View Full Version : Something interesting with S&W AR upper
So I got some S&W uppers in stock and was going about my normal routine of checking the gas key and such when I noticed an odd stamping above the gas tube hole on the receiver. Generally the M4 stamp (as seen below) is found ONLY on Colt M4's. So I am wondering if there was an over run of stamped M4 uppers and S&W got some of them??

Is it the same size & font, or is it a "me too" kinda thing?
(Not that I mind, it's kinda nifty & very aesthetically pleasing)

Exact same. This upper was meant to be on a Colt.

I'll have to sneak a peek at my COLT. But I don't remember it looking like that.
I'd swear my font is a thinner, roll mark/stampish looking thing. That looks engraved.

On OLD 6920's it had a thinner stamp. On newer Colt's it is fat like this one.

My bad, I assumed it was 5.45x39

No. I have not gotten my shipment of those in yet.

Dig it! Mine is old.
Interesting. What are the specs on these uppers? Do they actually have M4 feedramps? Twist rate?
Disregard! I checked the other thread, 1/9 twist & M4 feedramps.

IIRC, there was a court ruling against Colt for trying to trade mark the term M-4, saying it was not there property at the exclusion of all other manufactures making M-4 type weapons. Could this be S&W exercising the right to mark their barrel M-4?
I got mine back from S&W service about 3 weeks ago where they replaced the upper and it has the same mark. I'm not sure if my original upper had it or not.

My S&W 5.45x39 upper has the M4 marking. I noticed it when I was checking it over, I thought it was a little strange. I'd only heard of Colt's having it, pretty neat.
My complete S&W 15R 5.45 has this M4 mark too.
I have no idea what it means.

M4 feed ramps on them?
Yes.

Mine has the stamp as well.
All S&W AR's are now coming with them.
