Nesieka RBLP Magnum to Standard Conversion

[ricco1949]

I have a RBLP Nesika K with a magnum bolt.

I would like to convert the bolt to standard .308.

Can I simply ring the bolt head or do I also need a different standard extractor?

You might check with Chad at Long Rifles Inc. He use to work with Nesika actions.

Yes, I'll probably call Chad next week. I don't know if a longer sliding plate extractor is available if necessary.

Did similar years ago to a J with a cone bolt. Bought two bolts and opened one to a mag face. Ended up plugging the extractor plunger hole and relocating it to work with the mag diameter.

Is it coned or flat face? Flat face extractors aren't that hard to make.

It's a coned bolt. I may try making one before going Alan's route above.

Clamping for the angled extractor cut looks like a challenge for a self taught wanna-be though.

Thanks for the advice.

What did you use to plug the original plunger hole? Epoxy or solder?

Thanks for the advice.

I have a bunch of extractors. Most I don't know what they fit. Get me a couple of measurements.
Width of the slot, upper and lower.
Thickness of the T section that slides under the slot.
That will narrow it down quickly.

Thanks Dave. I'll send a drawing this AM.

Some guy just leave the original ejector in place and add the second one.

Thanks for looking Dave.

Rather than cut up a good action, I would take the opportunity to build a new rifle.

Not cutting action or bolt. Simply soldering in a ring in bolt nose that could be removed later to reconvert to magnum.

Be nice if I could find a .308 bolt only for a Model K.

Nice job on the drawing.

Nice job on the drawing.

Thanks...10th grade engineering drawing was a distant 60 years ago....I'm a little rusty.

Sorry all of mine are larger.
This is how I've made some in the past. You'll make them two at a time.
Round stock- turn the OD and ID to the diameters you need.
Setup vertically in a mill and make the four cuts needed to get the inverted T.
I then cut them off with a jewelers saw leaving the wide T section long. Easy to mill this to the correct number.
Then worry in the claw part. Rotate the mill head or use an adjustable square to get the angle close for the lip.
Drill hole for the retaining pin.
Grind chamfer on the lip to allow the case to push the extractor back.
easy peezy
Then get part #2 and repeat knowing much more you now know than when you first started.

Dave, thanks for the how to...I'll give 'er a go.

Humorous last line...

Gonna call Chad first to see if one's available somewhere.
