Sky-High Inland Repro Carbines

[INLAND44]

Painter; Olympic made a .30 carbine AR15 but eventually dropped it because of low sales. its such a natural caliber for an AR because the same 5.56 bolt would be used. Then you need a .308 barrel with a 5.56 barrel extension and a chamber insert for .30 Carbine. The hardest part but not out of the question for a good tinkerer is building an M1 Carbine magazine into an AR mag body. Once you got it basically running, you probably would have to lighten the action spring and buffer.

Yes, the traffic is awful in 'Nawthun Vuhjinyuh' so I try not to go up there unless it can't be avoided. I might ride up, catch the Metro at Springfield and ride over to see a Redskins game every so often when I feel the need to 'wear the hair shirt'. Then there's a huge gun show in Chantilly a few times a year that's worth going to - its even more fun to go to it because it's in the shadow of 'The Beast' (DC), one of the most gun-hatin' holes in the world.

I'm not sure I see what the advantage of an AR15 platform chambered in .30 carbine would be over a well maintained M1 carbine. Starting in the late '90's I carried a M1 carbine in my patrol car as a deputy sheriff for about 10 years. I had to qualify with it a couple of times a year standing next to other officers shooting black guns and the only real handicap to the M1 carbine was the cost of .30 carbine ammo compared to .223.

To me the value of having an AR in .30 Carbine would be in several areas, mainly not putting wear on my G.I. carbine. Other benefits would be manifold, such as having a modern platform for optics (rails) that would also be easily customized, readily available parts and the transfer of familiarity from one's other ARs. As I said at the beginning, I no longer have any practical use for the M1 Carbine. When I got it over 20 years ago, my thinking was different than today. I now consider the carbine a collectable that will not be fired except very rarely.

I would try the standard mag, maybe a filler at the front to keep them back and just open the gas port until it runs...I should think...

I wondering about this muzzle flash in handguns from the carbine round. I'm thinking similar length cartridges in handguns - 32 H&R, 357 etc magnums etc in similar handguns, but nobody comments about muzzle flash in them. Please enlighten me, I would dearly like to know.

Hi Daan,

Please enlighten me, I would dearly like to know.

The .30 Carbine round is a rifle cartridge and operates at higher pressures than the handgun rounds you mentioned. The pressure specs are nearly double that of the 32 H&R and roughly 15% higher than the 357 magnum. Out of the shorter barrel (rather than the full 18" Carbine barrel) a lot of the energy is wasted as the bullet exits the muzzle, and results in the flash. At least, that's what I believe causes it. - Bob

The powder used for .30 carbine ammo is tailored to an 18 barrel so firing it in a short barrel of a pistol means a lot of noise and lots of flash. The powder keeps burning after the bullets exits the barrel and one has a large fireball.

As cool as it looks. It kills my follow up shots.I shoot mine once in a while, just for kicks.

I wondering about this muzzle flash in handguns from the carbine round.

They made trial pattern 1917 revolvers and Ruger for one made the Blackhawk in .30 carbine. The report was like an anti tank gun firing and the concussion was reported to clear both the shooter's bench and the firing line... It was unpleasant to say the least. The 1917 trial revolver was not adopted...
