Gunsmithing Fluting an FN SPR/Pre-64 style bolt

Re: Fluting an FN SPR/Pre-64 style bolt

As I understand it, it is possible but very difficult as you have to create a track for the ejector to ride in that keeps it out of the flutes.

personaly i would'nt mess with it...you're taking one of the most absolutely reliable actions and making a maybe out of it, even if it is possible...my thoughts are the extractor <span style="text-decoration: underline">may</span> get hung up

just my $.02 and i am <span style="font-weight: bold">certainly </span>no g smith

Yeah, I was thinking that they probably don't do it because you would have to work around so many pieces if you wanted to flute it, but I would think that its possible.
 
Re: Fluting an FN SPR/Pre-64 style bolt

Possible, yes.

I would err towards the reliability though. I have a custom built on an FN & wouldn't personally mess with it. I chose the FN over the 700 for my build due to the inherent reliability of the controlled round feed design.

As it is designed, its an ultra-reliable action & needs no modifications to run.

My .02 cents on the matter.

Ya, probably not I guess.

Guess I'll try and find that.

I advise against it.

I have a Nesika with a mechanical eject. The bolt was mistakenly fluted during production. (I got it for stupid cheap as a result)

The flutes cause big issues with the mechanical ejector. It'll fall in and won't want to rotate out of battery. The only solution is to machine a trough for it to follow. Unfortunately you have a big ol ring that the extractor depends on.

Anything is possible and I was able to get mine to work well enough but I'd never buy/do one like this.

You have a good action. One of the best designs out there IMHO. Spend your money on bulletz n gas money.
