are looking to convert their PCC to a rifle, and out of the SBR range. Enter the Delayed Blowback Rifle conversion kits that take the Banshee from PCC to a rifle. The conversion kit does as advertised: it can take the 5.7x28mm, .45 ACP, or 9mm Banshee and make it a rifle, letting the owner skip all that paperwork.

The Delayed Blowback conversion kit includes a 16.1” barrel, barrel nut, CMMG 15” EML handguard along with a RipStock to round out the rifle. The barrel length along with the Ripstock are the key components that take the Banshee to the rifle length required by law, helping skip the registering process for an SBR and the months-long wait for that Form 1 paperwork to come back. As a side note the longer barrel fits with the Radial Blowback bolt carrier group, negating the need to swap out the BCG.

Available in six Cerakote colors, the Delayed Blowback Rifle Conversion kit matches colorwise to existing Banshee models and comes with the CMMG’s Lifetime Quality Guarantee. Cerakote color options include Armor Black, Charcoal Green, Coyote Tan, Midnight Bronze, Sniper Grey, or Titanium. The conversion kits are available in .45ACP, 9mm, and 5.7x28mm and each has an MSRP of $474.95.
