stock on/off (I just don't like them)
clear eye plate
Price - coming in at about 750 the price for what you get with the PM8 is the best in it's class for price to performance.
Frame - Stock UL frame, so it'll take any UL frame boards, I suggest the Virtue board.
Lite - I weighed mine on a cooking scale and it came in with a CP on/off (a tiny bit heavier then the stock one), reg, stock barrel and stock board with a battery came in a 2.1 lbs so with the stock on off I'm guessing it's be just a hair over 2 lbs
Fast - the stock board/frame being UL makes it a fast marker that you can adjust Max ROF and 4 different firing options with the 2 different adjustment screws making it easy to adjust to what you want in a trigger
Stock Boards - to me the stock trigger/switch seemed SUPER heavy compaired to my PM6's even with a CP trigger it still felt way to heavy, I switched to a Virtue with 20G switch to make it feel smooth I added the spring back in to make it feel like I'm pulling a trigger.
Stock on/off - I just don't like the stock on/off so I went a head and swapped it out for a CP, more personal preference, the stock one isn't nice for larger fingers in my opinion.
Eye Ribbons - to use the eye ribbons with an aftermarket board you need an eye adaptor. the ribbons brake pretty easy on them and you have to dremel the frame out to get wired eyes to fit.
I've had a run of problems with bolt stick and some tiny LPR issues with my PM8. I also broke the eye ribbons and wanted to switch to wired eyes but there is almost no room for them. I dremeled the frame and they work now but it's still a pain in the but with the lack of room to fit all the wires and such.
awesome marker for the price I love my PM8. If it had wired eyes and a better stock switch I'd easily give it a 9.5
