BIT: Making a K31 bolt

Post by Fill »

I have a couple barreled k31 actions that I want to build. I also have a machinist friend who could make exact copies of one of the 6 other bolts that I possess.

If he doesn't charge me for the parts, and I don't sell the parts, is it illegal to make the parts?

And if I use a headspace gauge and a reference bolt, can I set the headspace by adjusting the thickness of the bolt's face?

It's a non serialized part. No Type 7 FFL required. He could take dimensions, start manufacturing and sell them.

I thought I might run afoul of some patent or licensing laws.

? All my bolts have serial numbers on them. I know that Swiss military armourers were issued with replacement unnumbered bolt kits for trial and fitting purposes, but they electropencilled a number onto the bolts once they were mated to a particular receiver.

Do you mean that in the US, there is no legal requirement to number rifle bolts?

Fill, you might find it hard to get a 7.5x55 headspace gauge. I think you would have to get one specially made from drawings. I might have those somewhere... Since you can't simply rotate the K31 barrel to adjust headspace (because of the cam cutouts), I suppose adjusting the bolt head is the way to do it. IIRC, the 1889 and 1911 bolts had removable head-pieces for that reason.

I think what he means it is that a bolt is not a serialized part according to the ATF and therefore not a gun. So one can crank out as many as they want with no FFL.

Bolts usually have the last three digits electropenciled on so they can be matched to the correct rifle in case they get mixed up.

Nope.

PTG, Clymer, JG can all make them. It won't be a regular part number though.
