This is the stock krytac LMG used but has no problems. I’ve upgraded the externals quite a bit though, I’ve extended the barrel added a carryhandle, scope, and different mag. The mag is an sound activated auto winding 5000 round hicap with and ISIS hunting permit sticker on which is easily removeable. I have invested about $600 into it. I WILL NOT TRADE. Buyer pays first then I will ship and pay for shipping. Ask for more photos if you want any. I will also meet in person if you are 30 minutes or less away or if you are willing to make the drive.
