CMC Triggers AR-15 8-Position Extended Buffer Tube Assembly Kit - A5 Length

The CMC Triggers AR-15 8-Position Extended Buffer Tube Assembly Kit delivers a complete, ready-to-install buffer tube system built around an A5-length extension for AR-15 platforms. This kit is precision machined from industry-standard 6061-T6 aluminum and finished with a MIL-A-8625 Type III, Class 2 hard anodized coating in black, giving the assembly excellent wear and corrosion resistance for hard-use builds.

The tube provides 8 distinct positions for fine-tuning stock length of pull, and it ships as a full assembly kit that includes a matching quick-detach (QD) end plate and an A5-style buffer. That combination gives AR-15 builders a true drop-in solution for any mil-spec lower receiver. Whether you are assembling a new rifle from the ground up or refreshing an existing build, this CMC Triggers buffer tube assembly delivers the solid, repeatable lockup and dependable performance that a quality AR-15 demands.
