Manufacturer notes:
This spring is specifically designed for the Automatic Electric Shotgun Series from Tokyo Marui which use longer & stronger than normal AEG springs in their gearbox. Using normal AEG springs in one of these gearboxes could cause damage to your piston or other internals. These springs are Heat treated, use high-quality steel, and are made in England. These Springs are tested every 10 springs and measured for consistency during the manufacturing process. These are also deliberately made as a linear spring for a more consistent fps reading shot-to-shot.
This M100 Spring will produce around 345 fps. This is our biggest spring we can not make any bigger springs without detrimentally affecting FPS and ROF. Testing yielded large effects on ROF and Trigger response and battery life, this spring is so strong, we 100% recommend UPGRADING things like motor strength, battery power and or consider replacing the MOSFET with one from GATE ELECTRONICS. Otherwise, you may see the electronic MOSFET kicking in as the batteries quickly drain below 8V which sets off the MOSFET battery protection. We still consider this a viable product because there is always players wanting to fully upgrade their guns to cope with high FPS builds. This gun shooting 350 FPS at 70m with 25 - 30 RPS is pretty overkill though, so bear that in mind when going to sites, I wouldn't want to be on the receiving end of it.
**Tech note - FPS results may vary between guns and depend on upgrades, hop rubbers and air seals. We do a full range of springs with consistent power increases so you can change up or down if you aren't getting the results you desire**
