The BSA Ultra is a popular, precharged pneumatic air rifle manufactured by a subsidiary of Spanish manufacturer Gamo, BSA Guns (UK) Limited and sold worldwide. Widely used for both sport and hunting it has proven itself to be both accurate and reliable. It is an unregulated, pneumatic powered air gun available in both .177 and .22 calibres and with a choice of either single shot or multi-shot. It is one of the cheapest PCP air rifles available in the market. It was designed by BSA designer John Bowkett. Features The gun has a spring-assisted loading bolt, a match-accuracy barrel and a fully chequered stock. It comes equipped with scope mounts and silencer. Stocks in Beech and Walnut available as is a black synthetic stock. It is designed to be a lightweight stalking gun used for hunting vermin like rats and pigeons in cramped areas. It provides a two-stage, adjustable, match grade trigger which can be adjusted to provide a light pull weight. It has a manual safety to avoid accidental discharge. Unlike most other pneumatic air rifles that use the traditional bolt action system, the Ultra features a unique Micro-Movement Cocking (MMC) System for loading. The MMC is operated by means of a plunger at the fore end of the stock. In the UK, it is also available in FAC versions requiring a firearms licence. Shot count The Ultra has an unregulated power supply. Therefore, pellet speeds vary according to the pressure of the cylinder. The Ultra is equipped with a small cylinder, thereby providing very low shot count compared to other pneumatic rifles. It provides about 40 shots/fill in .22 when cylinder is set to 200 bar. The count is 35 shots/fill in .177 when cylinder is set to 232 bar. The lower shot count in .177 is because .177 pellets travel at higher speeds than .22 and hence more 'charge' is required to power them. It is now possible to get after-market pressure regulators fitted to Ultra's which give up to 100 full power (12 ft pound) on one charge. Multi-shot version The Ultra is also available in multi-shot version. This uses the BSA standard 10-shot rotary magazine. The MMC system allows the shooter to reload the rifle without taking the eyes or the rifle off target, thereby allowing the shooter quick follow-up shots. Drawbacks In the UK it is a standard practice to replace the BSA moderators
