Epic high rate of fire G&G GR16 Custom Airsoft gun

Описание: This gun is putting around 340fps at about 50-57 rps depending on my shitty 1300 mah 15c 11.1v Li-po's battery charge. Around 40-45 on my 2200 mah 25c 7.4 v li-po

Parts:
ASCU V.2 Smart MosFET (you need a MosFET for a build like this)
SHS High speed motor (enough torque to pull a M150 on standard G&G gears and 11.1v Li-po)
Modify quantum double cycle gear set (too cheap to buy the Siegetek, RiotSC ones)
Echo 1 super light full metal teeth piston (Really good, same as the Azimuth piston)
Stock G&G high compression piston head (very good compression)
Stock G&G ported cylinder
Stock G&G cylinder head (again very good compression)
SHS Aluminum o-ring air seal nozzle
4 SHS Stainless steel bushings used on the sector and spur gear (shimmed perfectly)
2 G&G Stainless steel oil less bearings used on bevel gear (shimmed perfectly to pinion gear)
Stock Tappet plate cut to 11mm for the DSG
SHS m120 spring with spring guide spacer
Stock G&G ball bearing spring guide
Stock G&G 363 mm 6.04mm tight bore barrel and Hop-Up (pretty good accuracy)
Stock gearbox shell reinforced with aluminum tape around the front (gearbox starting to crack)

Faucet washers on cylinder head to help Angle of Engagement and absorb shock. No Swiss Cheesing yet done on piston.

Having compression issues on full auto. If you know why tell me in the comments. Tried everything, not the barrel length, nothing but seems that the nozzle isn't coming back fast enough though i tried to cut the tappet spring to make it stiffer but didn't work. It feeds fine.
