Description
Product Details

This 3-Piece Modular Rail Set produced by BD is the essential accessory for anyone who owns an HK416 replica equipped with an SMR (Geissele Super Modular Rail) style handguard. Expertly crafted from CNC-machined metal alloy, these rails are incredibly durable while maintaining a negligible overall weight of approximately 45-47 grams.

Complete Configuration:
The package includes everything needed to customize the front end:

1x Long Rail: From approximately 95/98mm with 7 Slots, ideal for bipods or grips.
2x Short Rails: 55mm with 3 Slots, perfect for flashlights, lasers, or sling attachments.

⚠️ Compatibility Note:
These rails are designed for the proprietary SMR system that uses threaded holes directly on the handguard. They DO NOT mount on classic M-LOK or KeyMod systems. Make sure your rifle has the direct screw provision typical of 416 SMRs.
