I have a used set of YHM Diamond series rails. It is the rifle length one. Comes with an end cap. Missing anti rotation screws. Mounted on, went to the range once with them, then decided I wanted something a little lighter. You can oder them from YHM for $2/apiece. $100 shipped.
I have a set of Midlength drop in rails from YHM. Used but in good condition. $80 shipped.
I have one stripped upper for sale. Was told it was a BCM, but has no BCM markings. Was going to use it for a build but then found a killer deal on a complete upper that I wanted. $40 shipped.
Magpul angled foregrip. Does not have the screw that holds it in place. I will include it for free with the purchase of the YHM Diamond series rail. You can get a screw from a hardware place to use if you want to (I have done it).
PM me here with any questions. Pics are coming.
