I got a new old IDF synthetic stock for the M305. Fits perfectly at the receiver but there is a 1/4 inch gap at the front ferrule. Is this ok or should it be shimmed?

Also while I am working on the rifle, I tried the GI bold I had ordered back when my MIM bolt blew up in my face. Fits and functions perfectly. Should I check anything else before firing the rifle?

Thanks for any input!
 
Yes, you need to have the bolt gauged with headspace gauges. If you don't have the gauges and knowledge, it's a gunsmith task.

What part of the stock has a 1/4" ferrule gap? Are you talking about the tip of the stock is 1/4" from the stock band at the back of the gas cylinder? Can you take a photos so we can see what you are referring to?

As others have pointed out, that gap is supposed to be there - and that's WAY FAR from being 1/4". Looks more like 1/32 to 1/16" max.

On norinco stocks, the ferrule often touches the band - a bad thing that begs for fixing.

With that gap, all you want to check is that the barrel port is aligned to the corresponding hole in the gas cylinder.

A tip: pull off the gas cylinder and find a drill bit that fits in the gas port snugly without binding. Re-assemble the gas cylinder, but leave the piston out. Put the drill bit in through the bottom of the gas cylinder and make sure it sill goes into the barrel so you can see it down the bore. If it does, then you aren't cutting off gas flow and your cylinder is properly timed.
 
Nice! Glad I can leave it as is, the cheek riser on this stock is exactly the right height for the scope.

Greasing the front ferrule is weird but I guess it won't hurt.

Is bedding the action important in those stocks?

It depends on fit of your action. SEI uses GI synthetic stocks and they routinely get 1.5moa without bedding.

I would shoot the rifle and then decide if it needs bedding.

Not to sound stupid.. but the reason for bedding is what? Only thing I can think is it keeps the action firmly in 1 spot in the stock.. is there any other reason?

Yes, that's the basic principle. Bedding gives you action positional consistency from shot to shot, moreso than the basic stocks, which can cause hte action to shift a few thou between trigger pulls.

Bedding is also used on NM rifles to improve the draw pressure and trigger bow pressure when done correctly.
