cmm101m4

Upon further review, it looks similar to the sphur prototype, although I’m not sure.... Interesting setup among other things it looks like he has the supernova recoil tube with its collapsing stock added instead of the standard metal 3 position m4/m1014 stock and factory recoil tube.

I'll take 2

I have the B&T rail, and yes this looks similar, what is unique about this design if you pause the video and look closely is that it does not have rails just covering the whole thing, its smooth and acts as a heat shield similar to like a SPAS 12. Anyone have anymore info on this rail?? never seen it before and I've seen pretty much every accessories for this shotgun platform.

Need help! What hand guard is this? Video below: Thanks
