I did mine year or so ago got spring and seal from JM, ill have a look and let you know part numbers. Will tell you now they are a bear to cock, i clipped spring on mine and its still shoots a 15g jsb at 880.David
Well, I ordered one yesterday. I hope I get a good one...
You can change the trigger for a charlie trigger , I warned you thats its tough to cock. David
I’ve got over 200 shots thru it now & it’s becoming a decent shooter. And I’m getting muscles back too. Trigger definitely needs improving. It’s cold here in Wisconsin, so shooting isn’t too often. The gun really likes FX 15.9g & JSB 15.89 jumbo exact pellets. I’m happy with this Gamo.
I bought one almost a year ago. First one had the most beautiful beech stock I had every seen, But someone got heavy on the sanding belt and gouged it pretty bad. I got it exchanged. Second one was perfect and stock still looks awesome for beech. I swapped the trigger adjustment screw and have had no issues. I bought the Extreme Pro after buying a Swarm magnum gen 2. For magnums they don't seem as hold sensitive or as hard to get great groups. Under a dime at 25 yards with magnums is dang good with just a causal springer hold. Took me hours to get the hold right on my Hatsan 125 sniper to get a decent group.
