I found a couple other interesting items at the Troy booth including two new drop in rail systems made for carbine length ARs with FSBs. Although I couldn't see exactly how they mount, they explained that it's a two piece (top and bottom) design. These may be a great option for those of us stuck with limited latitude in modifying our issued weapons. Hopefully some WEVO staff will get a chance to T&E these and report further.
