BSA is one of the oldest names in airguns, with a firearms manufacturing heritage stretching back over 150 years. BSA now offer a wide range of air rifles, the light and compact BSA Ultra SE, the longer and higher shot count BSA Scorpion SE and a range of R10 models and more recently the Goldstar SE, their HFT based rifle. They have just released the BSA Defiant Bullpup which is a first for BSA pushing into the Bullpup market.
BSA Ultra SE
The Tench Regulator and Tune package we offer on the Ultra SE Is a great way to keep the compact size but increase the shot count, accuracy and enhance the overall quality of the Ultra SE.

The Ultra SE does have an exceptionally small on-board volume with it being a carbine rifle, however thanks to the work done when the Tench Regulator is installed to improve air efficiency the shot counts can still be increased dramatically, and any power curve removed, giving you the perfect compact rifle with a large shot count without the addition of weight or length. The Tench Regulator installation still leaves the onboard gauge reading fill pressure and the addition of the regulator adds no length to the standard air tube assembly.
BSA Scorpion SE
These rifles offer a great deal of flexibility and are a great platform for customisation and performance development for those who want a rifle that’s a little extra special.

BSA R-10 (all models)
The R-10 is the most popular rifle we have in for work, to replace the standard regulator and customise with many options such as our 30mm carbon fibre shrouds which reduce the muzzle report hugely.

The Tench Regulator and tune package involves extensive changes to the standard BSA action, giving a much-improved performance in many areas. Some machining is required to install the Tench Regulator unit into the R-10 action as it fits in line with the firing valve, unlike the standard regulator which sits in the lower portion of the rifle. Because of this the air capacity of the rifle is slightly increased, further gaining shot count over the standard setup.
BSA Goldstar SE

BSA Goldstar SE’s with Tench Regulators achieve much higher shot counts than the BSA regulators, with their more efficient use of higher pressure air the pellets also often fly more accurately and with a better Ballistic Coefficient (BC), meaning a flatter trajectory, and more downrange power for the same power at the muzzle.
