M16A1 LPK - Grey or Black Ano. - Phosphate USA - RESTOCK COMING

INTL.MIL.CO – M16A1 Semi Lower Parts Kit – Parkerized – Made in USA

Restocked

Built for purists. This is a premium, historically accurate M16A1 semi-auto lower parts kit using genuine USGI components and top-grade subcontracted reproductions.

Key Features:

• Authentic USGI Parts mixed with new, USGI-grade investment cast parts from the same subcontractors (“the Pony”) used.

• M16A1 Selectors: OG Vietnam-era takeoffs (mostly 1964–1968 Colt and H&R). Reparked by John Thomas @ Retro Arms Works or used with patina.

• Hydramatic/HR Bolt Catches in stock and an optional choice

• Trigger: USGI-style semi-auto Schmid trigger, precision-ground sear face — same trigger used by the Pony since the ’80s.

• Finish:

  • Steel parts are finished in GREY manganese phosphate (not nitride or black oxide).

  • Trigger guard and mag release available in grey or black anodized — matched in-house to our lower receivers.

• All steel components oiled for corrosion resistance. Degrease with acetone or brake cleaner for a classic grey finish.

Most modern LPKs (except AR15sport) include imported or incorrectly finished parts. Ours are as close to vintage USGI as it gets — no shortcuts taken.

Perfect for:

• Retro M16A1 builds

• MK12, MK18 Mod 0 clones

• Serious collectors and reenactors
