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 surface — 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

M16A1 LPK Gray anodized parts
Sorry about the late review.. I ordered these parts to dress up my H&R A1 copy. This kit included actual original H&R marked parts like the bolt carrier release as well as other period non H&R parts. All match the correct grey anodizing on the H&R (Palmetto State) upper and lower. I swapped in the right US Collectors furniture and the whole vibe just brings back memories. Chris hits in out of the park as usual!

Just what I needed to finish my build
Intl Mil Co came through with a LPK I needed to finish my build. Will definitely purchase from them again.

Great Parts
The kit is top notch and exactly what I was looking for. There was a delay in shipping but Chris stayed in communication and was extremely helpful. Absolutely would buy again. Thanks.

M16A1 LPK
Great product and service as always from INTLMILCO. Matches great with my Hydramatic M16A1 lower for a Mk 18 mod 0 build.

M16A1 LPK w/H&R selector & bolt catch (all grey)
Top notch Schmid Tool lpk with correct finish and extremely rare and hard to source original H&R parts. I don’t know of anyone else putting together kits like this!

Fit and finish are top notch as always. Looks great on my Hydramatic lower.

LPK looks great
The LPK looks fantastic. I'm excited to install it into a Intl. Mil. Co. lower soon enough here.

Recommended Business!
Ordered this for my H&R retro build. After wiping the pieces down with acetone, they turned a nice grey color. Extremely satisfied with the quality of the LPK. After the initial confirmation email upon purchase, didn’t receive any communication. I inquired about the status of the order around 2 weeks after purchase, and I was promptly given an update - seller was very responsive and I received the shipment not long after. Highly recommend doing business with INTL MIL CO.

10/10 Would Buy Again
I read many great reviews about INTL MIL CO online and decided to go with the A1 LPK from them. Great customer service all around and all the parts were just what I needed to finish up my retro build. And I got cool stickers so thats a bonus.
