Colt M16A1 GI Parts Kits - A GRADE KIT

Item Number
7 reviews Write a Review




Finally obtained a limited batch of Original Colt M16A1 Part Sets. Sight assembly and barrel parts were carefully stripped as barrels are prohibited from import by ATF regulations. All parts are original Colt mfg. Parts are generally in good shape, but show wear and blemishes from 50 years of storage & usage. All parts included except barrel, barrel extension, lower receiver, auto sear and magazine. Upper receiver and bolt carriers are assembled. This is like being thrown back in time to the Vietnam era. Gotta move quickly on these as we have only so many left. We have just acquired our last buy on these… and gone will be gone. 


Original Colt M16A1 parts kit made in the 1980’s. Each kit features the triangular handguard, the teardrop forward assist and original bolt carrier group. All bolt carriers will have the "C" for Colt stamped on the bolt carrier groups. Each kit comes with all parts. All you need to complete your rifle build is a barrel and a stripped lower receiver. This is the only chance to get original vintage Colt kits. Condition is good. Barrel, and Lower Receiver - not included. 
Front sight assembly is in kit.

A GRADE KIT  (We choose not to sell the lower grade kit) – Stock in serviceable condition. You may choose your triangular handguard set: Either a fair to good condition (that comes with the kit – may have cracks or missing teeth) OR you may have a brand new production copy of the original triangular handguards (please specify when ordering) 

FREE with each kit: a brand new original Colt G.I. right hand triangular handguard, compliments of Sarco!

    Colt M16A1 Parts Kit

    This parts kit was amazing. I have built the M16A1 retro rifle I have always wanted. There are modern repros out there but nothing beats the genuine colt parts. The best part was that everything was basically broke in. The action works flawlessly, the trigger breaks crisp. I only ended up missing one small spring and all the teeth on the hand guard were present.

    M16A1 Grade "A" kit

    It's a decent kit for the price. It'll build into a good truck gun or beater rifle. Definitely been there and seen it, but is still fully useable.

    Grade A M16a1 parts kit.

    Look closely at the picture of the kit that they show. That is what you get. The description they give fairly describes what the kit will look like.
    I bought two "Grade A" kits and cosmetically were pretty beat up. There is a lot of finish wear on both receivers and the furniture is very dinged up and missing teeth. The missing teeth was mentioned in the description though so was to be expected..
    Both kits included a brand new replacement butt plate to replace the existing cracked one so that was a plus. And each kit came with an extra right side heat shield. I believe the butt plate and heat shield are new old stock GI parts.
    I haven't built them yet but it looks like all parts are there.
    I caught the kit on sale so the kits are OK for the price.
    I'll redo the receiver's finishes and am sure I'll be happy with the results.

    Got it on sale. I suspect at the sale price this is about the best deal still available for these.
