I love mine to death. If you buy one brand new, tighten the ejector screws and lube it then your gtg. If you get an older used model (Like I did ) do the same and check for pierced primers. If you have them, you need to get your firing pin hole in the bolt face chamfered. I did it myself in 2 min with a dremel tool.
The gun is 100% reliable now. Smooth and accurate. Don't forget on the XCR plus side that we have the adjustable gas valve as well. It is nice to be able to modify your gas piston settings to go along with your ammo. Wolf is super low pressure, Win white box is medium and AE is high pressure. You don't want to eject your brass too hard or you may dent them. (Bad for reloading).
The ergonomics are better than any black rifle out there and the build quality is excellent. Great machined aluminum and steel. They had some QA issues to start, but they seem to be pretty much fixed. Easiest disassembly and cleaning too.
Mine is 100% reliable and have yet to have a failure to feed, fire or eject. Go get yourself one while the US still lets you.
As for the PE90 being more accurate. I would like to see the proof of that. Handload to handload and commercial to commercial ammo. What sources do you quote, or is it just more anecdotal " Its more expensive so it must be more accurate.
