BullCraft M240 Feed Block Replacement

A simpler connection for Bowden-spring feeding systems.

The BullCraft M240 Feed Block Replacement is a one-piece component designed to connect directly to a Bowden feed spring. It replaces multi-piece feed-block arrangements with a cleaner, more durable connection for compatible BullCraft M240 magazine systems.

Manufactured in-house from industrial SLS PA12 nylon, the feed block is lightweight, durable, and designed to provide reliable BB feeding without unnecessary adapters or additional components.

M240 Compatibility

Designed for BullCraft M240 magazine configurations using a Bowden-spring feed system on the Golden Eagle OEM M240B platform, including compatible replicas sold under the following brands:

• Golden Eagle M240B

• Lancer Tactical LT-240

• Cybergun/FN M240B models manufactured by Golden Eagle

• Matrix-branded M240B models based on the Golden Eagle OEM platform

This feed block is not designed for the older Echo1/JG-style M240 platform or magazine systems that do not use a compatible Bowden feed spring. Because M240 branding and magazine configurations can vary, contact us before ordering if you are unsure about compatibility.

M249 Magazine Adapter Kit

This feed block is also available as part of the complete BullCraft M240-to-M249 Magazine Adapter Kit for users who want to run compatible M249-style magazines on their M240.
