Product description

AT3 Tactical A1 Retro AR-15 Lower Build Kit – M16A1-Style Fixed Stock Setup

Features

  • Includes the lower parts needed to complete a stripped AR-15 lower receiver for a retro M16A1-style build
  • Fixed rifle stock assembly gives the lower the full-length profile expected on classic A1-inspired rifles
  • Luth-AR A1 pistol grip keeps the lower closer to the original retro look than modern carbine grips
  • Includes mil-spec lower controls, fire control springs and pins, trigger guard, and receiver small parts
  • Uses a rifle-length buffer system instead of a carbine buffer tube assembly

The AT3 Tactical A1 Retro AR-15 Lower Build Kit is built for finishing a stripped lower on an M16A1-inspired rifle project. It combines standard AR-15 lower controls with a fixed rifle stock assembly and A1-style pistol grip, giving builders the lower-end parts needed for a classic retro profile without tracking down the stock, grip, buffer system, and small parts separately.

Note: This kit is not assembled. Stripped lower receiver is not included.
