A M-14 in 5.56 NATO would likely be a very tame beastie. Some photostudies of it functioning would be interesting.

 

After they do that, they should of shortened the rifle, maybe replaced the materials it was made with, and give it a 30 round box magazine and some cheese graters to mount things

You mean "Make a proper Mini 14"?

The US Army Small Arms Systems Agency (USASASA) introduced the Dual Cycle Rifle (DCR) concept back in 1971. The brainchild of USASASA commander Colonel Raymond S. Isenson and Technical Director Leonard R. Ambrosini, the "dual cycle" referenced a burst being fired at a very high rate while feed and extraction occurred at a fraction of that speed. Testing of the SPIW had already shown how a conventional high cyclic rate mechanism with a single chamber and barrel could be unreliable. The SALVO-era multiple barrel designs suffered from excessive weight and bulk.

 

Fifteen companies eventually submitted proposals, and four of these were accepted for further study as paper designs. Two companies, General American Transportation Corporation (GATX) and General Electric (GE), were ultimately selected to develop firing prototypes. The winning proposals used a single barrel combined with a multiple chamber cylinder. The cylinder was fed from a box magazine holding three individual rows of cartridges. During the feed cycle, the top three rounds were simultaneously stripped into individual chambers. GE's design used an asymmetrical three-chamber cylinder while GATX's design used a symmetrical nine-chamber cylinder. By 1973, the prototypes reportedly achieved cyclic rates of ~4,500 rounds per minute in three-round bursts.

 

The US Army's basic design was US Patent #4,102,241:

General Electric was US Patent #3,788,191:

I have not been able to find a DCR patent directly credited to GATX.

 

There is a small article on the DCR in the May-June 1973 issue of Army Research & Development Magazine:

People who wander around in Alaska, mostly.

 

I remember it being particularly popular with these types or just other places where dangerous or large, territorial game are common.

 

One bonus of it is that it's rather tame in recoil compared to other rounds used for things like charging bears like the .454 Casual wrist murderer 2000.

Also, who actually came up with the abbreviation "USASASA" and thought it was a good idea?

 

I would refuse to say that out of principle of I was involved with them somehow because that's just downright tomfoolery.
