Compact Semi-Auto with Flip-Up Sights

The MF20's 20-inch barrel and 42.65-inch overall length make it ideal for brush hunting and confined spaces where longer shotguns become unwieldy. Flip-up front and rear sights provide quick target acquisition without requiring optics installation. The 5+1 capacity handles most hunting scenarios. California law restricts certain firearm types—learn more about exemptions at PC §32100 exempt revolvers to understand what applies to your situation. Browse our gun shop.

Frequently asked questions

Does the MF20 accept standard 20-gauge ammunition?

Yes. The 3-inch chamber accepts both 2.75-inch and 3-inch 20-gauge shells, giving you flexibility in ammunition selection for different hunting applications and shot loads.

What's the practical advantage of the 20-inch barrel length?

A 20-inch barrel reduces overall length to 42.65 inches, making the shotgun easier to handle in vehicles, brush, and tight hunting blinds compared to standard 26-28 inch barrels.

What is an FFL transfer in California?

An FFL transfer is when a federally-licensed dealer like TacticCAL receives a firearm shipped from another seller and processes California's required DROS paperwork to legally transfer it to you. Looking for gun store Cupertino? Visit us in Sunnyvale.
