G&G SR15 E3 MOD2 - Ultimate assault rifle build - Disassembly & upgrades guide with range test 

SR15 by G&G are great, there is rly not much to do to make it perfect. Whole SR and TR16 series are the same, fantastic replicas

What did you do to yours?

It is not possible

Stock gears are like 18:1, short strocked 3 teeth, very good quality. Motor upgrade Depends on you gears and build, it will be diferent for high speed and diferent for dmr. With stock gears I use stock ifrit motor, it works well as you can see, for dmr i use ultimate gears thorque up and ultimate motor 30k

As far as I know, yes, it is replaceable with a retro arms shell. But I never tried by myself, The stock shell is very hard and I didn't have any issues with it

@@roddys_airsoft i'm just worried about the mosfet system. Because the original gearbox (looks like) can't take advanced mosfet such as titan, aster, perun

@@roddys_airsoft because if i can swap it to retroarms, the mosfet compatibility issues wont be a problem

@@joesajaDid you find out? Looking at getting the rifle but also want to fit a titan over the stock mosfet

so you say you don`t like "Paint it black"... ehh shame :)

@@roddys_airsoft i do love the original.
