Missouri-based CMMG this month announced what is billed as the company's shortest and most compact Banshee model ever, the .22LR End Cap. 

Chambered in the popular rimfire staple, the new blow-back action Banshee deletes the buffer tube and receiver extension common on AR-type pistols and replaces it instead with a capped lower receiver. This produces a smaller format gun than most .22LR AR15 builds on the market  as short as 14.7 inches in the 4.5-inch barrel model. CMMG says the .22LR End Cap is compatible with all of the company's .22LR AR Conversion Kits, as well as any AR15 that uses a dedicated CMMG .22LR bolt carrier group and barrel.

The pistol will be offered in a 100 Mk4 Series gun with a 9-inch barrel, a 200 Mk4 with upgraded Magpul MOE furniture and a better muzzle device, and a 300 Mk4 with a short 4.5-inch barrel that ends in a KAK Slim Flash Can. All use a forged 7075-T6 M4 type upper with an AR15-type lower, sport a single-stage Mil-Spec style trigger, and carry an M-LOK handguard. All are threaded 1/2x28TPI pitch for common muzzle devices and suppressors for those seeking some quiet time. The guns use a 25-round magazine. 

The CMMG .22LR End Cap 100 Mk 4 has an overall length of 17.5 inches and a weight of 3.6 pounds, unloaded.
The CMMG .22LR End Cap 200 Mk 4 has an overall length of 18.1 inches and a weight of 4.25 pounds, unloaded.
The CMMG .22LR End Cap 300 Mk 4 has an overall length of 14.7 inches and a weight of 3.5 pounds, unloaded.

CMMG plans to offer the newest Banshee model in a kaleidoscope of no less than 10 different Cerakote finishes. 

Besides Graphite Black, Titanium, Slate, OD Green, Flat Dark Earth, Sniper Grey, and Slate, CMMG will offer the .22LR End Cap in Stormtrooper White, Burnt Bronze, Midnight Bronze, and Bazooka Green as well. 

The End Cap's receiver cap is available in two variations: standard, with a smooth exterior and CMMG logo and a quick-detach, able to swap out with the aid of a 3/8-inch hex wrench. Banshee 100 Series guns come with the logo cap while the 200 and 300 come with the QD cap installed. Either cap can be purchased separately from CMMG for under $30. No word on if the company plans an M1913 cap to add a stabilizing brace, which seems like a logical accessory – at least for now. 

MSRP on the complete CMMG .22LR End Cap Banshee pistols range from $799 to $1,024 depending on the model and include CMMG’s Lifetime Quality Guarantee.
