This came up in an earlier thread, but I think it's just too cool not to start a new one. This is Robert Hillberg's design for an ultrasimple insurgency (or counter-insurgency) weapon, initially a top-break four-barrelled shotgun not unlike a scaled-up version of the old Sharp's four-barrelled pepperbox.

Hillberg's patent and drawings at Google Patents (http://www.google.com/patents?id=peJpAAAAEBAJ&dq=3260009)
"Hillberg Insurgency Weapons" at Guntech.com (http://tml.travellercentral.com/hillberg/index.html)

I especially like the simplicity of the original design, and I think it would adapt well to modern materials (stainless barrels, latch and mechanism, all the rest in polymer) with lower cost and lower weight. The original four-barrel magnesium, steel and wood Winchester Liberator prototype in 16 gauge came in at 7.6 lbs. The eight-barrel aluminum, steel and wood Colt Defender in 20 gauge weighed only a pound more.

I can definitely see an 18" barrel one with a fixed stock for general purpose use or a short-barrelled dual-pistol grip model for serious close quarters work. A folding-stock .410 gauge model could come in around 5 lbs for a great home defense gun for the elderly, the recoil shy, or anyone looking for something simple, handy and light.

Thoughts, anyone?

Hillberg's next design, the Colt Defender, looked even more freaky (but would still be an interesting shotgun to recreate today); the Defender was designed as sort of an all-purpose anti-riot gun, and had 8 barrels surrounding a central tank for aerosol tear-gas (the trigger on a forward grip fired the tear-gas, while the rear trigger cycled the hammer through the barrel cage, the same way the Liberator did). There's no reason someone couldn't do the same thing today, only with a selectable hammer position for an inner and outer cage 20 gauge or .410 on the outside, with an inner cage of 22 LR, or a single central barrel for 12 gauge (possible liability issue, with a 12/20 mix-up) or a centrefire rifle chambering.

Thanks, the Colt Defender is also featured in the article link I provided in the initial post.

That dual purpose version of the Colt Defender does make me a bit nervous, though, as I would be afraid of pulling the wrong trigger under stress. Better to separate lethal from less-lethal in entirely different weapons, IMHO. I do think the move from four to eight barrels in the Colt version tends to defeat the purpose a bit as the increased size, weight and cost starts to erode any advantage over a pump.

On a related note, I would like to see someone come out with an inexpensive combination rifle-shotgun like a refined Springfield M6 Scout or a cheaper Savage Model 24. For a truck gun, camp gun, boat gun, etc. it's great to have a whole range of choices from (.22LR to 12 gauge depending on the model) in one handy weapon.

Thanks for the info here. I see little need for the Liberator in any variation, but it's a fun thing.
