Nice job!
I'm not sure why you did this but 'just because' is often an acceptable answer. Any other projects on your radar? |
I can explain it to you but I can't understand it for you.

Got any chronograph data? I'd love to see the velocity from the longer barrel.

Very impressive sir. This catches my attention because I have hunted with a Ruger Semi in 44 Mag. Always wanted an AR pattern gun to use instead because the Ruger was worth too much to take out. My compliments.

Bolt looks like some kid in china machined it / honked it out with rocks.
I bet it does not last very long before shitting the bed and lugs start breaking off. |
|

If the bolt does break, OP will be able to do a Mark 2 version.
That's hella cool. |

The strength of the 5.56 bolt lock up is of course the consideration that the entire concept revolves around. Just to give 2 sample posts that give you a little of what can be the truth in such a nebulous question, read these through.

I dont think I'd put my face behind this guys conversion but he has. I don't know if he's still around. Start reading at #36 for it in the AR. https://www.pirate4x4.com/threads/build-thread-for-the-510-reedwacker-per-request.1116600/page-2?nested_view=1&sortby=oldest#replies |

Holy crap, that's amazing. Nice work!
Is this the first .44mag AR? I'm not sure I've ever heard one, ever. |

Prohibition doesn't work.

There are several 410 BCG’s that are commercially available. The rim diameter of the 44 magnum is 0.02 inches smaller than the 410. I’m pretty sure that bolt (410) would work.

Also aren't most of the .410 uppers piston operated with tabs on both sides of the BC face that are pushed by the coaxial piston? I guess you could remove those tabs. As for the OP's AR44 mag, I think it's pretty cool and creative. |

I'd call Bear Creek Arsenal to start; I've purchased odd sized bolts from them before. They can probably direct you to who makes them.
I have used 444 Marlin brass for 410 ammo in my AR; the rim size is identical to the 44 mag. |

Bravo Zulu, OP. |

If a .410 bolt can be used, I wonder if perhaps a dual caliber AR could be built that could shoot both .44 mag and .410? A project like that might be interesting, especially if it were an AR pistol, which could perhaps skirt the SBS restrictions of the NFA by actually being a pistol caliber that just happens to be able to shoot .410 shotshells as well. Those pistols that shoot .45 colt and .410 seem to be popular. Surely, an AR that could switched between the 2 with just a mag swap and maybe a turn of a thumbscrew on a gas block would be popular as well?

Going a different route , is there any reason a rimless case like the 44 or 357 automag wouldn't play well with the DE mag?
Could use a socom/bushmaster bolt . - maybe a rebated rim 429DE on socom brass ... - 9mm mag on 350 legend brass ... |

Thats awesome

They used standard AR-15 magazines with a ramped spacer block in front with a short stainless steel sheet metal follower. The basic magazine design concept was copied from Mario Palambo's (American Firearms, Commerce City, CO) 50AE magazines, circa 1994....albeit with quite a few manufacturing changes.

I thought there might be a cartridge angle contribution of the rim . * I had a 44DE and a ruger Deerfield back in the early oughts ... it always crossed my mind to go 440-429DE . |

Good post. This is a seriously cool project.
I like to read about the unconventional things - a rimmed large diameter cartridge certainly is one of them. How is your magazine functioning? Did it take you long to find a good magazine to do this conversion? |
