Ruger AR Buffer Tube Kit, Carbine Length, Black
6 in stock
Description
The Ruger AR Buffer Tube Kit is a complete carbine length receiver extension assembly for AR-15 and M4 pattern lower receivers. Everything needed at the rear of the lower is here, from the six position receiver extension through the buffer, spring, castle nut, and end plate, which makes it a straightforward choice for a fresh build or a rebuild of a tired lower. Mil-Spec diameter tubing means the common run of collapsible carbine stocks will slide right on.
Builders who would rather source a matched set than assemble parts from four different bins will get the most out of this kit. Fit can vary slightly between AR-15 manufacturers and individual configurations, so installation by a qualified gunsmith is worth considering if you are not set up to torque a castle nut and stake it properly.
Ruger AR Buffer Tube Kit Features
- Six position receiver extension lets you index a collapsible stock to the shooter, body armor, or shooting position without tools
- 7075-T6 impact extruded aluminum tube holds up to repeated stock adjustment and hard use better than lower grade alloys
- Carbine weight buffer and matched spring deliver the cycling behavior the AR-15 carbine system was designed around
- Standard castle nut and receiver end plate secure the assembly and retain the takedown detent and spring during installation
- Mil-Spec outside diameter keeps the kit compatible with the broad range of commonly available carbine stocks
- Matte black hardcoat anodizing and phosphate coated steel parts resist corrosion and match the finish of most AR furniture
