Can somebody help me identify this?

[shoot_steel17]

I'm hoping somebody can help me with the name of this attachment. It's not mentioned in the nomenclature of the M40A6 and I've tried searching for things such as buttstock attachments and bag riders and can't seem to locate it. I'm guessing it's made by magpul but I can't find it on their site either. I appreciate any help.

Maybe never made it to production? The picture is from a prototype I think; it looks a little like something LaRue makes called a Tactical POD (Prone Optimization Device). Sorry I can't help much more.

It's part of the XTM Handstop Kit

I'm not the OP but that's a pretty good find, very clever of you! What do you think it's intended purpose was? It doesn't sit high enough to be a monopod and it wouldn't make any sense as a bag rider?

Probably used as a thumbhook and the part of the stock just forward is what rests on the rear bag.

Hi,

Thumbhook for sure

We are implementing something similar on all our production rifles.
Of course final version will be smoother and look better

Sincerely,
Theis

Good spot Trigger Monkey! OP, that "part" can be put anywhere there is a bit of Picatinny rail, I've learned, just because something was designed for a particular purpose does not mean that is all it will be used for! This was brought home when I saw some SF guys running Accu-Shot monopods as fore grips on carbines. I asked why and was told because they "don't break when doing muzzle strikes", which is why we started making the BT27 verticle fore grip. Gun guys doing gun stuff, gotta love it.

Actually I run that piece from the Magpul handstop kit and one of the rail covers on my AX AICS stock assembly. It’s a little lower profile than the stock piece and provides good surface area to rest the rear bag on.

Thank you all, and thanks Trigger Monkey that would be the one. I like how low profile the thumbhooks are and they work great to pull the buttstock into the shoulder. Theis I like the prototype, will keep my eye out for it.
