I have a knights armament handguard that I took off of a mk12 paid $350 for it new, asking $300.  Last I checked they were out of stock everywhere and very hard to find.

I also have a primary arms slx 4-14x44 FFP scope with the ACSS illuminated reticle.  This scope has 5.56 hold overs. Comes with ARMS #22 QD rings.  Scope new was $280 and rings were $135, asking $350 for the pair.

I can get better picture upon request, best way to reach me is by text, 715-409-1799
