USMC XM-3 clone

Since the FA762SS is an OTB suppressor, the alignment tab is down inside the mount cavity.
 
Here's another photo - of a shiny unused one .....:

Does the pin engage anything when the suppressor is tightened down or is it loosely fitted solely for alignment?
 
I’m dying to know how you know this ….. is this Bill C.?
Ha sorry for the delay. Ironically been on a hiatus fishing like Bill does over the summer but no...I am not Bill.

Info came from some very knowledgeable people in the circles that count.

Yep. Wasn’t cheap but I can’t swing $5k+ for the real deal
 
Anyone ordered one of the IBA XM3 scope bases from PTG?
I’m trying to hold out for LRIs offering, but after picking up a PVS-22 this week, I’m ready to get these parts sent off.

PTG did say for an extra $20 they would engrave the S/N of the receiver on the left side like the real XM-3s have.

Not yet but i've been keeping up with them doing all these clone parts - the dudes are super committed to getting things correct and supporting the clone community.

Can't wait for some of the other projects they have coming out
 
Thinking of selling a couple guns to fund an XM3 build. I've been going back and forth on a M40a1 build. I think the XM3 might be a little more exciting. Wanted to start the long haul for finding a good builder/parts. I think suppressor/flash hider will be the bitch of the build. But wanted to see about a builder. I know with m40's there are preferred guys and they seem to be disappearing... Is there a specific smith recomendation for the XM3 build?

He has been talking about retiring.
 
Just a heads up. PTG will engrave the SN of your receiver on their IBA xm3 scope base for an extra $20

Real xm3 are not engraved with markings on the scope base on either side. None of the 25 issued rifles on CMP that sold are engraved.
 
Yeah I noticed that after taking a closer look at all the photos of the cmp guns. I had assumed the issued guns were from looking at the photos in this thread https://www.snipershide.com/shooting/threads/xm-3-on-cmp-what’s-the-story-behind-these.7114226/

I guess just the shop and civilian versions were marked that way. I like the idea of more serialized parts though so I had it done for mine.

Unfortunately, PTG is another one of those dealers who have absolutely no idea how the original rifles were made and marked. Just because they offer a something as a service, it doesn't mean that was an actual characteristic on a real military rifle.

There's nothing wrong with you building your rifle the way you want, just as long as people are aware that's not a characteristic on the issued USMC rifles. I went back and looked at my posts in that thread, and realized that I didn't specifically say that the markings on the test rifle's scope base are unique to that test rifle. I just updated that post so people are aware that the markings on the scope base were not on the issued USMC XM3's.
