Well, guys I decided to purchase some extra parts for the 4 COMETA rifles I currently have, I have been looking at the TITAN #12 spring as a replacement spring for my rifles, ARH no longer sells springs for the COMETA guns, but JM still offers piston seals! and I just purchased 4 more from him, buy them while you can if you want them Jim is pushing 80"s in age, so he won't be around forever! The TITAN springs are made of SWEEDISH steel! IMO you're not going to buy better spring steel IMO, 2 of the springs I ordered showed up today, after looking at them I purchased 4 more! from the Country Store out of England, 4 springs cost about $103 U.S. to my door! that's cheap! for good quality air gun springs!
Nope! their a full power spring! The factory spring for the 400 series is 36 coils of .120dia wire, the TITAN spring is 36 coils of .115dia wire, now just my thoughts here, were talking about 2 different spring makers, I can just about Guarente the TITAN, but I could be wrong about this? because it's made of SWEEDISH steel it may not need the .120dia wire to achieve full power? and even if the TITAN doesn't produce the power of the factory spring? it's going to last a whole lot longer! and give a smoother shot cycle if tuned correctly IMO, Here's the kicker, the TITAN spring #12 is supposed to work for the COMETA 100, 220, 300, and 400 series rifles, it is very obvious this spring is not going to fit my 220 compacts! it about 6 coils to long! so, I'm going to have to cut the spring to make it work in the smaller tube size COMETA rifles, but it should be a direct drop in fit for a 400 series rifle! the Packaging says its a full power spring, and warns about making a U.K. gun over the power limit! and for $20 dollars a spring I don't care! I probably going to detune my new rifle at some point to 12ftlbs or less any way! Because I do not need any more power than that! people way underestimate the power of a 12ftlb spring gun!
buy them while you can if you want them Jim is pushing 80"s in age, so he won't be around forever!
