I've been wanting a short barreled bolt action rifle in 9 mm for a while.

I happen to have an already papered Mossberg MVP in 5.56 with an 11" barrel that uses standard AR15 magazines. My thoughts are that I can simply put in a mag block adapter and as long as I have a barrel made for it in 9mm I will be golden. It'll be that easy! I ordered a mag block and some magazines to see if they'll work with my action/stock combo. They'll be here next week.

Have any of you attempted such a thing?
Does anyone have a gunsmith recommendation that may be willing to take on the project?
If not, recommendations for someone to custom chamber a 9 mm barrel blank for me?

Watching...…. I've thought about a bolt gun if 45acp or 9mm. I think I have some type of fantasy to recreate a De Lisle Carbine...… I always thought that was the coolest gun.
 
A guy on ARF just posted the same thing. How have I not seen that until now?!? That’ll be a much better option than the mag block.

CHRIS
Don’t worry...you’re only a couple weeks behind me. Somebody else posted about them here somewhere recently. :D
 
Sounds like a neat idea.
@Slacker built a cool .38/357 bolt gun.
Maybe he’ll have an idea or two.
 
It would be really cool if you could use a super short action, like a 22lr.
Sucks that the bolt throw will be long enough to eject a 5.56 round with the tiny 9mm.
A straight pull / Olympic style action would be killer.

How about that RIA 22TCM bolt action?
Isn't it setup to swap to 9mm?

ETA, just checked, it's only the pistol that swaps calibers.

Could you use these instead of a mag block? Might be a good application for it.

Well that’s just cool.

Only downside seems it’d be tough to clear the chamber with a partially empty mag.



To stay on topic. A 9mm bolt carbine would be awesome. A fellow local around here has a Spanish surplus that shot 9mm largo. It was a cool little setup. But those rifles (I forget the name) are rare and finding ammo would be tough.

Looking forward to this project.

I tried the short case ejecting test and failed miserable. Like mentioned above, the long distance from the chamber to the port lets the brass spin off of the front of the bolt to fast and it drops.

@BatteryOaksBilly Is this something that Brian at SSK would look at? I think we could make it work if the right lug of the bolt is trimmed some and a filler of sorts is put into that right lug's channel on the actual receiver. Something to keep the brass from falling off the front of the bolt.

I've got to look at those TCM rifles. That SAI conversion was what got me interested in this project. I was hoping to be able to use my already purchased rifle and stamp though!. lol

Know someone who rebsrreled one of those into 9mm worked fine. And used the rockisland doublestack 9mm mags. He didn't buy the kit though just found a barrel blank and had a gunsmith dpmthe rest

Quick update. After several messages with a couple of different knowledgeable folk the consensus is that the MVP as a donor action may be possible but it would come at a big cost. So the MVP is off the list for this project.

I'm now officially on the lookout for one of the RIA TCM rifles for a donor. If you have any leads let me know! I've got my auto-bid set up on Gunbroker already. :D

$389 here: https://tooeleshootingsupply.com/sh...75-inch-bbl-wood-stock-5-round-armscor-51108/

Two in stock, $9.95 shipping

PSA shows them in stock for $399.99, plus you pay tax and about 2x the shipping cost.
 
@BigWaylon I snagged one a couple of minutes ago.:) Also have an auto-bid set up on GunBroker for a used one. I may end up with two of them.

@JBoyette That's the way I was heading. Lighter profile will be nice. I'll probably F1 a dedicated can for it.

OAL cut it to be suppresor + 16" then rockset the direct thread can body. Buy a can that allows the front cap to come off and remove the baffles. This conversation removes the SBR tax stamp ;)

Not exactly sure if what you typed is what you meant...

But a <16” barrel with a suppressor attached with rocksett is still an SBR.

Nope, if its over 1100degs to remove it the ATF considers it a permanent attachment based on Silver Solder ruling. FYI

"The ATF procedure for measuring barrel length is to measure from the closed bolt (or breech-face) to the furthermost end of the barrel or permanently attached muzzle device. Permanent methods of attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100°F) silver soldering, or blind pinning with the pin head welded over. Barrels are measured by inserting a dowel rod into the barrel until the rod stops against the bolt or breech-face. The rod is then marked at the furthermost end of the barrel or permanently attached muzzle device, withdrawn from the barrel, and measured."

Rockset:

"High Temperature Rocksett. The All-Purpose Engineering Adhesive Ceramic Cement ...One Grade Does it All! Locks, Seals & Bonds - Nuts, Screws, Shafts, Keys, Splines, Pipes, Flanges, etc. incredible Temperature Resistance (-350°F) up to 2,015°F. Electrical insulation for both A.C. and D.C. up to 20 Radio MHz. Non-Toxic- odorless - non-flammable. Rocksett withstands oil, fuels, acids, alkalis."

Rocksett isn’t silver solder, or welding, or blind-pinning. Pops loose with nothing but torque, or a soak in water.

I’ve never seen anything say it counts as a permanent attachment method...but I’m not sure I’ve ever read the “silver solder ruling”. Share it if you have it handy.

Colt, LMT, Knights, send an email to NFA branch and ask. We did it a War Sport and it was approved as a 07
 
Side note, to perm weld a pin, its easier then rockset to be honest. If you went that route too, its a 10 min job. Just get a thread on can, thread it on, mark the location, remove the can, drill a hole large enough to use a AR15 barrel index pin. Once you screw back on the suppressor, drill a hole in the barrel threading enough to set the pen deeper than the threading of the barrel and insert the pin, weld the hole closed and BAMB done!

38 spl / 357mag, but same idea.
2 stamper.
I have since added a 3 lug adapter.
It's not conductive to accuracy but is handy as heck.

ETA, I built this gun to use 220gr .358 speer deep curl JSP bullets in 38spl brass and it works extremely well. I copy 300blk subsonic load data.
It’s a lazy mans 300blk since no finicky headspace to worry about. Love a straight wall cartridge.
I can load ammo with a Lee hand press if needed.
It works really well with 158gr 357 mags also. I can achieve 30-30 energy at 100yds with no problems.

Nice job on the inlet! I couldn’t remember if yours was an integral or not.

My parts showed up. :eek: The rifle that wasn't meant to be! lol

The first rifle showed up today. This is a new one. Came in a sealed bag soaking in some sort of oil. I spent a while wiping it down and was finally able to look it over.

Trigger is a little gritty but has a built in adjustment for take-up. If it could be smoothed out I think it'll be a fine trigger. I popped it apart and these are the major components. Barreled action, full on mag well/trigger housing, a couple of small screws to attach trigger housing to action, a couple of screws to attach stock, and a 1911-type mag release.

I did notice that the mag well/trigger housing was about the same width as a 10/22 action. Hmmm? It would only take a little metal removal for it to drop into this PMACA 10/22 chassis.

I'm submitting my E-Form tomorrow. In the meantime, do we have a Carolina gunsmith that anyone knows who would take on the 9mm conversion? And hopefully, wouldn't mind spending some machine time and trying to shoehorn that re-barreled action into that chassis? I don't mind sending it out for the conversion now and having is chopped/threaded later on.

CHRIS
 
I wanted to point out that I'm primarily looking for a gunsmith that will do the caliber conversion for me. The silly chassis thing can happen at a later date. I don't mind using the wood stock for a bit.
Feel free to make recommendations...even if it is yourself! :)

Is that stock maple?
The comb drop looks extreme for a rifle with no iron sights. Almost shotgun-ish.
Maybe it's just my eyes.

Did you already run it by Brian/Michael?

Not sure. It is wood but has a "fake" finish. All coloring is supposedly from the stain used and the black tip on the front is sprayed on. lol. You can see the over spray on it. Ha!

CHRIS
 
Quick update. I found a couple of guys that will help with the conversion. One is doing up a regular setup like came factory. The other is working on converting to something similar to the Savage barrel nut setup. I e-filed two Form 1s yesterday. One for a diy silencer and the other to SBR this rifle.

The second rifle will be delivered on Tuesday. I'm waiting on my barrel blanks to show up and then will send those out for work.
