air rifle is a popular, precharged pneumatic Air Gun manufactured by BSA and sold worldwide. Widely used for both sport and hunting it has proven itself to be 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 the legendary BSA designerJohn Bowkett .Features
The gun provides spring-assisted loading bolts which is operated by a release mechanism. The gun is equipped with short silenced moderators, match grade barrel, a fully-chequered stock for better handling and grip, and BSA standard scope dove tails. It is designed to be used as a lightweight stalking gun for hunting vermin like rats and pigeons in cramped areas. It provides a two stage, adjustable, match grade trigger which can be calibrated to a very soft touch. It is provided with a manual safety catch 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. This is very useful in the multi-shot version.In the UK, it is also available in FAC versions (only the .22 caliber) requiring a firearms license. Guns shipped outside the UK are set to a limit that is legal in the particular region(for instance guns exported to
Spain are set at 18ftlbs limit).hot Count
The Ultra is equipped with a small 50cc cylinder thereby providing very low shot count compared to other similar pneumatic rifles. It provides approximately 40 shots/fill in .22 when cylinder is set to 200Bar. Moreover power supply of an ultra is unregulated. Therefore pellet speeds vary according to the pressure of the cylinder. Performance and shot counts of Ultra can be further enchanced with after market regulators and bigger cylinders [ [http://bsaog.co.uk/forum/index.php?topic=270.0 John Bowkett ] ] .
The count is further reduced to 35 shots/fill in .177 when cylinder is set to 232 bar. The low shot count in 177 is due to the fact that 177 pellets travel at higher speeds than 22 and hence more 'charge' is required to power them.
MultiShot 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 of the quarry, thereby allowing the hunter a second shot.
Drawbacks
The low shot count is the most often cited drawback. The moderator that comes with BSA guns are replaced with Weihrauch or Logun silencers to further reduce the rifle's report [ [http://bsaog.co.uk/forum/index.php?topic=1257.0 sound suppressor ] ] [ [http://bsaog.co.uk/forum/index.php?topic=1212.0 weirhach silencer ] ] .
