First, a big shout out to Fang for doing this project. Gun was low on power (15 fpe) and making grinding noise when cocking. First a call to JM for parts. A Zrt spring, breach seal, apex seal and set spring. Fang polished all parts, trigger job, removed front sights, made/installed feeling muzzle brake and buffed out stock. Totally amazed at the outstanding quality of work Fang did on this one. Very happy camper. I put 350 pellets down range in 2 days. Got her zeroed @ 45 yds. Shooting jsb 10.3 @ 875 for 18 fpe. This sparrow taken @ 45 yds headshot. Just punished spinners out to 70 yds after zero. This one a real shooter. Again, many thanks Fang.
