This pre-lightened Rocket Airsoft Piston (SHS OEM) is a good choice for anyone running a high speed SSG or DSG.
Gearbox mistiming (pre-engagement) can crash the piston and/or gear train. A lightened piston accelerates faster, which can eliminate or reduce pre-engagement depending on the setup used. Also, since the piston is lighter, pickup stress is reduced as well.
As a result of these benefits, “swiss-cheesing” or lightening has been a very common modification for many years.
All of the holes on these pistons were precisely drilled with a drill press. This process ensures accuracy, cleanliness, and structural integrity. All of the modification for the piston body has been done for the end user.
Additionally, SHS has shortened the rear tooth to the point where it’s almost gone. This can correct AoE on some gearboxes, but others may require a little bit more material to be removed.
High Speed Piston weight: 12.92
14.5T Piston weight: 15.62
These Pistons are made of Glass-fiber Nylon, which has superior wear resistance and can endure much more prolonged stress than Polycarbonate Pistons.
I recommend Full Metal Rack Pistons for anyone using a high ROF or high FPS build. Even if your gearbox is left stock, a Full Metal Rack Piston will retain its shape and won’t wear down nearly as fast nor as often as most plastic pistons.
