with Weihrauch or Logun silencers to reduce the rifle's report. Separate after market fitments for regulators and bigger cylinders are available. The MMC action also did not enable the shooter to keep on target as the switch to release the probe was under the nose, then the probe would come out in a position behind the shooter's ear. Then the probe would have to be pressed in if using a multishot (not allowed when engaged in target shooting competitions) or a pellet rolled into the breech, then the MMC would have to be pulled back, lifting the barrel. Also, if the shooter wanted a bipod the best way was to put it on backwards so that the legs when folded point towards the trigger. It became popular to replace the BSA Scorpion barrel with that from an Ultra, leading to the "Scultra" and inspiring the design of the Ultra SE. "Ultra SE" The latest version (Ultra SE) features BSA's redesigned magazine, which boasts improved reliability over the previous model. The two-stage multi-shot system (MMC) has been replaced with a traditional bolt action assembly that increases the reload speed, and makes fitting and using a bipod considerably easier (due to the removal of the front plunger style cocking system). The hammer/valve assembly has been changed to a new 'Fast Strike' design which is claimed to increase consistency and shot count by around 20%. The factory fitted sound moderator has been replaced with a muzzle brake. The safety has been moved from the right to left hand side so as to not interfere with the bolt action. A pressure gauge is now present on the underneath of the stock, which enables the user to see how much charge is in the rifle.
