Phoenix Weaponry’s 45-70 AR at 2018 SHOT Show


Phoenix Weaponry’s 45-70 AR at 2018 SHOT Show

As far back as I can remember, I have liked the 45-70 cartridge. It is a fine old round that fits my main preference points: Big, heavy, hard-hitting. So of course I love to shoot it in a Marlin lever gun, an old trap door 1873 Springfield, or a Ladies Home Companion. Or maybe even an AR?

Yeah, that’s right. Colorado custom gunmaker Phoenix Weaponry went to work and reinvented the 45-70 to operate on an AR platform. To make it work, they rebated the case rim (the rim was turned to a smaller diameter than the case body) to the size of a 308 case head. They say the resulting rounds can be “fired through a high pressure AR platform with shocking, sub MOA results, and a boosted performance curve.”

Sign me up!

Sadly, all I could do with the gun was fondle it, and the only personnel on hand was a kid repping for Hexmag who didn’t seem to know the definition of “centerfire.” But hey, fondling’s better than nothing.

Of course, this is a gun for reloaders — because 45-70 ammo with rebated cases doesn’t exactly grow on trees — and you can load them hot:

This case, once rebated, can be reloaded easily using existing load information for the 45-70, based on Ruger No.1 loads, and the reloader can use standard 45-70 die sets with the exception of using a 308 shell holder. Factory brass will be available shortly and available for purchase from Phoenix Weaponry. Each rifle initially will be supplied with 50 pieces of brass to help the new user get started.

The included brass is a nice touch; there’s nothing like ordering a rifle in a funky round and then having to break out the lathe to rebate a bunch of brass to fit. For the money, it seems only reasonable… though the #cheapskate part of me wonders why you don’t get a few hundred rounds of loaded ammo for the $4800 base price.

From company owner Aaron Cayce:

This is built on our RFL (308) upper/lower with a custom barrel and barrel bushing. This being said, we can build you one in any configuration, caliber, finish – we can do whatever you want, your budget permitting.

If you have a lathe to modify the brass, we can sell you the form cutter, or you can buy already-modified brass from us.
