Geissele HK SMR 3-Hole Black Accessory Picatinny Rail 02-212HKB is designed specifically for use with Geissele HK Super Modular Rails, adding a genuine 1913 Picatinny-spec mounting surface where the SMR's M-LOK slots alone won't cut it.

This Geissele SMR rail accessory attaches through a 3-hole interface for a secure, repeatable accessory position every time it's removed and reinstalled. It allows the attachment of standard 1913 Picatinny Rail-mounted accessories such as lights and vertical grips, giving builders a hard-mount option without needing to swap the entire handguard for a different rail system.

Machined from milspec-anodized aluminum, this Geissele HK rail accessory carries 7 slots, enough length for most common accessory mounting needs without adding unnecessary bulk to the handguard.

Key Features:

• 3-hole mounting interface for Geissele HK SMR rails
• 7 Picatinny slots, 1913 spec
• Machined from milspec-anodized aluminum
• Black finish
• Compatible with standard Picatinny accessories (lights, grips)
• Secure, repeatable accessory position
• Sold as a single accessory rail section
• Designed specifically for HK Super Modular Rail platforms

This Geissele HK SMR 3-Hole Picatinny Rail gives an HK SMR build the hard-mount flexibility that M-LOK alone doesn't always provide.
