"I have sets of their AK style and M4. The head is a freaking pain to get into the cylinder but it means that it’s a perfect air seal there.
The POM (and the o-ring that comes with it) also create a perfect air seal.
I know the other reviewer mentioned not having an aluminum nozzle, but I’d say it’s better to have plastic. However, I’m also not running high-stress DMR builds. The plastic has been great for my high ROF 350fps setups and my 400fps setups.

"Great upgrade set with really good airseal without any fuss. Just make sure you use enough lube when assembling and you'll be singing while the enemy runs or perishes. The parts are well machined and seem to fit most, if not all, makes of gearbox. They even fit is gearboxes with tighter dimensions like LCT. The piston head is probably the best part of the whole thing. It's light weight and can stand up to M150 springs and possibly even M170s. Just be sure to use a sorbo pad with it though (not included) as it's POM and will explode on you if you don't.

This kit is deserving of 5 stars, but the only thing holding it back in my books is the nozzle not being aluminium. Not a necessity but just gives me the illusionary piece of mind that the gearbox is stronger.

Definitely worth a buy if you're looking to upgrade your gearbox.

"Mine didnt come with a nozzle and the head doesnt fit into my standard CYMA gearbox. Overall not worth buying
