These parts provide pressure against the back of the 22lr bolt carrier group and increase reliability of both conversions and dedicated 22lr uppers.
Our novel quick insert design allows for one handed insertion and removal without the need for tools. Simply line up the insertion slot with the buffer retention pin, slide the plug into place and rotate 1/4 turn until the pin sits in the slot of on the front face of the plug. Removal is is done in a similar manner, pressing in the buffer plug slightly and rotating the plug until the pin lines up with the insertion slot.
Designed to fit rifles and conversion kits with a CMMG/Atchisson/Ciener style bolt.
