Good day all,
I've just brought three cheap air rifles of the internet with the idea of seeing how much I can tune them up. I received the crosman/benjamin first and was quiet impressed with how hard it hit but poi was all over. I finally opened her up this weekend to see what I could see and found the two coils where broken off on each side of the spring (I'm surprised how hard it was still hitting but know why poi was all over and why she felt so rough) Anyways started ringing around today to try and source a new spring seals etc. I've got abit of a problem in that no one knows the model and I can't seem to be able to convince then to go count coils, check wire size etc. So my question is does any one know what other make/model spring will fit this gun?? the broken coil has 42 coils, 3mm wire. I haven't measured id or od or total length yet would this help if so I'll post that info asap
Thanks for any help
