I've seen an "M" ID mark on both ARand M16 hammers and triggers over the past few years. In fact, just "dehorned" an "M" marked M16 hammer to use as an unnotched replacemnt for an "M" marked notched BM piece.

Anyone know who these folks are?

I bought a Rock River Arms LPK and it came with "M" marked hammer and trigger.

I think the machined part is from CMT. The M may be a casting mark from another company though.

The way I understand it, LAR bought out Martin/Marietta and they supply stuff marked "M". I have a "M" stamped upper that came from Jacks Black Rifle Shop in PA, I emailed him after this came up in another thread, and he knows one of the partners in the company so I guess he should know. He said they supply some uppers and lowers to Bushmaster and DPMS, now I dont know if they also supply the parts your refering to but maybe it will get you in the right direction, I also sent you an email pertaining to this also.

My Stag complete lowers had "M" hammers. I think the vendor put in RRA parts kits, though.

My Colt 6721 and Colt LPK has M marked hammers.

My LMT and Stag Arms LPK has C marked hammers.

All 4 of my RRA have the "m" in them, but they aren't all on the same side.

My AR hammers from CMT have a C like C...
The CMT triggers have a M.

I have a couple RRA (but I think they might be DPMS) hammers with the "M" and a RRA (for sure) hammer with the "M". I can't remember the hammer I got from M&A Parts. I think it had some sort of mark on it.

The "M" in my Colt stands for mine.



Honestly, I have no clue where the "M" comes from.

So it looks like we're all a bit up in the air about the M mark.

Ah well.  The pieces are well made. They work, and hold up; and I guess that's the important thing.

(And this is just a sneaky way to bump the topic, on the off chance someone who knows hasn't seen the original posting yet)

Wpnsman would be the one who might would know.  There was a thread beyond the archive engine that explained some of the markings.

According to this thread from the archive, Wpnsman said that the M marking is yet to be identified.

Is this the thread you were talking about, it's about a year old.

Have you seen this hammer? thread link

M is the head of MI6. I'm sure that being the head of MI6 is a great gig and all, but Q is the one with the really cool shit.
