G&G UMP speed issue and nozzle length

ScooterVauto · October 16th, 2011, 21:56

ok Compression issue followers - update
I changed the oring to a high quailty after market unit
I changed the stock ported cylinder with the Modify non ported

I Did a teflon mod to the cylinder head (on the CH Oring) and again once the cylinder head was
installed in the cylinder

I put a small amount of heavy wt Silicone shock oil on the stock Cylinder head thing...
(what is the tube the nozzle slides over called??) anywho i put some oil on it to
improve the seal between the Nozzle and said tube.

fired in a Modify 100 spring and finished with Doing a Remove & Re-install on the madbull 363mm inner,
including the teflon mod on the hopup rubber to barrel point.
the aeg is now showing 308 FPS to 324 FPS.

Once the UMP nozzle arrives and is installed I expect to see 350 Fps
using the Remaining Kit is currently has installed.
