Is the .308 upper for 5.56 lower out yet?

[DrDoot]

Saw a thing at the shotshow about a company making .308 uppers for regular 5.56 lowers, wondering if it is out yet?

My mind boggles atm on how you could fit a .308 into a .223 magwell. Last I checked, a .308 was too long to do so.

I could very easily be wrong though.

I suspect that it is doable if you want a single shot ar that won't last very long.

MGI Hydra? Not quite a regular 5.56 lower though.

Then there was CMMG making G3 mag lowers for use with DPMS and AR-10 uppers. Though again, not a standard 5.56 lower.

First i heard of that combination. I cant see how its possable, unless you use some type of mag block in a .308 lower.

7.62 NATO's case is 51mm long, the 5.56 NATO case is 45mm long.

Square peg in round hole.....

Is this the AR15 platform with a 308 bolt face? I thought it was the 30 Remington

I'll add this weapon to my Unicorn/ACR list.

It was a special on the Outdoor Channel covering this year's Shot Show. The company wasn't one I had heard of before, and yes the .308 bolt face sounds familiar. It was a standard 5.56 lower, no idea if it was a single shot rifle or what the gimmick was.

I don't think it was this rifle but I've also seen an upper (either out or in development) that feeds from the top or side with a magazine and ejects shells out of the traditional magwell.

Must be this:
