No problemo. Our last batch of Dept 6520's are a mix of Dimeco and Colt Defense parts. That pic was my personal 6920.
I got a BCG like the one jar420 has, except mine has:
-no dimple(hardness test mark)
-no C or D stamped on side
-bolt is stamped MP on top and AM stamped on bottom.
-also carrier is full auto
Can someone tell me if this is Colt and or Diemaco?
BCG came from a supposedly and hopefully a factory colt 6920 upper.
I verified the barrel is Colt per:
-C MP stamp
-white paint near barrel nut
-4 stamped on barrel extention
And I verified the receiver is Colt/Diemaco per:
-D and A slashed stamped on side
-M4 stamped above gas tube
Please let me know, appreciate any replies
here's some, hope it helps
Looks like an LMT to me. At least the bolt does anyway.

Thanks for the quick replies. So possible a LMT at least the bolt. May I ask why it could be LMT?
Anyone on the carrier? I can post more pictures if need a specific angle.
You guys are awesome!
By the way I'm new here, just let me know what I can do to make things better.
Stress relief cut underneath the lugs of the bolt and the markings. LMT does both of those things. Nobody else does as far as I know.
I've done a lot of hardness testing and it's never left a dent as big as what's on that carrier.
I know I haven't seen it all, but unless you use a cheezy Telebrineller hardness tester, the dent left from the test is very small, probably unnoticeable under a parkerized finish.
