Had these on the AR for a couple years now and am looking to change it up some. Fore End is the carbine length customizeable (YHM-9431A), does NOT come with rail. I drilled and tapped a small hole for a 8-32 set screw to act as an anti rotation device. It works very good (did it to my wife's gun too). Finish has a few scuffs here and there and the rail has some finish wear, but still functional and in good shape. Asking $65. ***SPf** Folding sight/gas block is (YHM-9394). Asking $85. ---------SOLD AND GONE-------- Not really looking for trades as I need the $$ to buy some tools and other parts.
