Pre-Charged Pneumatic (PCP) rifles are more popular than spring guns as the much lower recoil provides more confidence in aim for most people. There are some FT shooters who compete at a very high level with a spring gun, and a well-engineered gun, shot with some skill will be no less accurate than a PCP. There are some “dedicated” FT designs available, with the main features being a deep stock or adjustable platform ("Hamster") to rest on the knee while shooting seated, a high or adjustable cheek-piece to suit the large telescopic sights, and often an adjustable butt or butt hook. Many experienced shooters have chosen to use made-to-measure custom stocks for their rifles, and there are a small number of stockers in the UK who compete in FT and have a good understanding of the specific requirements of the sport.
