"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.

"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.
by Andrew V. on 10/02/2017
"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!
by Grace G. on 10/02/2017
"This gearbox is amazing I'm already hittin 400 fps with a rate of fire of 100 bbs per second!!!!fun!!!
by Farhad J. on 10/02/2017
"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
by Josh K. on 10/02/2017
"Wow. Just. Wow. Polarstar, I would like to thank you for, well. Everything!
This thing is amazing. I couldnt ask for more!
Just to give you a background on me, I have been a technician for a few years now, I have setups ranging from 400fps @ 40rps to 600fps @ 20rps, and this thing can beat all of them with the swap of a nozzle and a few seconds of changing the FCU.
Now this can be used as a great advantage, or in a very horrible way.
Please abide by your fields velocity limits and DONT give all P* users a bad name!
Another thing that many people dislike about P*s is the need to carry an air rig.
Let me dispel that myth by just saying that you barely notice it.
I use a camelbak hydration system and it works great with the Ninja tanks.
The air rig itself feels like a sling and barely gets in the way.
I see a ton of compatibility questions here and I would like to answer them:
1) Will it fit in TM, VFC, King Arms, A&K, G&G, JG, CYMA, G&P, Matrix, AIM or other TM spec bodies?
Yes.
2) Will it fit in a ICS split body?
No
3) Will it fit in a KWA?
Yes, but not without modifying the body. KWA body's are not to TM spec and you will need to do some sanding. Pain in the but, but it can be done.
4) Will it fit into other V2 gearbox guns?
Yes, It will fit, however it will not function/feed correctly. You will need selector switches as well as P* nozzles specific to your gun (IE like a G3 or similar)
Polarstar is working on getting them out, so eventually it will be a yes :)
How does it work?
1) Pull out your standard V2 gearbox
2) drop this in.
3) profit beyond everything
The Polarstar engine is a quantum leap in airsoft mechanics.
By utilizing HPA and solenoids, and eliminating the many parts that break in a standard gearbox, you get a system that literally, by definition, CANNOT break.
Trigger response is literally INSTANTANEOUS,
you can adjust RoF anywhere from like 8rps to 70rps,
FPS can be adjusted by changing the nozzle, (easy thing to do, takes 2 mins max)
You can also adjust how much air the engine pumps out of the barrel, which means you can actually utilize a 700mm+ barrel effectively, while in a standard AEG it is normally impossible, even with boreup kits and such.
Pros:
Everything
Adjustable ROF
Adjustable FPS
Adjustable airflow for super long barrels.
Instantaneous trigger response.
Programmable burst mode
MADE IN THE USA!!!! BEST OF THE BEST!!
Drops in almost any standard M4 body.
extremely consistent, literally +-2 FPS deviation between shots at max (with a good hopup/bucking combo)
Cons:
$$$ Cost
Air Rig is extra
Tank is extra.
Overall, this is the best airsoft system on the market.
Polarstars can run insane setups without any stress on the system (Google P*'s 1,000,000rd stress test)
The initial cost of the system can seem like a turn-off for most players, but the thing is, if you have nice $400 base gun, you will have to pay $100 to get it to a 400@40rps setup, plus maintaining the darn thing will cost at least another $50 every few months when parts break and stuff, so over time it will save you money if you run high ROF or high FPS setups.
Its worth it. Trust me. Getting another for my AK once I can afford it :P
Again, its totally worth EVERY SINGLE PENNY.
