Any thoughts on a 9mm blowback sks

I have been thinking about starting a winter project. I was thinking about rebarreling a sks to 9mm. And convert the bolt to blowback. Add weight to the bolt. Use an ar mag adapter and a glock mag adapter to run glock mags.

I don't know let me know what you guys think.
 
Might as well make it easy for yourself and keep your sks and for the 9mm start from scratch and cobble together a Sten : )

Just kidding of course because that would be illegal..

Sorry for not having anything useful to add, please keep us posted on your conversion journey

I don't think the SKS is a particularly good choice for this. The barrel is a b!tch to remove and then replace, the bolt face is the wrong size, you need to weld/attach the bolt to the carrier, probably need to add weight to that assembly and then rework the recoil spring to new parameters. Seems like a lot of work for a semi-auto PCC of very questionable reliability.

In the end, I think you would be better off buying a bunch of surplus ammo and enjoying your SKS in its original calibre instead. Of course, if you just want a challenge then go ahead and keep us all posted here.

I have a chinese sks with pressed barrel. So the barrel I think would be the easiest.

I was thinking weld the bolt assembly together.

The bolt assembly is fairly heavy. I need to weigh it again but I think it was about 12-14 ounces. So have to add like 10 ounces.

It's really just a project to mess with. Develop some skills. Have some fun. I built a 6.5 grendel sks about 6 years ago and enjoyed the whole process.

A sten bolt weighs 600g (21oz), which is a decent target for 9mm. It does have ~6" of travel, though, so you may want a bit more mass because the SKS bolt doesn't travel that far. You will most likely need a heavier recoil spring as well and a buffer at the back of the receiver wouldn't hurt.

In that case, have at it. And post a thread, I'm interested to see how that all goes.
