Gerber’s latest offering to AR-15 owners goes above and beyond when it comes to field maintenance. The short stack fits into the bottom of any Magpul-style foregrip. It separates into 3 pieces, and gives shooters the tools they need to strip and maintain their weapon. The Short Stack has tools to adjust the stock and flash hider, scrape and clean firing pins, tighten and loosen every nut and screw on the weapon — and more. It’s coming to stores shortly, but you can check out a preview now.
