For sale is an P&S products carbine length RAS rail. Perfect for an M4/MK18 clone. The government now owns the original Knights armament design and has contracted P&S systems to manufacture this rail for the military alongside the Knights armament rail. Once again this is exactly the same as a Knights armament M4 RAS. It is spray painted tan so I am asking for $80 shipped. Also included is the standard foregrip that has never before been mounted. Email me for pictures. Thanks for looking.
