AR10 lower Question

[AKSpraya]

I found an Armalite AR10 lower will a DPMS 308 upper fit or would I have to get Armalite upper?

also I found the lower on gunbroker it has a hunk missing out the end of it would I still be ok to use or should I not chance it

heres a pic of the hunk that got takin out

Not sure about the missing hunk, but I would pass.

As for working with DPMS, no it won't. The AR10 and DPMS LR308 are competing and incompatible designs. You can't even swap mags.
