I'm trying to help a buddy figure out what the heck this is. My lame guess is a stripped topcover for something big. I've looked around the web for pictures of a live one but so far no luck.

For reference, overall its approximately 11 and 11/16" long, 2" wide and 2 and 1/2" tall.

Any help would be appreciated, Thanks!

The part number 7308856 would indicate that it is a "hinge Block Breechblock" with National Stock Number 1015-00-305-0754.

Numbers, we got numbers

7308856 is the drawing/part or "reference" number K might be Kelsey Hayse Wheel Company a maker of Cal .50 BMG's 19206 is I think Springfield Armory assigned ID number 19204 is RIA this number indicates the Ordnance facility responsible for procurment.

Hey guys, thanks for the help. Its way farther then I've gotten so far.

Speaking of Kelsey-Hayes here's a sad but cool piece:

I'm sorry did I forget to mention its for an M40A2, 106mm Recoiless Rifle. A picture appears on page 1-6, FM 23-82, 106-MM Recoiless Rifle M40A2 dated 30 July 1973.

As always, this place rocks. Nothing like getting chapter and verse for where to look! Thanks for the help, I was so stuck on the topcover thing and thinking maybe 20MM or something that I never would have thought to look through recoiless stuff.

Awesome!!!
