Gun Watch Posted March 5, 2013 Report Share Posted March 5, 2013 BSA Scorpion SE John Bowkett Custom £650 .22 Air Rifle Private Seller Used - Mint Condition sheffield, South Yorkshire Pre-Charged Pneumatic Description This Scorpion SE has been Re-worked - Blueprinted - Regulated - Tuned and fettled by the master himself John Bowkett, a lot of work and money has gone into this rifle. John made a special regulator to fit my SE, the rifle can be filled to 250 bar, which will return 95 regulated shots approx. The Avg Muzzle velocity when I last chronoed was 597FPS using Defient 14gr 5.52s. giving the rifle 11.08FTLB approx, and will produce a 1 1/4 group at 50yds, and my eye sight is not the best The Barrel has been re crowned, and the shoulder machined exactly 90 degrees to the bore. Breech entry has been modified for better feed. Breechblock has been fitted with an over sized hold down screw to make it more secure. The magazine bridging tray is modified, and so is the bolt nose. The hammer assembly has been lightened and fitted with a synthetic guide made as a one off, to exactly fit the hammer spring being used. The hammer travel ( stroke ) is a short 6mm giving a fast lock time. The hammer tube itself is honed and polished. The exaust valve rear seal is modified, valve seat re-cut and the body is drilled and tapped to accept the oversize breechblock hold down screw. The valve itself is changed and the body is modified to accept the internal regulator that john made for me, which contains NO springs. The regulator does not interfere with the workings of the factory pressure guage which continues to read the main reservoir air pressure. The inlet valve body is machined and fitted with a John Bowkett fast flow valve, which is maintenance free, and pump friendly. Trigger sears are all polished and set to finer tolerances, so the shot release is ultra smooth. The trigger itself is bored out and fitted with an oversize pivot pin to remove annoying sideway wobble. There is a Bisley adjustable butt pad fitted too. This is a custom rifle, above and beyond any that could be mass produced. I purchased this rifle in August 2011. Comes with strap, studs, 2 magazines, Hogan Decimator Moderator and scope.
