Was this a Field modification or what?

[Renegade04]

The other long gun with moderator that comes up in McGrady pictures is a carbine.



The proportions of everything on it look kinda funky to me (grainy pic on cell screen) and was what made me think slip over.

Another of the rifle gas now that I figured out how to get those to post.

It appears that he used an aluminum vinyl acetate stock assembly (or SP1 carbine lower assembly) with the SP1 Sporter upper assembly. It is hard to tell if the carbine pictured is a SP1 carbine with the XM177 FH/moderator or an XM177E2 build. The right side of the upper receiver would tell the tale. My guess is it is a SP1 Carbine. The barrel is too long for it to be an actual XM177E2.
