[NEW stock adapter for use with 20rd drums!]

The next question is how durable is it? Will it handle a butt strike?Does it lock tilted with another button that needs to be pushed, or does it just twist around on its own?

 

It is very durable. It has been tested on a full auto shotgun for thousands of rounds. As with a stand alone folding mechanism the butt stock screws are the weakest link, they will shear before anything else fails. When folded and rotated around a drum, you only need to twist butt stock while unfolding to return it back to shoulder fire position. The button only needs to be pressed once while folding the stock around a drum

whats the new combined thickness of a folding mech and this swinger? looks like your LOP is gonna increase by a inch or so.

 

The adapter itself is just over 5/8" in thickness

can it be used with a pig nose adapter for collapsable stocks?

 

Yes I designed it to accept a pig nose adapter so collapsible stocks could be used

Mike Davidson (MD Arms) showed me his prototype for this almost a year ago, at the last Pumpkin shoot in Lapeer, MI. Not sure if this one is his or not, but it looks like a neat idea for folks that run drums.

 

Actually the prototype that Mike has on the gun is my product. I work for Mike and I have had that prototype on our full auto shotgun for a while. I figured one of the best ways to do a durability test would be thousands of rounds of hard rugged use in a full auto.
