This is the MAGNUM ADJUSTER for 22XX. It's made of 6061-T6 aluminum anodized black. It has a locking collar and tick marks on the back of the knob to help gauge and maintain adjustments. The hammer spring can be removed by backing the adjuster knob all the way out. The adjustment range is wide enough to produce maximum power, maximum shot count or any level of performance in between. It fits 1740, 2240, 2250, 2300T, 2300S, 2300KT and 2400KT.

 It allows you to get more power when you need it or more shots when power is not critical. At minimum power it produces about 175 shots from a 12 gram cartridge, at full power about 25 shots. Minimum power is generally 250-350 FPS depending on barrel length. Maximum power is generally 525-750 FPS with longer barrels producing the higher numbers. In hot temps more power is produced because CO2 increases in pressure as it gets warmer. Using more striker spring tension reduces shot count but produces more power up to a certain point. Too much tension can waste CO2 without producing extra power. It can be used to help balance performance due to temperature changes.
