Want to sell a used Knight's RAS for carbines. This includes RAS, a Knight's vertical fore grip, Knight's plastic roll up for panels and 5 panels for the RAS. It replaces the CAR length plastic fore arm that is on your carbine now. I acquired this set up in trade from another AR15.com member and it is really cool, but I'd rather have the cash. $250 *** SOLD *** for all delivered in the lower 48. Or trade up to pistol cal flat top upper Paypal is OK, but please add 4%. Finally, please email me with questions, as I don't check IM very often.
