Q

Skeeter, member, from TN, United States, asked on October 12, 2026

will this work in a standard ar15 carbine buffer tube

AI Answer

A

Answered by OpticsPlanet AI, on October 12, 2026

Yes, this is a carbine length buffer (4 inches) designed to fit a standard AR carbine buffer tube, but it is weighted specifically for AR-9mm builds rather than standard 5.56/.223 carbines.
