TM M14 450fps-what parts do i need?

[Hugo03]

I am looking to upgrade a Tokyo Marui M14 to fire semi-auto at 420-450fps. At the moment all gearbox parts are standard, but i have a 9.6v battery already. Could anyone tell me what spring i would need and what gearbox parts would be needed to cope with the extra power(bearing in mind it will be locked to semi-auto)?

Steel Bushings, Systema M130 Spring and Metal Spring Guide would cut it as a minimum. Id advise getting a steel Sector and Spur Gear.

TM gears are thin, if you really want to be this as a DMR, buy thicker gears, stock TM gears wouldn't stand a chance, Type 0 cylinder, and a tight/precision barrel (6.01 or 6.03), SP120 spring, spring guide with bearing, piston head with bearing. High torque motor. i wish this could help.
