I recently converted a brand new TM NGRS Mk18 to a MK16 DMR and I have these left over. Parts never fielded. There is very minor wear on rail and threads from the removal process and orange tip removal. You get everything seen in pics. Includes: TM MK18 licensed 9.5 inch handguard, TM MK18 10 inch outer barrel, TM MK18 gas tube, TM MK18 barrel nut, TM MK18 charging handle, TM standard sling mount and QD sling mount, Laylax steel barrel base for stronger tightening, Bavtac MK18 barrel nut tool for correct assembly. Everything is in perfect working order. This is everything you need to convert your NGRS to a MK18. I’m also throwing in a steel breecher style flash hider. Free shipping anywhere in the lower 48.
