Snowpeak AP900B Aluminium Tactical Regulated PCP Air Rifle

The Snowpeak AP900B takes the proven AP900 platform and increases one thing that almost every PCP shooter appreciates: air capacity. By replacing the slim air cylinder with a larger 350cc aluminium bottle, the AP900B offers considerably longer shooting sessions between fills while retaining the same regulated action, smooth side-lever operation and compact tactical layout that made the original such a popular choice.
 
The trade-off is simple. The larger bottle adds a little more weight towards the front of the rifle, making it slightly less suited to long days carrying it across fields than the standard AP900. In return, you spend less time filling and more time shooting, making the AP900B an excellent option for target shooters, static pest control and anyone who prefers extended range sessions.
 
350cc Aluminium Air Bottle: The larger regulated air reservoir provides significantly more usable air than the standard AP900. Depending on calibre, power setting and pellet choice, expect approximately 80 to 160 shots per fill while benefiting from the consistent velocities produced by the integrated regulator.
 
Integrated Regulator: Stable air pressure is one of the biggest contributors to consistent accuracy. The factory regulator helps maintain repeatable velocities throughout the useful pressure range, giving predictable point of impact over extended shot strings.
 
Smooth Side-Lever Action: The right-hand side lever provides quick and effortless cocking for fast follow-up shots while keeping the shooting position comfortable and natural.
 
Reliable Rotary Magazine System: Supplied with Snowpeak's reinforced Mammoth/M-Series magazine, the AP900B feeds reliably while also including a single-shot tray for target shooters who prefer loading pellets individually.
 
Compact Tactical Layout: Although fitted with the larger bottle, the AP900B remains surprisingly compact. The folding synthetic stock reduces the rifle to approximately 600mm for transport, making it easy to store in vehicles or carry between shooting locations.
 
Integrated Moderator: The factory-fitted moderator helps reduce muzzle report without increasing the rifle's overall length unnecessarily, keeping the package neat and practical for both range and field use.
 
Modern Accessory Mounting: A full-length Picatinny rail allows straightforward optic installation, while the M-LOK compatible forend provides mounting options for bipods and other accessories where required.

Important Information
Please note that although the rifle is supplied with an integrated moderator, the larger bottle sits close beneath the barrel. Some aftermarket 1/2" UNF moderators may not provide sufficient clearance and could contact the air bottle. Any contact between moderator and bottle may affect barrel harmonics and potentially cause wear over time. Always check for adequate clearance before fitting aftermarket accessories.
 
We do not recommend purchasing the .25 calibre version in sub-16 Joule specification. At UK power levels, heavier .25 calibre pellets can be difficult to stabilise consistently, and accuracy may vary significantly depending on ammunition choice.
 
Who is the AP900B for?
The AP900B is aimed at shooters who liked everything about the original AP900 but wanted to spend less time filling their rifle. The larger bottle makes it particularly well suited to longer range sessions, static target shooting and pest control from hides or fixed positions where outright portability is less important. It isn't trying to be the lightest tactical PCP available. Instead, it offers a sensible balance of shot count, consistency and modern features at a price that's difficult to ignore.
