Questions & Answers
Bore up kits are designed for guns upgraded with an M130 spring or higher. In order to take full advantage of the powerful spring bore up kits have larger cylinders and air nozzles, which allows more air to power the BB.
Manufacturer: Classic Army
Package includes: bore up cylinder, bore up cylinder head with double O-rings, silent piston head with ball bearings.
I have heard good reviews on this, however I have never personally used one because of the following reason: I own a TM and not a CA. I do have one question.
I know this says "CA only", does anybody know if this could fit in a Tokyo Mauri M16, if it doesn't, ill get systema, but this is cheaper.

For: Classic Army AEG Bore Up Kit for M16
I put this bore-up kit into a CA M15A4 Rifle. I also installed a Tight Bore barrell, double torque gears, and a 9.6 v battery. I found that I was averaging 20 FPS higher than I was use to with the same spring confguration.
Checked using a CHRONY brand chronometer (hop-up off)
Systema M120 430 FPS
Systema M130 440 FPS
PDI 170 425 FPS
PDI 150 405 FPS
The big advantage to using this bore-up kit is you can get better or same FPS with a lighter tension spring which rreduces piston head impact on your gearbox & wear on your gears. If you want to switch to MEGA FPS you still have the capability.
Hopefully others will have similar results.
My only negative at this time is inability to purchase the piston head and air nozzles seperate from the "Kit". They are of a non-stiock diameter so the stock sizes won't fit.
