Air Arms Owners Club

I have an S510 Carbine, unregg'd.
Average ft/lbs 10.45.
In monkey language please, is there a link or help here to push this up nearer 11.5 myself as a 1/2 competent DIY'er? Or is this a job for a gunsmith?

my advice to you is: if you don't know what you are doing, leave it to someone who does. cylinders/compressed air, and highly compressed at that! could mean you never get to try again. if you feel you are competent enough, and you need to be, youtube should have enough content. having said that, not all youtubers are competent.

I agree with Gary, depending on where you are based, there might be someone near you to show you the ropes with your rifle, saying that, they are very simple to work on, once any antitamper is removed. Rog
