hello all, ive searched hi and low 3 or 4 forums trying to find a maccari spring part # for a crosman g1xtreme or similar. all ive found is most gamos use this same action . i think ive found the seal #. the factory spring part # is b18-00-4d. am only looking for stock or slightly smoother performance, not ultra mag scope buster. any help is greatly appreciated
G1 is same action as Quest, Summit, Gamos. A Maccari e3650 will give you a smoother shot than the stock spring which I bet if you pulled it apart you would see a kinked spring. I used the e3650 in my Big Cat with excellent results. I think I also used the Small Apex seal.
I also had a few Tarantula springs laying around so I put one in a Quest I'm working on right now. WOW. It took CPLs from 840 stock spring up to 1150 fps with the Tarantula. I will end up shooting CPHs with this thing!
I don't know the exact specs but I do know the Tarantula uses a much bigger diameter wire than the e3650.
