Description
Product Overview
The Geissele Automatics Super Modular Rail (SMR) MK16 10.5" Handguard is built to deliver uncompromising rigidity, modular flexibility, and lightweight durability for demanding AR-15 shooters. Selected for its extreme strength-to-weight properties, this handguard is precision-machined from high-grade 7000 Series aluminum and finished with a rugged Type-3 Hardcoat anodization in black.
Designed to lock securely to your upper receiver using Geissele's updated barrel nut arrangement, the MK16 features dual anti-rotation tabs and set screws to prevent movement - even under harsh duty or tactical conditions. With a full-length M1913 Picatinny top rail and M-LOK mounting slots positioned at every quadrant, it provides maximum real estate for lights, lasers, foregrips, and optical accessories.

Frequently Asked Questions
Does the Geissele MK16 handguard include the proprietary barrel nut?
Yes, the Geissele Super Modular Rail MK16 comes complete with the updated proprietary Geissele barrel nut and necessary mounting hardware for installation onto standard mil-spec AR-15 upper receivers.
What barrel length works best with a 10.5" MK16 handguard?
A 10.5" handguard pairs exceptionally well with 11.5" or 12.5" AR-15 barrels, leaving enough barrel clearance to comfortably attach suppressors, muzzle brakes, or flash hiders without interference.
How does 7000-series aluminum compare to standard 6061 aluminum rails?
7000-series aluminum has a significantly higher yield and tensile strength than standard 6061-T6 aluminum. This gives the MK16 superior resistance to bending or flexing under hard impact, ensuring laser designators and iron sights retain zero.
Is this rail compatible with AR-10 or LR-308 upper receivers?
No, the Geissele SMR MK16 is engineered specifically for standard AR-15 / M4 pattern upper receivers and will not fit large-frame AR-10/308 platforms.
