NR .308 rifle parts interchange mainly upper/lower receiver

[chriss]

Hey guys,
I'm mainly interested in the BCL 102, Troy 102 and stag 10. Are these uppers and lowers interchangeable? Like can I have a BCL 102 lower with a Troy 102 or Stag 10 upper?
Sorry if this is a stupid question... I'm fairly unfamiliar with these.

No you can't. Maybe troy 102 and bcl but not the stag. But there is compatibility between the stag 10 and the mapleridge armory upper and the soon to come lower.

The Stag 10 and Matrix 10 are both slant cut KAC / LMT style. The 102's are DPMS style.

Has the BCL/Troy compatibility been confirmed?
