M249 MONOLITH Feed Block
One piece. Zero nonsense. Built to feed.
The Bull Craft MONOLITH Feed Block is a streamlined, one-piece replacement for M249 platforms using Bowden spring systems. Designed to thread directly onto the Bowden spring, it eliminates bulky adapters, stacked plastic parts, and unnecessary failure points.
No gimmicks. No flex. Just clean integration and consistent feeding.
Manufactured from ultra-durable Nylon PA12 using our powder-to-solid SLS process, the MONOLITH Feed Block is built to handle sustained use and hard field conditions. Designed and printed in-house in Florida, this is a purpose-built solution that prioritizes reliability over complexity.
