The Crosman 622
by Paul Hudson
The Crosman 622 is a rarity — a slide-action CO2 repeater.
The Crosman 622 is a repeating slide-action CO2 pellet rifle. It was produced from 1972 to 1978 in .22 caliber only. It uses the familiar 12-gram Powerlets and has a rotary clip that holds six pellets.
There have been only a few other slide-action repeaters available in the recent past — the Gamo Extreme CO2 and the Shark roundball repeater made in Argentina are two examples. The Gamo uses an 88-gram cartridge, and the Shark is a bulk-fill gun.
This particular 622 belongs to my brother-in-law’s friend. It had not been fired for many years and was in need of a resealing. The old factory lube had turned to hard wax, and several hours of cleaning was required to get everything in working order.
Due to its design, the 622 did not develop a reputation for durability. The valve body is made of two parts held together with a single screw and is prone to breakage. A second bolt or pin can be added to the bottom of the valve body to greatly strengthen the assembly. Another problem was the tendency for the gun to jam with certain pellets; this can happen if the muzzle is elevated when the slide is cycled. Some pellets (depending on their shape) can back out of the clip enough to prevent it from rotating. Keeping the gun pointed down will help prevent this. Possibly due to this problem, Crosman added a lever to the receiver of later 622s to aid removing stuck clips.
There are many parts in the 622′s receiver. The large, rectangular casting on the right is the valve body, and it’s prone to breakage. The probe is near the top of the receiver and is in the rearmost operating position. In the middle is the rotating rod that advances the clip. The large cylinder on the bottom houses the striker.
The 622 is large enough not to feel like a toy. It’s 40.5 inches long with a 13.5-inch length-of-pull, so it’s adult-sized. The blued barrel is 23 inches long, and the gun weighs 6 lbs. without a scope. A square post front sight and a square notch rear sight come from the factory, and they’re entirely suitable for the ranges at which the gun would be used. The painted receiver is made of two die-cast pieces and is grooved for mounting a scope. While the paint isn’t the greatest finish, no complaints can be made about the blueing on the barrel and gas tube. It’s very well done for a low-priced gun. Both the stock and forearm are made of varnished hardwood that has a very straight grain. The receiver is only about an inch thick, and the gun does not feel bulky; combined with the light weight, it’s a perfect plinker and can be carried for hours.
The rear sight is a simple square notch and is adjustable for elevation and windage.
The front sight is a square post. The ramp is textured to prevent glare.
A manual safety is mounted behind the trigger; it’s very similar to the unit on many other Crosman models. The single-stage trigger was a pleasant surprise. It isn’t adjustable…but it’s fairly smooth, mostly creep-free and breaks at a consistent 2 lbs., 2 oz. For an inexpensive airgun, it’s quite good. Holding down the trigger while cycling the action lets the striker travel forward with the slide; it will not fire the gun.
The trigger features Crosman’s typical cross-bolt safety and is surprisingly good.
The rotary clip
The 622′s 6-shot rotary clip is easy to load and fits entirely within the receiver; it will not interfere with a scope or catch on anything during handling. Unfortunately, the clip accepts pellets with a max length of 0.275 inches. This prevents longer domed pellets and pointed pellets from being used. All wadcutters fit, and most cycle fine.

The thin clip will not accept pellets over 0.275 inches long. The Baracuda Hunter is about the longest pellet that fits.
To charge the 622, the end cap of the lower tube is removed. A CO2 cylinder is dropped in nose-first (don’t forget a drop of Pellgunoil on the tip), and the end cap is replaced. As the cap is tightened, a slight hiss will be heard as the cartridge is pierced. Further tightening should not be needed. Since the CO2 cylinder seats against a flexible seal, it should be removed after shooting. A single cylinder was good for 36 shots, or 6 full clips. A two-cylinder lower tube, similar to that of the Crosman 160, was available for a time; but this was an aftermarket part not supplied by Crosman.
A single CO2 cartridge is used in the long gas tube.
The 622 was rated by Crosman at 450 fps; this gun exceeded that rating with all tested pellets. The temperature was around 90 degrees during shooting.
MV=muzzle velocity (fps), ME=muzzle energy (ft-lbs), ES=extreme spread (fps)
Getting the best accuracy from the 622 is a bit of a challenge. The forearm uses a single operating rod and can slightly rotate around the lower tube. This allows the gun to move upon firing if it’s held by the forearm. For best accuracy, support the 622 just ahead of the receiver by holding the gas tube. This is really a minor point; the 622 is not a long-range target gun — it’s a plinker, and one of the most entertaining ones at that.
10-meter groups with open sights
All pellets tested were more than accurate enough at 10 meters for plinking and informal shooting. Groups are 6 shots since that’s the magazine capacity. Here are a few of the best performers:
25-yard groups with a scope
The factory open sights just aren’t precise enough to produce the best accuracy at 25 yards. I mounted a simple 4x Leapers scope for these groups. Most pellets gave groups in the inch to inch-and-a-half range. There were a few standouts, however:
While the 622 isn’t the best engineered or most accurate airgun Crosman ever made, it’s still an interesting piece. There have been only a few slide-action airguns produced; and for plinking, the rapid-firing provided by a slide-action really ups the fun factor.
Many 622s are still in circulation, and they regularly show up at airgun shows and on auction sites. Lack of attention from collectors has kept the price reasonable. One caveat is to make sure the gun includes the clip — they fetch about 25 dollars apiece. It’s possible to load the rifle singly, but it’s tedious.
