QB78 Airgun Oversized Bolt Handle Replacement A deluxe replacement bolt handle for the QB78 Air Rifle. Gives a better grip and more leverage... But let's face it: This bolt handle just looks so nice! Complete Instructions Included: Remove the barreled action from the stock to access the rear of the top receiver tube. Loosen the set screw that holds the original bolt handle. Replace it with the new bolt handel. Tighten the set screw and re-assemble the barreled receiver into the stock. See all of our QB78 accessories, parts, and rifles at our QB78 Home Page.
