Default Geek's Calico M-100S - About & Disassembly

I thought I'd post my most unique rifle so far. It's a Calico M-100S. Last summer (July 2008), I fully disassembled and fully cleaned it for the first time. I'm pretty sure it had never been fully disassembled before. It was a pain in the ass. I think doing a yearly disassembly/cleaning will make things easier in the future. This model was produced from 1986-1994



Type Rifle/Carbine
Place of origin United States
Manufacturer Calico Light Weapons Systems

Specifications
Weight 3.7 lb unloaded
Barrel length 16 inches
Cartridge .22 LR
Caliber .22
Action Blowback
Rate of fire Semi-automatic
Muzzle velocity 1400 ft/s
Effective range 100 yards
Feed system 100 round magazine

Disassembly

Disassembling this firearm is not very complicated.

Step 1). At the end of the barrel you'll see the front sight and compensator. On the top part of the rifle, between the sight and wooden foregrip there is a pin. Use a punch to get it out. once that's out that front piece will slide off.

Step 2). There is a screw holding the grip/stock onto the lower receiver. Unscrew that and it'll come off.

Step 3). This part gave me a ton of trouble. The wooden stock slides off. Mine was stuck on really tight. I used a lot of penetrating oil and after about three days of working on it and letting it soak, it came off. When removing it, pull straight forward. Don't twist the fore grip. It's around a nut and twisting the grip could damage it.

Step 4). Remove the two push pins.

Step 5). open it up, remove the components, and you're all set.

Step 6). Clean and oil like normal.


From Wikipedia:

The M100 is a blowback-operated semi-automatic rifle chambered in .22 LR or 9x19mm Parabellum, manufactured by Calico Light Weapons Systems in Hillsboro, Oregon, USA and possessing a unique 100-round helical-fed magazine mounted on top of the weapon. The introduction of the Federal assault weapons ban of 1994 made manufacture of the Calico family of weapons for sale to civilians illegal due to the high magazine capacity, but now that that legislation has expired the company is free to build the exotic firearms in their original configuration.

From the Calico website:
About Calico

Beginning in October of 1982, California Instrument Company designed and built specialized instrumentation for the petroleum industry. Armed with a background in tooling and engineering, a totally new concept in firearms magazine technology was developed and in May of 1985, the first working 100 round helical feed .22LR carbine prototype was successfully tested. Eventually, an entire family of firearms was developed around this revolutionary new design. By June of 1989, the first 50 and 100 round 9mm “double helix” firearms were being produced. These robust weapon systems were hailed internationally as the next generation in firearms development. Enjoying worldwide success, Calico Light Weapon Systems now features a full line of calico accessories, like the world’s only true speed-loader, making it easy to capture the full advantage of this unique design. Always looking to the future, Calico engineers are currently developing new weapons and munition feeding systems that take advantage of our internationally patented design configurations. At Calico, we are committed to our “revolution in firepower”.

Helical Feed Magazine

The heart of the Calico’s weapon systems is the patented helical feed design. Using a staggered helix principal, the rounds are driven forward along a fluted cartridge carrier as they press against the helical wells of the magazine cover. The driving pressure is achieved by a rectangular torsion spring located inside the fluted cartridge carrier. Moving forward one by one, they are fed by a specially-designed feed port into the top-loading chamber of the Calico firearm. Calico’s helical magazine feeding systems remain the most advanced method known for efficiently storing and dispensing ammunition in small arms.

Oh man... that gun has always been cool. I remember back when it was in the Punisher War Journal when I was a kid.

Incidentally, that's an actual pic of Jake in his prime, circa 1885.

KOOOL rifle there Matt, didn't they make a 9mm version also? That ought to be worth some $$$$$ the way it looks. Will you be able to sing "Oh Canada" and hold that at the same time????

That's not mine specifically. The one I have has slightly different wood. Nope, they're banned in Canada by name. High cap mags are a no no - 10+1 rounds for pistol and 5+1 for rifles. AR15's can have the pistol mags.

Moving firearms back and forth from US/Can will be challenging though I expect.

It's definitely a lot of fun. A speed loader would make things a bit easier. They make 'em but I can't be bothered buying one. I'd rather buy a red dot sight for it. They make something that looks similar to how a red dot attaches to a P90.

I need to take it shooting... it's way off.

That is a sweet looking carbine, I have seen them in 9mm they are sweet we did a class for a small latino country one time and the 9mm was their choice in these they loved them, and they worked great for the guy's they used in vehicles.

Even the 22lr version was used during protection details with these guy's.
