LBE Unlimited MILBUFKT 6-Position AR-15 Mil-Spec Buffer Tube Kit - Black$46.36
Availability: In Stock
The LBE Unlimited MBUF002 mil-spec 6-position AR-15 buffer tube is a straightforward, domestic-made replacement for AR platform builds that need a reliable collapsible stock adapter. If you're assembling a new rifle, upgrading an existing one, or stocking spare parts, this tube handles the job without fanfare—it's made to work with standard mil-spec collapsible AR stocks and comes finished in black.
LBE Unlimited has built a reputation for no-nonsense US-manufactured gun parts, and this buffer tube reflects that approach. Six positions give you adjustment options to dial in length of pull for your shooting style or body armor, whether you're running a carbine for duty, sport, or home defense. The mil-spec diameter ensures compatibility with the vast majority of AR-15 stocks on the market, so you're not locked into a single brand or model.
This is the kind of part that works quietly in the background—you install it, set it where it belongs, and move on to the rest of your build. Nothing fancy, nothing proprietary, just a solid buffer tube made in the USA that does what an AR platform requires.
