The Crosman 66 Powermaster is part of the company's line of air rifles. The 66 shoots .177 caliber pellets along with BBs using pneumatic air. Reassembly of a Powermaster 66 requires few parts. Crosman designs its air rifles to be simple to use. The sights and the pellet clip are important pieces to put into the rifle.
Items you will need
Screw the sights back onto the top of the barrel and on the top of the 66's stock. The sights are front and rear. The rear sight has an elevated ridge called the elevator that fits under the sight sleeve, while the front sight is U-shaped.
Screw the muzzle end onto the barrel. Find the screws on the side of the rifle. Slide the pellet clip into the channel between the barrel muzzle.
Screw the butt end of the stock back onto the main portion of the rifle. There are three screws to tighten: two on the sides of the stock and one large screw under the stock. Tighten the screws so they are flush with the surface of the stock.
Slide the BB retainer rod through the top section of the muzzle. Push the rod until it triggers the lock spring, keeping it in place.
- Adjust the front sight elevator using the two front screws. Loosen, then slide the sight left or right to adjust for windage, and slide the elevator up or back to adjust the vertical sight.
