n1ckh Posted January 13, 2015 Posted January 13, 2015 A little while ago, I posted about my cm16 raider having FPS issues, I thought it was because the cylinder was dry (which it was) Turned out to be piston sooooooo I've ordered a SHS 14 tooth piston (same as original piston) with all steel teeth, SHS upgrade nozzle with O ring and SHS cylinder head with double O ring Once the piston teeth in my sons M4 do the same, I'll upgrade that one with the same mods Nick Sitting Duck and Lozart 2
Supporters Lozart Posted January 13, 2015 Supporters Posted January 13, 2015 That's exactly what's in my M4. Is niiiiiice.
n1ckh Posted January 13, 2015 Author Posted January 13, 2015 What spring do you have aswell ?? What does it chrono at loz ?? Think I pushed it to hard on full auto but at least its shown up the flaws doubt mine will be as good as yours though lol
dex Posted January 13, 2015 Posted January 13, 2015 shs pistons are very good. Light weight and strong. IMHO the best thing you can do is fit sorbo and set the aoe. This helps no end with reducing wear and stress on the gearbox.
n1ckh Posted January 13, 2015 Author Posted January 13, 2015 I was going to do that when the new parts arrive so I'll get a rubber washer tomorow From what I understand, air volume will be reduced and fps aswell but I doubt its noticeable other than on a chrono

Think I pushed it to hard on full auto but at least its shown up the flaws doubt mine will be as good as yours though lol M90 spring, chronos at about 330-335fps if I remember correctly. 300mm barrel, sorbo pad, AoE correction, original TM EG1000 motor and a Gate NanoAB mosfet.
n1ckh Posted January 13, 2015 Author Posted January 13, 2015 Haha, just a bit modified then I dont have a clue what the standard spring is in a g&g raider Now its time to solder in my MOSFET when I open the gearbox again

Probably the motor, gearbox casing and the buffer tube and screw. Yeah, that's about it. Actually the inner barrel is the original but it's been cut down so yeah...not original!
n1ckh Posted January 14, 2015 Author Posted January 14, 2015 75% of mine is original, all I've changed is the motor, grease, shims and now the piston etc, I've also cut my barrel down to about 5mm short of the suppressor ending
