TacFire buffer tube QD spot
Reviewed on April 27, 2026Verified with Build

TacFire milspec buffer tube kit is a budget option that works. The QD socket placement on one side is awkward for right handed shooters - it sits where my support hand thumb tends to rest. Once you adjust your grip its functional.
