Description
The TacFire MAR139C Short Buffer Tube System is a 3.5-inch short buffer tube built for the AR pistol platform, trimming real length off compact pistol builds and backpack-gun setups.
Constructed of aluminum and finished in a tough black anodized coating, the tube resists corrosion and stands up to regular field use. A quick-detach (QD) sling end plate is included, so a standard QD swivel can be mounted right out of the box without sourcing a separate end plate or sling mount.
Designed specifically for AR pistol lowers, the MAR139C installs with nothing more than a basic spanner wrench – no special tools or gunsmithing required. It is a clean, affordable drop-in for any builder looking to run the shortest possible footprint on a pistol-buffer setup.
