Hey sorry I didn't get back to you, there's been so much activity on the boards lately that I didn't realize you'd posted. Thanks so much for pointing that out, it saved me
I just used the L96 at a game, and I'd been doing some target shooting to get her sighted in. 500 shots fired perhaps, and still working great (in fact, I was literally the hand of god at the last game--assassination missions galore, and once I had the rifle sighted in I barely missed a shot). At least I know that those mods (which I've been doing the past few months but haven't had a chance to test without a trigger group) worked like a charm.
I'm using the UTG stock trigger and the PDI trigger sear. I got the sear off of airsoftatlanta.com, and I didn't bother to replace the first sear or the piston sear, and everything's working fine. I'll let you know if/when it breaks, but I'm very happy with this. Especially because I can actually replace parts when this breaks as opposed to the zero trigger, which gave me nothing but trouble once that small spring broke.
I ordered a backup UTG trigger as well, to replace parts other than the PDI sear when they eventually break. I never fired a single shot using the stock trigger sear so I couldn't tell you how that will work for you. In a 45 degree trigger system the trigger sear takes the most stress, though.
