||i ordered one of these and it just came in today, and straight out of the box i could already feel just how strong and durable it is. the polycarb body of the piston was significantly heavier than my stock piston, and is much MUCHHH stronger! and as an additive, it comes with a full metal teeth rack, which is made of high quality steel, AMAZING for high speed setups.
i have a jg g36c, and another thing i found that really suprised me was the piston head! its also made out of polycarb, and its well-ported and gets a perfect (and i do mean PERFECT) airseal in my g36c cylinder. my sector gear is shortstroked by 5 teeth, which is ALOTT, so my FPS wasnt that great before.. but after installing this BEAST, my fps skyrocketed back up to atleast 300+, and its shooting at about 20 rps :oo
did i meantion that the piston head has ball bearings? ohh yeahh;)
im not sure how well this will fit into other brands of gearboxes, but it is FLAWLESS in mine. i didnt even have to do any modification whatsoever, and thats why i'm giving this a 5 out of 5. and if you also have a jg gearbox, then i gaurentee that this will work EXACTLY as good for you as it does for me!!
