Swede M94/96 bolt overriding sear

Roverguy said:

All of a sudden, I have this issue.

One of the M94 carbines imported pre GCA with the 1.5” sleeve pinned to the muzzle that Bubba got to before me. Timney trigger. As you know, these are cock on close and depend on the cocking mechanism in the bolt catching on the sear as the bolt is pushed forward. It ain’t.

Anyone have experience of this and know the fix?

Thanks.

That replacement trigger may have a Sear Engagement adjustment. If it's set to "light" it reduces the height of the trigger to catch so it jumps. Find out what model trigger it is and look for the adjustment instructions. Don't just play with it. You may get it to catch but drop when the gun is jarred causing it to fire. Very dangerous. Good luck.

What else did he "bubba"? Is it posible that he messed with the sear surface, damaged the Timney trigger, or both? Most of the 94/96 guns were in very good shape when imported.

I've got the same issue with a '93 Mauser that I converted to 7.62x39. I installed a Timney trigger and now the cocking piece can over-ride the sear about 1 time in 5. A close inspection has shown that the 100+ year old cocking piece has worn to the point that the bottom edge of it's engagement surface has become rounded. I ordered a new (actually old, but unused) cocking piece, and will install it tomorrow. On any Mauser the sear should hold a cocked bolt even while the butt of the rifle is bumped hard against the floor. Also, a screwdriver wedged between the tang and the cocking piece (with gentle but firm effort) should not be able to lift the cocking piece off the sear. Having proper sear engagement on a small ring action is especially important because small rings do not have the engagement surfaces on the front shoulder of the firing pin like on a 98 action, that prevents a discharge before the bolt lugs are fully locked. If the cocking piece slips off the sear on a small ring the rifle could discharge before the bolt lugs have locked up. Not a good situation!

Ditto on the testing of any trigger. Any time you mess with triggers on any gun, or get a new specimen you should give the gun a firm“bump test.” Never a bad idea. Pm me if you need a new cocking piece, I have a spare. Hopefully your trigger just needs adjustment.

The 94, 96 and 38 all use the same cocking piece/sear, if it is messed up order a new one from maybe gunparts.com otherwise adjust the trigger’s engagement sear to hold properly. A Timney trigger for the proper Mauser should, as factory new, hold fine, unless a Bubba got into it or perhaps put in the wrong model Mauser trigger, like a 93 trigger in a 94. A 93 trigger guard and trigger will fit, but not work. I bought a parts gun like that is how I know.

Watch the ATF and sleeves with pins, they do change the rules.

A rubber mallet does wonders for safety testing. Someone right here recommended it when I was having trouble adjusting the trigger on a rifle. Gotta pass the mallet test.

You might want to add: Hit the butt stock, not the trigger.

Excellent point.
