How Much Is a Calico M100 Worth? (2026 Value Update)

How We Calculate Used Calico M100 Value

The value of a Calico M100 is affected by its condition, variant, and accessories.

Condition and Value

Better-condition Calico M100 rifles always sell for more.

If you don’t know what your M100’s condition grade is, you’ll need to have it appraised. Most firearm stores or experts charge a fee for this, but we do it for free and online if you're a seller.

To see how we professionally evaluate your firearm (for free) and turn that condition into a payout, view our 3-step selling process for a guaranteed FFL offer.

How We Appraise Calico M100 Models

There are several versions of the M100 and their values can change based on the version.

Some include the M900 series here, like the Calico M950, Calico M951, and Calico M960. However, these are properly considered separately, being chambered for 9mm as well.

The true M100 series line of rifles is made up of .22LR plinkers. These are the Calico M100, Calico M100S, and Calico M100P (also called the 110).

Calico M100 Value

The average used Calico M100 is worth around $350 to $700.

This is the polymer rifle most people have seen, with its science-fiction-ish looks and a helical magazine. A delayed blowback carbine rifle, it typically comes with a folding stock.

Calico M100S Value

The average used Calico M100S is worth around $400 to $900.

The M100S was the earlier version of the rifle, fitted with a walnut-wood stock instead of polymer. Because of this, it tends to be more popular with collectors.

Calico M100P Value

The average used Calico M100P or M110 is worth around $300 to $450.

The Calico M110 or M100P is a compact-pistol version of the original rifle. Kitted out with a shorter barrel, it also omits the stock.

How Accessories Affect What We Pay for Your M100

Some accessories can improve the value of a Calico M100 rifle. Calico itself sells quite a few. Depending on the upgrade’s condition and your buyer’s interest, you may bump up the value.

Sights or Optics

As with the gun itself, better-condition ones can sell for more. If your gun is one of the earlier models, you might get bonus points for having a suitable vintage red dot on it. Something like a Weaver Qwik Point ($50 to $100) might appeal to collectors.

Value: Around 30% to 50% of the accessory’s brand-new value.

Extra Calico .22LR Helical Magazines

That crazy helical mag already boasts a capacity of 100 rounds. Despite that, a lot of buyers may still be interested in spare mags. Offer them if you can!

Value: Around $35 to $60 per spare mag.

Calico .22LR Scope Mount

The M100’s unusual design can make fitting some scopes a pain. If your buyer seems interested in adding a scope, offer this to make his job easier.

Value: Around $20 to $35.

Calico Rifle or Pistol Soft Case

If your buyer wants a tailored bag for toting the gun and you have a good-condition specimen of this, add it to the bundle. It will likely appeal to most people.

Value: Around $25 to $39.
