AR-15 Reinforcement Kit


In Stock!

This Reinforcement Kit contains all of the small items needed to reinforce your 3D printed AR-15 Super Lower.

SKU: RK15 Category:

This kit contains the small reinforcement parts that are key to a strong AR-15 Super Lower. All you will need to complete your  lower is an AR-15 lower build kit. Or you can pick up our AR-15 Combo Kit and get everything you need to complete your lower at once!


This kit is also compatible with our AR-9 Super Lower, however, since AR-9’s require a heavy 9 mm buffer, we recommend that you simply purchase the complete AR-9 Combo Kit which includes all of the proper parts in one kit.

Included in this kit:

  • Four brass hammer and trigger pin Bushings.
  • Front Take Down Pin Plates and hardware.
  • Black Oxide Stainless Steel Buffer Reinforcement Band.
  • Brass insert and bolt for the pistol grip.
  • Bolt and Nut to use with the Hoffman Tactical Stock System
  • Bushing Installation Tool

All hardware is Stainless Steel, except for the brass inserts, which are brass.
