The Presma 15" Super Light free-float handguard is a lightweight M-LOK rail for AR-15 / 5.56 rifles. CNC-machined from 6061 aluminum and finished in a matte black hardcoat anodize, the complete assembly weighs just 11.9 oz with the barrel nut — a real weight savings over quad-rail and heavier free-float designs, without giving up mounting real estate.

Specs and features:

• 15" free-float M-LOK handguard for AR-15
• 11.9 oz total weight (handguard + barrel nut)

Compatibility: AR-15 upper receivers with a standard barrel-nut interface. Compatible with low-profile gas blocks (clears the 1.358" ID). Not compatible with A2 front sight bases or FSPs — those require the block/sight to sit outside the handguard. Verify your gas block outer diameter and barrel journal clear the ID before installation.
