Juit EGO valve MOD

you will need a EGO valve and a intimidator gen 2 or 3 spring

I cut the ego valve shaft with a dremel same lenght as stock valve

then reversed the timmy spring

Posted Image

The gasket MOD
I made a groove on the valve pin
5 mm away from the tip
used a timmy gasket
then shave it untill it fits tight in the valve
then add some grease
this will eliminate 50% of air blown from the back of the gun

Posted Image

Super Bumper MOD
I found this Oring in my box
first clean the surface & the oring with acetone
then crazy glue the Oring on the back of the ram
this will cancel a lot of the kick on the marker

no air on marker

Posted Image
aired up

either way the bolt can be installed or removed without any problem

Results IN MY CASE:

8 dwell 160 HPR and flushed LPR 292 FPS

sound was cut down to 25 DB on my digital DB meter

minimal kick

Eliminated all the blowback air by 95%

on my tests:
I use reballs on a SS bigshot and a 682 lapco bore sizer, red field Chrono

Disclaimer:
Im not responsible for any damage or if you null your warranty
in this case I made this mods because I dont give %$&* what happens to my markers, if this is your main gun prolly need a back up marker

I didnt invent the bolt or the cuts I made on it, this is a combination of all the good ideas I've collected over my years of playing paintball


I've contacted Macdev and let them know they can still improve this marker

future MODs:
solenoid subplate
LPR tester
planing to add a frontal valve bumper with an extra longer valve to compensate the mechanical dwell
make an aluminum ram with a lurker timmy spring
polish the ram and ramsleeve
put a gasket on a stock valve
use an autococker valve with gasket
modiffy the front ram sleeve
make my own poppit valve
a new manif

Now Im happy with my RX Posted Image

Posted Image give me any marker and I'll make it shoot better Posted Image
