Beeman Sportsman 1000 .22 Caliber Disassembly

Beeman SS1000 with scope before disassembly

Start by removing the two front screws in the fore stock and the trigger guard screws, then remove the entire action from the stock.

Scope and barrel assembly removed from the stock

Remove the barrel pivot screw and carefully take off the barrel while releasing the cocking foot from the bottom of the action. There are two plastic washers on each side of the barrel block. Don't lose these.

Make sure to remove the screw holding the scope stop on. Now remove the rear pin from the receiver that holds the plastic end cap in there.

Receiver clamped in wood blocks with compressor bolts

Fuzzy picture here shows four bolts that are placed in the rear of the receiver to allow the spring compressor to compress the spring. The bolts straddle the trigger assembly and the two large pins that hold it in. Once the spring is slightly compressed, the pins will tap out easily with a small punch. Note: the pins go one way. In this photo, they would be tapped from the left side and exit on the right side.

Now you can release the tension on the spring and remove the internal parts.

My gun was amazingly clean and well machined inside. I polished the ends of the mainspring, and then tarred the spring. Then I cleaned the piston, top hat and rear spring guide, and applied moly to the top hat and spring guide. I applied a lite coat of moly to the outside and inside of the piston, but kept away from the seal, where I used silicone grease to lube the seal itself.

Now you can reassemble, using light touches of moly on the barrel pivot bolt and plastic washers. I used blue Loctite on all screws when I put everything back together. Make sure you use the right type of screwdriver and get the pivot bolt nice and snug, as well as the two screws that secure the front of the receiver to the stock and the main screw in the rear of the trigger guard. These screws will play a major role in the accuracy of your gun.
