Still having fun with this gun. I picked it up as a refurb for about $170 shipped IIRC. I wanted a low power high shot repeater in .177 for plinking.
I had the reg'ed bottle for YEARS sitting in the closet and kinda bought the gun to use the bottle, but this gun has a reputation and seemed to be exactly what I had in mind.
I set it up and shot it a little but the O-ring in the bottle's check valve was mush from age so the gun was down for a repair. Once I discovered what the problem was it was an easy fix. Back up and hammering away.
After a few tins the bottle failed again. I've been pretty busy but missed this gun so much I made some time for it this weekend. This was the first regulator disassembly I've done. Turned out to be easy enough and with a new O-ring I was back in business.
I've been shooting it with a peep but wanted to try a scope. I was looking through the closet and was looking past a silver .22 rimfire scope that just wouldn't do. I decided to make the gun a "Franken-gun" and mounted up the ugly, cheap scope. You know, sometimes in life things just go right. The gun was dead on without adjustment.
The gun is cobbled together from the parts bin but it's a real treat to shoot delivering 8 magazines of 8 shots with an ES of 20 fps using only 1200 psi. I don't want to fill this old bottle with too high a pressure so I shoot it from 2200 down to 1000 psi. Makes an 80 cf aluminum tank VERY useful. I ran the calc on it and forget exactly how many fills but it was plenty!

710-720 w/Barracudas, 740-760 w/8 grain. If I had a new regulated bottle I would probably get around 12 magazines from a 3000 psi fill.
I may up the power, I want 16 fpe, but if I can't get it from this setup up I'm going to leave it as is. I'm having fun doing this on the cheap. The Hammerli barrels are GREAT so it is a satisfying gun even at low power. These can go WAY up in power if that is what you desire. Starts to get expensive though, and sometimes you are knocking on the door of guns that may be a better choice IMO.
People complain about the trigger and it's usually the first mod owners do. It is a pseudo 2 stage with the first stage not moving the sear. There is a cheap mod that turns it into a true 2 stage but I like it as is. I take up the spring slack until it stops at the sear and then get a light crisp break.
P.S. They are surprising loud too. Maybe I've just been shooting sedate guns too much lately.
Sounds perfect for a high shot count backyard gun the way you have it set up. Add a TKO to it and it would be neighbor friendly as well. The trigger sounds like it isn't too bad, but if easily modified it may be worth doing just to improve accuracy even more.
Doesn't make sense to spend too much money on going the extreme power route, since then you take away one of the most appealing aspects, the low cost.
I don't think the trigger affects accuracy in it's stock form...

and the most popular trigger mod is free should you feel it's needed.
Look for a used one all setup up on the classifieds or watch Airgun Depot for a refurb.
Again, with a newer bottle, I would prefer it in the 15 fpe range(.177, higher for .22) with the same shot count. Even at this power level, w/Barracudas, in this barrel, with the scope, I wouldn't want to be a pest annoying me in my yard.
