    "This set is great if you're looking to replace worn down old parts/ achieve better compression and get fresh parts in your gearbox. This is by no means a tune up/upgrade from anything beyond a stock gun. The spring this package comes with...just toss it straight in the trash. It's flimsy & over the course of 3 days resting in my gearbox, it had already showed signs of being compressed, just from sitting in the shell. The spring guide included didn't fit my gun, but I can say that while it is an upgrade from stock, I wouldn't consider it a built to last part. If you already have a metal spring guide, just keep the bearings on the piston, and use the stock spring guide. Now for the good stuff: All of the other parts are beautiful...but over priced. The gears, cylinder, cylinder head, piston, piston head & air nozzle are all re-branded ZCI parts. They're all beautiful and built to last. You could trust these parts, aside from the standard gears, even in medium-high stress builds. All in all, to buy the gears and other parts separately, it'd cost you $4 more, so you're still getting a deal. No way I'd pay the non-sale 150% mark up price LOL. If you're looking to replace old dying parts without extensively upgrading, BUY THIS. If you're looking to build and not using the included gears, I'd stay away from this. 3 Stars for the lemon spring and the rebranded parts.

    "I have been using this kit in my Classic Army M15 for about 4 months now and it has worked out pretty well so far. The only issue I have with the kit is the grease that comes with it does not have much and it does not come with shims which isn't that big of a deal anyways. Also the stock CA motor would not pull the M120 spring so I have an M100 in there right now and it shoots about 340-350 fps. Overall a pretty solid kit for the price especially because I got mine when it was a doorbuster for only $50.

    "Great kit, but one thing of note. If you don't have a high torque motor your going to need one to pull the M120 Spring. A stock motor won't even budge it.
