Hey guys , I have been doing alot of googling but cant seem to find the length of a mainspring for a b3-1 under lever air rifle. The reason I ask is because I brought a kit for the gun and the spring that came with the kit is waaaay longer than the one that was inside the gun. Now I know you are going to say make the spring the same size as the standard one, but I dont know if it has fiddled with before as it looks very rough and is bent slightly. I have found a few sites and some information but nothing set in concrete. Another avenue would be to email youngs where I purchased the spring from , which I shall do tommorow. Anyways thanks guys. ------------- As long as there is lead in the air...there is hope. |

 Does it look like this, if so this spring from b3 is OK. https://www.pyramydair.com/blog/2018/04/chinese-b3-underlever-part-5/ Also this descussion on them may be useful, it tells how to measure length off the gun itself. https://www.tapatalk.com/groups/yellow/b3-1-22-b4-1-22-b3-1-177-stronger-main-spring-t427931.html  If it looks right get ahold of hasting springs, have a talk to them. They will probly ask you to send it down and make a new one. Stronger or weaker if you want. |
