If I were going to do something like this, I would probably go with a 12-inch barrel. The end result would still be really compact without sacrificing much muzzle velocity.

Speaking of muzzle velocity, isn’t that a significant appeal of .400 Legend–impressive muzzle velocity from a compact cartridge with heavy bullets?

On the topic of .400 Legend I purchased a new bolt-action rifle chambered in .400 Legend in October. I managed to mount a new scope and sight it in by middle November. I am pleased to report that it delivered a bullet on target to a nice 2.5 year-old white-tailed deer buck a few days after sighting it in. I am looking forward to more days afield in December to add more meat to my freezer.

If subs won’t cycle the action, put a can on it
That’s what subs are made for anyway

Yup. Get a .458 SOCOM upper, BCG, and mags (standard AR mags require a slight modification for optimal performance, especially with extra-heavy subsonic bullets) from Tromix. Its owner (Tony Rumore) created the original .458 SOCOM prototype and is the acknowledged expert on it, and their prices are reasonable.

Get your ammo (optimized for whatever application you want) from Southern Ballistic Research. They are similarly regarded as the experts on .458 SOCOM ammo.

You’ll be GtG with an extremely heavy hammer for hogs and most big game (inside 100 yards), and of course for self defense against two-legged predators.

In reply to LKB. I thought that same thing, heavy-hitting big bore AR then go with .458 SOCOM.

If you want a heavy-hitting, big bore AR, why not just go with the caliber specifically designed and optimized for that: .458 SOCOM?

“When I Form 1’d it, I put in the reason block “Personal defense against robots, cyborgs, rhinos, and genetically re-created dinosaurs and all other lawful purposes.””

I did a form 1 for a ‘heavily customized’ build a while back during the Biden tyranny – I used a 14.5 inch barrel and I was not going to do that stupid pin/weld thing with a flash hider just to make it 16 inch. For the reason block I put “ATF, and actual lawful purposes.”.

I still have several Faxon 14.5 inch barrels, and after Jan 1 2026 I’m gonna use them.
