I wasn't all to thrilled about my trigger (I'm spoiled by Jewell BR triggers andseldom thrilled about any productiontrigger)... so a bit of a "touch-up" was in order.
I've reworked a few hundred triggers in my time, and I can tell you that thisparticular triggeris nothing fancy or complicated, but I suggest to anyone attempting to repeat this process, to mock-up the trigger as I've done so you have a good understanding of how it works and where the contact points are.
Rifle blown apart.
Trigger blown apart.
Trigger mock-up engaged... areas of contact.
Trigger mock-up disengaged... areas of contact.
All I did was lightly stone and polish the areas of contact to remove machine marks. I didn't change any angles or alter any relationships by more than .0005". It's actually a easy trigger to touch up if you have a good eye and fine ceramic or diamond stones.
Just remember, taking metal off is easy, putting it back... not so much.
Disassembly and reassembly of the entire gun is pretty straight forward. You will need a spring compressor tool as the stock spring has a good amount of preload.I got a very nice wooden one from VPilot on the "Yellow" for about $80.
The only trick is getting the sear lever and spring back in... and it's really not much of a trick.
Put the spring into position first and slide the pin in just enough to hold it... then insert the sear lever under the hook on the spring, insert the pin the rest of the way and rotate the lever forward.
Top view... sear/spring detail. Note the relative positions of the spring hook and forward arm of the spring.
The lever is held down by the sliding automatic safety plate... the safety catch lever is permanently staked to the trigger housing and the tab on that lever engages a cutout in the sliding automatic safety. The whole thing needs to be held down firmly to the groove in the endcap as you reinsert it into the receiver.
So how did it turn out you ask?Trigger pull adjustment range is now adjustable from roughly12 oz. to just under 2 lbs. Feel is extremely smooth andsear release isclean and crisp. Travel is still what it is... but the idea was to take all the gritty feel and crunch out of that travel. I have to say it was a rousing success and well worth doing.
Ifthisis something you'd rather not attempt,talk to Gene Curtis (he owns this forum and airguntoys.com)... he did the trigger on the Fusion that thebookdoc now has, and I'd imagine he did something similar to what I did.
