TacFire MAR047-H2-B H2 Carbine Buffer Tube Kit - Mil-Spec 6-Position Tube w/ M4-Style Stock

The TacFire MAR047-H2-B H2 Carbine Buffer Tube Kit (manufacturer part number MAR047H2B) is a complete rear-end assembly for AR-pattern rifles. It brings the buffer tube, buffer, spring, end plate, castle nut and an M4-style stock together in a single kit, so you can finish out a lower or replace a worn mil-spec setup in one purchase.

The buffer tube is machined from 7075-T6 aluminum and paired with a steel buffer and steel buffer spring, with an anodized finish on the tube. This is a mil-spec six-position tube with a carbine-length buffer spring, supplied with a regular end plate and castle nut to complete the installation. The kit is finished with an M4-style stock for a standard collapsible adjustable-length setup.

Kit contents as published for this configuration:

• 1 mil-spec 6-position buffer tube
• 1 M4-style stock
• 1 buffer
• 1 carbine-length buffer spring
• 1 regular end plate
• 1 castle nut

Keep in mind that buffer weight and tube length both change how the rifle cycles. Match the tube to your stock (mil-spec or commercial) and match the buffer weight to your gas system and the ammunition you shoot. This kit is supplied in new condition, ready for the bench or the field.
