[Hectic]

Wow necro post. But here goes.
They can crank crazy fps and crazy rof out of their parts just the complete boxes that are sold round here are mostly in the field friendly fps ranges because lets face it how many folks wanna buy a drop in box with a 150 spring in it? Noone and someone who is after that most likely has the know jow to swap a spring. Those buyin a drop in box want it easy peasy.
So youll see the 100 and 120 complete boxes more often then 150.
Their gears and motors are strong and ive heard of them running up to 190 springs no problem. Their cylender and piston parts work great together for sweet airseal and smooth operation those wouod be key in building big fps if you think about it. No knocking madbull parts just sayin lonex builds are just as capeable of big fps setups. To the OP grab a lonex drop in box you wont be dissapointed. Grab one of their sexy motors to go with it youll love that too.
