Barrel extension/fork slightly bent

Luddite08 · 04-13-2026, 12:48 AM

Hello all,

I have a 1936 Mauser with a slightly bent in fork. It still cycles okay by hand, I haven't shot it yet. To reinstall the breach block I have to slightly spread the fork. Once installed the breachblock does not slide smoothly, as the bend in the fork pinches it slightly.

I found two great posts on this subject, and am waiting on a caliper to measure the fork and see exactly how it is bent, twisted or misaligned.

I'm wondering if anyone can perform the slight unbending service for me, or if anyone who has had the same issue could share their experience and what they did to resolve the issue.

A Google search suggested using a lapping compound and sliding the breach block in and out of the fork. This seemed like a good idea until I took a look at the breachblock and fork rails, the breachblock rails are not flush with the fork rails.

Thanks to all on the forum, I've learned a lot from reading on here!
