LBE Unlimited AR-15 Upper Receiver Parts Kit

A stripped AR-15 upper receiver arrives without the two assemblies that make it work, and this kit covers both. Inside are one forward assist assembly and one ejection port door assembly, which is exactly what is missing when a receiver comes bare off the shelf.

LBE Unlimited builds AR components across the board, from upper receivers and bolt carrier groups to barrels, grips, gas tubes, buffer tubes and springs, so the small parts follow the same pattern as the rest of the line. The forward assist is retained by a roll pin and the port door rides on a pin held by a C-clip, so the install takes a punch, a small hammer and a few minutes at the bench.
