Snowpeak AP900 Mercury 5.5 mm Air Rifle

Snowpeak AP900 Mercury 5.5mm Air Rifle

The Chinese company Snowpeak Airguns (SPA) is a true leader in the field of low-budget PCP airguns, and the Mercury AP900 model only confirms this—it stands out for its excellent craftsmanship, high modularity, and, given the features it offers, above all its unbeatable purchase price.

The Mercury AP900 in 5.5 mm (.22) caliber is equipped with a 310 mm rifled barrel designed for shooting lead pellets. The entire barrel is encased in a stylish shroud with a carbon-fiber-look finish, which gives the air rifle a much more premium appearance. The muzzle is fitted with a silencer; once removed, it reveals a 1/2 UNF thread for mounting a different silencer if desired. (For the AP900 and AP900 B models, only silencers with a body diameter of up to 28 mm can be used; a larger silencer would interfere with the air cartridge.)

The airgun is powered by air from a 118 cc aluminum cartridge. A significant advantage over the competition is the integrated pressure regulator, which ensures consistent muzzle velocity both with a full cartridge and just above the regulator’s threshold—this guarantees stable and accurate shooting. A simple pressure gauge located at the end of the cartridge informs you of the remaining pressure; this is also where the opening for the QuickFill filling pin is located, which features a connector for a quick-connect fitting.

Reloading is handled by the popular biathlon-style side-loading lever, which operates smoothly and features a grip large enough even for larger hands. For shooting, you can use either the pre-loaded magazine (2 included) or the supplied single-shot adapter.

The trigger mechanism allows for adjustment of trigger pull weight, trigger travel, and overall height and tilt. An AR-15-style manual safety is located on the left side above the trigger.

A major highlight of this model is the folding stock, which you first install on the rear Picatinny rail after unpacking the air rifle. This gives you a full-fledged long air rifle that can be shortened by 25 cm by folding down the stock; when folded, the stock is held in place by a magnet. The cheek rest is fixed, and the buttplate is surprisingly made of rubber instead of plastic.

A sufficiently long metal Picatinny rail is provided for mounting a rifle scope, and on the sides you’ll find two additional plastic Picatinny rails for mounting a laser, flashlight, or other accessories. The rubberized AR-15-style grip can be replaced with a different one, and the handguard is equipped with either M-LOK slots (on the version with a standard cartridge) or a bottom Picatinny rail (on the version with an air cylinder).

Although this is a low-budget air rifle, it is very well made. The main body of the rifle, the top rail, and the trigger guard are all machined from a single piece of aluminum; nothing wobbles, and everything holds together firmly. The plastic parts, made of high-quality polymer, feel sturdy and durable and do not negatively affect the air rifle’s overall function in any way.

We recommend purchasing the appropriate accessories for shooting and maintaining the rifle, which you can find below.
