High FPS, but low range, why?

[-Dan-]

Hello all

i chronoed my gun at the last game i went to and its shooting at 375fps. But its range using .2 bb's is less than a stock TM gun. I think compression is ok in the gearbox as the FPS is high, Would some thing wrong in the barrel/ hop unit cause low range.

im stuck as to what it could be?

Try adjusting the hopup and or using .25's instead

Sorry forgot to add, this was with the hop up set at the right level.

If you've just recently put the gun together, sometimes your cylinder lube makes it's way onto the hop-up, rendering it ineffective. You may think you have it set right, but in fact it is not. You need to clean the barrel and hop-up with some silicone oil and keep swabbing it until the cloth comes out dry and clean.

Every second or third gun I reassemble suffers from this. Cleaning it solves the problem everytime.

Perhaps elaborate what kind of Aeg do you have and what are the internal set up?
