Just want to know if a metal aps2 trigger box and upgraded sears could handle a 550fps spring( If not 550 then 500 should handle?). I know the zero trigger would be better but I am trying to keep the price low, and it being a 90degree mech stock I was thinking it could handle.

They have them at trinityairsoft.com. That is exactly what I was thinking but did not know if it would handle the strain. I am guessing it would from what you said.

Never saw it there. Helpful link and for 30 bucks most people will buy it.
