If you have not seen a Polarstar PR-15 in action, you must. These guns are simply amazing and to quote myself, represent a "quantum leap" forward in airsoft technology.
Let me start with the rate of file (ROF). 30 rounds per second. Are you kidding? Until you've seen that kind of ROF it is hard to imagine. The PR-15 can literally be used as a fire suppression weapon because it spews bbs at a simply amazing rate. Only issue is, you better have lots of mags that feed well (although if they feed slow that's ok too, you can set that in the FCU). At that rate (which may not really be optimal, but can be set with the FCU) you'll empty a mid-cap in under 1.5 seconds. I use high caps and use a lot of trigger control.
FPS - Here again Polarstar is WAY ahead of any AEG. Out of the box, with the blue nozzle, your at 400+ FPS. Try a sliver and your +/- 500. Red, fuggetaboutit. All this is controlled with the 2nd stage of the air intake system. So you can dial in your FPS for CQB or sanctioned fields on the fly. Total control of +500 FPS?? Good luck getting that with an AEG.
Range - 200+ feet is no issue. Set the hop up, you can probably push 250 - 275 feet no problem.
Fire Control Unit (FCU) - Here's where it gets interesting. All the PR-15's fire controls reside on software on a chip which has a tiny LED screen and joy stick. You can set the software to control everything from ROF to dwell to open/closed bolt to settings for slower feeding magazines. Revolutionary!
Quality - I own several KWA, Echo 1, G&G, ect and I know several guys with Systema AEGs. I'll keep is short and say the Polarstar has virtually no moving parts (no motor, no gearbox, none of the crap that always breaks) and the parts it has are 100% Made in USA of the finest quality materials. The Polarstar team seems obsessed with perfection and that's what you get. You will NEVER have to worry about microscopic parts again. Even an idiot like me can service the Polarstar.
Customer Service - These guys can not be beat. They will promptly and gladly answer any questions and will correct any defects. These guys are airsoft gurus and they know what players demand on the battlefield.
Value - Are these guns expensive? NO! Here's why. In order to get an AEG anywhere close to the Polarstar's performance, you'd have to invest a minimum of $700 - $1200. You'd need to have every top-of-the-line part professionally installed and tweeked. Then have fun keeping them tuned and not exploding. With the Polarstar, you already have the best of everything out of the box. Why would you buy a Systema for $1500 which will still need another $1000 worth of upgrades and still fall short of the Polarstar??
Final comments - This is a game changer. I don't think airsoft will be the same in 3 years because Polarstars's HPA system revolutionizes the game. If I had the money, I'd invest it in this company cause they are going to be HUGE in the very near future.
