Colt IAR6940 Progress

[minuteman1636]

One step closer to piecing together a semi-auto Colt Infantry Automatic Rifle (IAR). While surfing GunBroker I found an LE6940 lower receiver set for sale. I had to have it to put on my IAR6940 upper receiver. I have a VLTOR Emod stock ordered to make the stock correct. I still need to buy a Colt charging handle and Colt bolt carrier group to make it a complete functioning weapon.

You'll need a TA11 ACOG SDO to go with it, too.

Why do you state the TA11 SDO?

I'm curious as I have never seen any optics referenced in the prototype phase of the IAR trials. Mexico is the only country to actively use the IAR and the photos that I have seen show iron sights.

Thanks for the input.

Where did you get the upper?

Where did you get the upper?

Two places have the uppers advertised. Aimsurplus and US Armamant Corporation. I tried to buy from Aim Surplus first but kind of got the run around. I then learned about US Armament Corporation. They are actually the company that manufacturers the uppers for Colt. They have them listed at https://www.usarmcorp.com/parts/part-list. I had a flawless transaction with great communication through USARMCORP.

Didn't know they were for sale. Cool project! I would like to see more pics. Could we get some shots of the internals of that beast? I'm curious what that heat sink looks like and how it attaches to the barrel. Could we get you to disassemble it and snap some shots?

Looks like a cool project! How much does that upper weigh? I imagine it makes for a pretty nose heavy rifle.

I'm deployed right now. I have not handled the upper yet. My wife sent me several photos of the upper when it arrived at the house. I will take and post more detailed photos when I get home in December.

Awesome! Until then, stay safe!

I just ordered 1 today from with knights rear sight. I already have a Colt lower, morgen ambie mag release, colt ambie selector, H2 buffer. I need a bolt carrier group. I found a colt enhanced extractor spring as well. I am going to mount my aimpoint pro on it. I will post pics when done. Hopefully next week.

I just got a full auto Colt BCG from AU. Also a vltor ambie charging handle. I also already had a grip pod from when I was in the Corps. I should have pics by mid-end of next week. I have everything in hand or on order.
