The M249 "Featherweight" is simply inadequate in its factory configuration.

The stock feed block is responsible for misfiring, magazine incompatibility, and allowing BBs to pass through the magazine-well into the receiver.

The Gen2 AntTech Improved Feed Block for "Featherweight" M249 sports all of the features of the Gen1 and more!

• Easily replaceable reinforced Feed Plates
• Two different length Feed Plates for optimal mag compatibility
• 5% wider feed track inner diameter
• Broader curvature of the feed track
• Detachable BB shield
• A&K/ C.A. Spec M249 Hop Up Compatibility
• Break away wire channel for use with BullGear KIT Box Mags
