JE Machine Tech .308 Carbine Buffer Tube Combo - Black

The JE Machine Tech PS-BTMCOMBO-308 is a complete .308 carbine buffer tube combo purpose-built for AR-10 / LR-308 carbine builds. This all-in-one kit delivers every component needed to finish the rear of a .308 carbine lower without sourcing parts individually.

The combo pairs a Mil-Spec carbine buffer tube with a matched .308 carbine buffer and a dedicated .308 carbine buffer spring - the heavier buffer and spring combination specified for .308 carbine platforms. A castle nut and end plate round out the kit for a clean installation right out of the box.

The black buffer tube is machined to Mil-Spec dimensions and accepts any standard carbine-length AR-15 / M4 pattern buttstock, making it a direct drop-in for AR-10 and LR-308 platform lowers.

Kit Includes:

• Mil-Spec carbine buffer tube
• .308 carbine buffer (black)
• .308 carbine buffer spring
• Castle nut
• End plate
