BriceOnCnc 4.7MiB Updated November 1, 2025, 8:43 AM Released October 31, 2025, 9:56 PM

Advanced Mods for Decker 380, Version 3.0.2

This distro contains mods for improving certain features of the Decker 380. (Mods are listed further below.)

Typically, Decker parts are simply printed – then immediately assembled. In contrast, you’ll be using more advanced methods than just printing and assembly. And the results are worth it. Don’t worry: these improvements are not hard to perform. In some cases – it’s just clever use of a round chainsaw file (not kidding!).

What improvements are included?

More durable Bolt, improved cycling, side cocker version is included. Many issues addressed.

Firing pin assembly upgrades. Prevents common firing pin issues.

Bolt cover with improved fastener design. Reduces rubbing on the Bolt.

Barrel assembly improvements. Barrel no longer works loose. Rotation issues have been eliminated.
