    Default Echo 1 PSR problem

    Very inexperienced tinkering with bolt action springers so my parts terminology will be off. From what I've read online, it's essentially a JG bar 10.

    It's had maybe 70 rounds through but even early on it had an issue where I'd cock it and the trigger wouldn't move. After a little jiggling it would fire. Now when I pull the bolt back it slams forward immediately so the piston isn't locking into compressed position.

    Gonna start tearing into it soon but unfamiliar with parts/names/overall function. Any ideas what happened/what I'm going to find when I get in there?

    Your sears are worn out. You can fix this buy either buying a new set of sears/piston or buying a 90 degree zero trigger/piston.

    This is a very common problem with stock bolt action rifles. I would suggest the zero trigger/piston route. It will only run you about $100 for the kit off evike but will be able to withstand 550+ fps for thousands of rounds.

    Yeah, the standard trigger parts running anything over 400 fps will really only last for a few rounds. The 45 degree trigger system is a terrible system for high fps, good choice on the zero trigger.

    My 98k is about 10 years old with probably 10k rounds through it at 550 with a zero trigger and it's still kicking.

    Yeah i believe the compressor is kicking on and off. Its random tho which makes diagnoses hard. I checked all the switch wires and seem to be tight.
