Ok, so I'm going to start with a jg bar 10, and upgrade from there, this will be my first project. I initially decided on all the parts and was going to get an m170 spring, but then I thought, maybe I could even get an m190, though I thought the stock trigger wouldn't hold up with it. Therefore my question is would an m190 spring along with this trigger-piston combo workout ok? Also is the difference between an m190 and m170 that noticeable and worth the upgrade.

Heres the trigger: http://www.airsoftgi.com/product_info.php?...roducts_id=9273

Ok, so did some more research and I've been told that the ASGI parts are not trustworthy. So here is a list of parts I want to put in my JG Bar-10, how do you think it will perform, and will the laylax parts work with the PDI? I also list two zero triggers, one is much cheaper, is there that much of difference in quality of the piston included or is it just cheaper because of the site?

Laylax m190 spring: http://www.airsoftatlanta.com/Laylax_VSR_1...63.htm?CartID=5 (I know 190 will shoot very hot, and too hot for many fields, but I still want it)

So yeah, there you have it, just wondering some opinions on those parts as an upgrade, thanks.

Well, decided to propose this idea, maybe get some feedback on going full laylax. so here goes nothin

Well, how do you think that would all work out? Also I take it I should be getting an upgraded hop-up bucking so if someone could possibly suggest a specific one, that would be awesome and a ton of help. Thanks all.
