Unique mk18 sav rail upper. It has a chopped m4a1 Ris rail to mk18 length. It’s the same as they did with the gl/scc that didn’t make past trial. I have photos if needed. It’s one of the earliest Ris 2 rolled out confirmed with DD. C stamp upper, badger gen 1 ch, tool craft bolt, brand new DD 10.3 chf with pinned block, dated DEC 2007 sav Ris 2, a2 muzzle, also comes with the Cqd sling mount and rear mount. Only trade is a peq16 that’s not in to bad shape.
