PolarStar Airsoft PR-15 V2 Gen3 Fusion Engine Electro-Pneumatic Gearbox Kit (Model: EMG Edition Black Nozzle)

"great product. only gripe i have about this is that it doesn't work with ambidextrous selector models, you'll have to use single sided selector only.

"Best engine. It mentions that it can go up to 30 rps but I got mine at 33rps no problem. Super fun and I got the 115 s/a which is really lucky. If there were a zombie map I would use this.

"Obviously these things are known as the creme de la creme of airsoft and they are known that way for a reason. This is my fifth Polarstar fusion engine and every single one has been a pleasure. I have installed the V2 G3 into bodies like Krytac SPR Mk2's, King arms TWS M4's, and many more without many issues at all!

"Got this and put it into G&G ARP556 and it’s absolutely ridiculous how much fun this is! I couldn’t be happier! completely exceeded my expectations. Although pricey it’s equally worth it! Of course Maxx hop-up with 6.01 inner barrel and bucking is a must as well keep that in mind

"Just as everyone else has said, this thing is a beast. I don’t wanna be redundant, so all I’ll say is that it dropped into my Ares M110 with ease. Now I have an absolute monster DMR, this is a must for anyone who plays the marksman role. And it’s pretty damn quiet, making it even harder to locate your position. It’s pricey no doubt, but 100% worth the money. Plus it’s resale value holds pretty well, so no harm no foul.

"If tuned properly with good upgrades this can make any gun the best on the field.

"i have a question does it com with an fcu?

"This is just so OP!!

Pros:
Instant trigger response
no cycle time at all (ultimate spam cannon)
I got mine shooting up to 80 rps
shoots accurate (with h hop maple leaf bucking and tight bore)
just so much better than any other system

cons:
I have mine in a g&p body. It fits but the selector plate and switch doesn't work that well but I don't mind to much

"PolarStar is truly the most advanced, state-of-the-art, on-point performance in Airsoft today. I've built several PolarStars, mainly in VFC and G&P bodies, and they perform amazingly well.

What's great about PolarStar: (1) smooth, instantaneous (and incredibly satisfying) trigger response; (2) control and adjustability via the Fire Control Unit; (4) no maintenance, no hassles, ... simple and easy to use; and (4) USA made. I've actually been to the facility in Delaware where they are built, and the guys who make them are really excellent people. It's as immaculate a factory as one could imagine - they excel at fabricating high-precision metal parts.

I've been through the gamut of other types of Airsoft guns, first GBBR then AEG, and PolarStar is clearly the best overall experience. Between the unit itself, the tank, the air line, etc., it more expensive, but as others have said, P* is worth every penny!

"If you're looking to buy this, definitely do! It is the most reliable system for airsoft I have used and this Gearbox will fit is almost ANY AEG M4. Please note: when you buy this it does not come with a regulator, a QD (Quick Disconnect) Male connector), a tank, or a small LiPo battery. It does need the battery, just in case you were wondering.


Pros:
Easy to install
You can still use Mid-caps and Hi-Caps
Lightweight
Controllable FPS and RoF (With Air adjustment.)
Intimidating sound
Extremely accurate (Even with a stock barrel)

Cons:
The price (But its worth every penny)
Selector plate needs to be modified for a G&G lower.

"This is THE most amazing gearbox.

"Best Setup I have ever owned and ran, No more Gearbox Maintenance! Fully adjustable FPS, tons of settings so you can tune the way it shoots via FireControl Unit.
Trigger response is amazing,and the install took me 5 minutes!

Invest in this and save yourself potential gearbox breaks, and maintenance fees!
I know many people that ponder about having to get your tank filled and carrying the tank on your back, I have a scuba shop that fills my tank for $8 Bucks and if you get a 4500psi tank carbon fiber material it lasts you a LONG time and its practically weightless caryring!

"Best possible thing you can buy with your Airsoft money. Performs flawlessly and you don't have to upgrade it and maintenance is super low almost none I suggest you buy this now!

"This gearbox is amazing I'm already hittin 400 fps with a rate of fire of 100 bbs per second!!!!fun!!!

"Best. Investment. EVER!!! This has outlasted EVERY SINGLE GUN i have owned. This can be a sniper, a smg, assault rifle; This can be ANYTHING!! 10/10
