Thread: Bubba what have you done?

Bubba'd Swedish Mauser trigger I encountered when checking a mate's rifle when sorting out another Swede for him.

Worst issue and fatal issue; sear ground away too much and at too acute an angle that even with the take up screw removed the rifle would go off if held 15cm off the ground and dropped on its butt. A very unsafe situation.

Second issue; Swedish Mauser sear bars and sears are case hardened. Taking this amount of metal off removes the hardened layer and now the surfaces are soft. I suspect someone tried to re-harden then temper the sear bar (blue temper colour mentioned below) which doesn't work with case hardened parts. You may be able to see in the second photo that the sharp edge of the sear is already rounded over and worn and a flat has worn into the top of the sear. Potentially this trigger was safe when first modified and with the wear due to now soft steel became unsafe.

Minor issue; trigger interlock stud being ground off means the trigger can be pulled when the bolt isn't all the way closed. Swedes are unlikely to go off out of battery in this situation but still not the best thing and might give the primer a bit of a slap none the less. Feeling lucky?

We decided it was best this trigger was removed from the rifle and rendering the rifle a non functional barrelled action with a bolt (unmodified) that can be used for parts. He has three Swedes, so now after a bit of parts swapping he has the two best barrelled actions fully functional and the one with the worst barrel kept as a parts gun. The bubba'd trigger will never be installed on another rifle.

Rudimentary screw and welded on extension to the trigger to take up the first trigger stage. Note the blue temper colour on the spring housing of the sear bar.


Sear ground too much and far too of an acute angle.


Trigger interlock stud ground off.
