I really hate modding these lever action blasters. I found a broken SlingFire at Goodwill and fixed it once. It worked alright. Then I opened it again to replace the catch spring because I didn't use the correct one. Unfortunately that means having to remove the gearbox and bolt sled. I thought I had put everything back the way it was before, but I guess not because now the bolt violently slams forward during priming and the plunger doesn't catch.

Reading UncleNumbers' document, I guess it has to do with the clutch spring. Beforehand, I removed the spring-loaded catch that interfaces with the rack, which I guess "saves" the bolt sled's position when you prime it and prevents it from moving backwards (kind of like a half prime except it engages with every tooth on the rack). But since I removed it, the only thing that prevents the bolt from coming forward is the lever's gear, which, according to UncleNumbers, won't work if you push too hard. I removed the catch on my actual SlingFire with no issue. It actually runs smoother that way. But for some reason, I guess this other SlingFire didn't like it.

I gave up on it. Good thing it wasn't my actual SlingFire.
