G&G GC 16 M4 Carbine
 

Hey guys I haven't seen too much around about the gun I just picked up so I thought I'd start a thread and maybe get some answers.

First thing I did was remove the metal flash hider(orange) and replaced it with a 7.5" suppressor I am already loving the look. I play at cqb games and would love to be able to use this gun instead of running my ICS MP5 A5 RIS. Unfortunately this thing out of the box came with an M120 spring and chronos at 415-420 so I'm going to have to downgrade the spring.

Here's the question, Is the Prometheus MS100 a good choice and will it get me under 350fps?

I may as well change the spring guide while I'm in there I was thinking, PROMETHEUS EG SPRING GUIDE W. SMOOTHER VER. 2/8, any thoughts?

Thanks for the help

M100 can get you under 350 (ditch piston head bearing will help) but an m90 will for sure. Good chance your gb already has bearings on both the piston & spring guide... G&g seems to like doing that.

Checkout airsoftstore.ca. You can get a lonex spring and guide for less than the prommy guide from your links.

Cool thanks for the info, ya maybe I should open it up and see what the situation is before I buy parts :p

Went ahead and bought a Modify S90+ from airsoftparts.ca as I didn't want to wait for shipping, will probably get to chrono it tomorrow and will post results.
