Where can I find them, the only places I've found them they are 12" long or 1 in 52" rifling, or ~$125...

Anyone know of a lower price?
Thanks!

AFAIK 45 acp blanks have been in short supply for about 2 years. They guys building AR-45s have had a hard time. I suspect it is one reason Olympic has been trickling out 45 uppers for so long.
Have you tried ER Shaw? I wanted to try to buy a bunch of blanks from them but keep getting other projects ahead of them....

Thanks, though it looks like it'd be $155, I'll just have to keep my eyes out, maybe use one of them carbine conversion barrels for a M-1911, if I can find one cheap, just use it like a .22 barrel liner...

Green Mountain has 25" barrels in 45 Colt (shouldn't be too hard to convert) for $85.

They also have 15" barrel blanks in 45 caliber for $79 - add a permanent muzzle device to get 16".

Have you tried Numrich gun parts?? I got mine there for my 45 auto and butt stock also.

The .45LC uses much slower twist rifling, about 1-32" rather than 1-16" for .45ACP, I wanted to build a "suppressed without suppressor" rifle, to sound something like a .22lr, probably a 20" [though I'd go to 16" if it was all that was available...] barreled .45ACP mauser

Ok sounds like a good Idea I wish I knew how to make a suppersor Id be happy.

The thing is, it isn't a suppressed rifle then, it just has a long enough barrel to let the pressure dissipate a bit before the bullet reaches the muzzle, therefore there isn't any legal issues...

I found a local source, $87 for a 20" .45ACP barrel liner, thanks for the suggestions though!

At one time Reineland sold a .45 FAL conv kit.

They may have a barrel you can use.

There was some other site that had the whole barrel assembly for like $150 or so, though I could just get the barrel liner I've been thinking about, drill out a worn out / rusted to crap barrel, and solder the liner in that, now I'm off to look for cheap mauser barrels...

Well, now I can't find any, anyone know of a place to buy a mauser barrel with a bad bore?

Are you looking for a german 98 type Barrel?? I might have one I will have to look to make sure.
Joe

Have you considered contacting KAHR Firearms, they make the Thompson clones
and most of those a 16 inch barrel.

Thanks for looking, I'll only end up using the threaded part, so I may well just figure out how to use the lathe for threading and make my own outer barrel [to house the sleeve] it has a quick change gearbox for threading, I've been looking for a project to use the lathe...

So are you saying, you think the report of a 16" barrel 45acp will be significantly quieter than a shorter barrel?

My Rhineland mauser .45acp conversion sounds about like a .22. It clover leafs at 50 yds. too! If your just looking for a quiet pistol caliber rifle, why not get a Marlin .44 mag or .45 colt and custom craft some quiet loads for it ( heavy bullets, fast powder)?

I can't afford a new rifle, besides, a little lathe work is fun, besides, then I'd have to get new dies and brass for the new caliber...

I've been thinking about doing a "whisper" type cartridge with the .45 and M1 carbine mags, just seat the bottom 1/4" of a really heavy [300 grain cast] bullet in the case, though that probably won't happen, or at least not for a while...

I have a 16" AR45, and it seems to be just as loud as everything else we were shooting that day.

Next time I will try to pay more attention to the report. Perhaps a bolt action IS a bit quieter.

:bow:

I wish I could afford one, mostly the upper, I could get a normal lower forging, and machine it different [maybe weld a bit of metal onto the sides of the magwell] to take M3 mags...

smoe guys are buying the cheap antique barreled actions from centerfire ('71 mauser) for the .452 slow twist barrels, which are reportedly salvageable.

Well, I'm going to go to the place this weekend to get the liner, I may make a semi auto, with a AR-15 FCG, though then I gotta find mags, anyone know of a place to get M3 mags cheap?

How are you going to get a grease-gun mag into an AR magazine well? (too wide)

I put a My Rhineland mauser .45acp conversion on a turk mauser and it works well, and I pick up wolf steel "brass" and load them to magnum levels and it has some kick.
the normal loads are still abit loud.

But if you use a load with a fast powder it would really not make much noise with the long barrel, this is just a swag, is there anybody who with loads like this?

I use Unique, and it seems as loud as in my pistol.

New G3(M3) mags are about $20, Old or used should be cheaper. I think Shooter Solutions is making new mags. They have had group-buys for $15.

You need a different receiver to fit a GG mag in an AR platform. This is why the AR45, Bazooka Bros, etc make new lowers to accept GG mags.

I expect you meant "M-3" magazines.

G3 mags would be quite a bit harder to fit into any type of AR-15 mag well.

I'm going to go with sort of a stamped AK type construction, except recoil operation, and constructed with square tubing, and the bolt riding on the edges of the tubing, with the side with the seam cut off, like an MG-47 [a belt fed AK, made with RPD feed parts] and then use a AR FCG because there are a couple just sitting here, or maybe the non usa made AK FCGs that are sitting around, I don't know yet... I might just get a 16" 1911 barrel from sarco, it'll save the chambering step, and it already has a feed ramp, I'd just need to make a feed ramp to feed the double column feed from the M-3 mag into the chamber...

I have built a couple .452" groove barrel rifles.

I have used Shilen Chrome moly barrels.
These are not lapped unless custom ordered.
Don't use these if you can get Green Mountain.
GM un lapped barrels are better than Shilen unlapped barrels.

M-3 mags are single position feed. Thompson SMG mags are double position feed.

Okay, I got the liner, I got it from "The Track of the Wolf" they deal with muzzle loading stuff. It would seem that someone in Kentucky makes them, from the shipping label...

I'm starting to believe that it'll probably be pretty loud, but nonetheless cheap to feed with cast bullets. Maybe a sort of noveske flash hider thing, to direct the noise downrange will go on it [thinking way ahead here].
