I have a knock VLTOR CASV rail system in black that I got in trade. The picture is tan, but it has been paint black (Allumahyde II)
I’ve never tried to mount it, so I can’t say how it’ll fit. But it seems pretty well made.
Asking $50obo or maybe trades?
if it’s a replica, then it’s an airsoft version, so i’m moving this thread out of this section so someone doesn’t try to mount it on a real weapon.
