Blowback Buffer Spacer for use with 9mm/.40/ .357Sig / .45 / 10mm AR style firearms and standard carbine length buffers
-US Made with 7075 Aluminum
-Use when running a carbine buffer with a blow back system instead of buying an expensive longer buffer
-Helps lessen chance of breaking bolt catches by limiting the rearward travel of your blow back BCG
-Helps speed up cycling by shortening overall (necessary) bolt travel when using the shorter rounds/shorter BCG
 
*Get this product if you are building a 9mm set with a standard buffer system. You DO NOT need a heavier buffer OR spring for 9mm to function correctly. The combination of this spacer, a standard AR15 spring, and 3oz buffer will cycle reliable with OUR parts.*
