22LR AR15 QD End Cap - Bufferless Only

CMMG’s 22LR END CAP is the perfect accessory for your super short 22lr build.  This end cap can be installed in place of a receiver extension and buffer assembly by simply using a 3/8” hex wrench. The End Cap is compatible with all CMMG 22LR AR Conversion Kits, as well as any AR15 that uses a dedicated CMMG 22LR BCG and barrel.  Available in two variations:  standard version comes with smooth exterior and QD version has an attachment point machined into the exterior for attaching a sling.

**WARNING — Intended for use with RTB & CMMG 22LR Bolt Carrier Groups.  May work with other BUFFERLESS operating systems but we cannot guarantee compatibility.  To avoid bodily harm or firearm damage, DO NOT uses with buffered operating systems**
