i have a new bushy 16 no ban m4. I traded a knife for a new knights arm. ras with vertical handle. the system went on no problems. BUT the bottom half seems to be alittle loose, is this normal? and is there any remedy to make it more tight? the top is tight as a drum. thanks for the info.
P.S. if your wondering what kind of knife i traded it was a sog baby seal. hey the guy had 2 brand new knight sytems and one rifle. no need for 2 rails and he liked my knife.
