The easiest conversion of the lot.. All you need is the barrel. Fun to shoot as well..

and probably a few dozen more calibers. Many more calibers that require a different bolt as well.
There are Blow Back, DI, 5.56/.223 ar bolt calibers, custom bolt sizes, and a slew of different things. Many wildcat calibers for the AR, many botique uppers and calibers as well. IMO there is so much out there, and so many people making custom parts, barrels etc, that you can find almost anything. Only issue is, ammo rarity. Most of this stuff requires reloading etc as you typically won't find most of these calibers in your local gun shop.

Post #1 from the guy bumps an ancient thread to suggest Beowolf?

You guys get cranky when we start new threads.......

[Iraqgunz]

Starting a new thread is one thing. Reviving a thread that was almost 6 years old, in which there is almost no interest or response is something else.

I think it's a very interesting question. I would be very interested to know which of these calibers would use the same bolt face as the 5.56 and which would require a different or modified bolt. But maybe I should start a new thread on that. ;)

This page has most of the calibers, including a breakdown of which use normal ar bolt, which take custom bolts, which are blow back etc.

I do now, whoops

I thought the thread was interesting, didn't even realize it was from 6 years ago, haven't been here that long and probably wouldn't of happened upon it.

I run and frequent many forums, there is always a personality to all of them.

Just have one question iraqgunz, why are you so bothered by this being resurrected? I don't see the issue with the OP date, the thread overall is informative and intriguing.

It's been reopened so who cares. Contribute to the thread or it will die again.

I'm thinking of doing a Beowolf build now. ;)

Are you going to put that on your LWRC lower? Do they make SMK's in Beowolf?
