This is terrible.
First of warranty is negative as you void it if you open the gearbox or do changes to the gun in anyway. From the info I have gotten this weapon needs improvements before it is usable. Including a single only block, mosfet, new motor, 11.1V lipo, etc. On that video AOD posted I could hear the windup time was long, and the single system did (once at least), not fire after pulling the trigger. RoF was good when it first was going. Anyway, my point is many airsofters would void the warranty to get the PDR up to par. Specialy if you are going to use it in a CQB enviroment where you need to use single only.
Further taking into account that many will void the warranty they can’t get spare parts. As you stated, one needs to be a retailer of Magpul pts.
To the review part I applaud this review, looking past arnies forum. There is excessively many reviews that go something like this: “This gun is awesome in every way, only negative I can find is the box it came in is not cool.”
