ATI complete buffer tube kit
Reviewed on May 6, 2026Verified with Build

ATI sells this as a complete buffer tube kit with castle nut, end plate, spring, and buffer. Quality is on par with any other entry level kit. Buffer tube is properly anodized 6061 aluminum. Six positions click positively. Good way to spec out a basic build without sourcing individually.
