Krink Handguard: The M-LOK Front End for the PSA Krink

Our Krink handguard is the HG-AKSU-4.70, the 4.70-inch M-LOK handguard made for the PSA Krink. It fits the PSA Krink in 5.56, 5.45 and 7.62x39 with conditions, and the .300 BLK Krink with conditions. It weighs 5.5 oz, has M-LOK at 3, 6 and 9, and clamps to the barrel rather than the receiver. The 3.2 oz GT-PKSU 1913 gas tube pairs with it on the 5.56, 5.45 and 7.62x39 Krink.

Where does our Krink build start?

At the front end: the handguard, with the GT-PKSU 1913 gas tube on top and a mag funnel below. The .300 BLK Krink takes the handguard but not the GT-PKSU.

What is in the Krink front end?

• HG-AKSU-4.70: 4.70", 5.5 oz, M-LOK at 3, 6 and 9. 1.3" inside and 1.5" outside diameter, 7075-T6 lower mount, Type 3 hardcoat. The 4.7" lower is common to every PSA Krink caliber.
• GT-PKSU: a 3.2 oz 1913 gas tube for the PSA Krink in 5.56, 5.45 and 7.62x39. It partly sleeves over the gas block and, per the product page, does not touch it.
• MW-AK-556: the 5.56/5.45 mag funnel, 2.0 oz. The 7.62x39 Krink uses the MW-AK-762. Both require the updated MMS lower mount with threaded side holes.

What Krinkov handguard length fits a PSA Krink?

The 4.70". Our 4.71" is the AKSU-optimal length; it fits with conditions on the Arsenal SAM7K-44, 104UR, 106UR and 107UR.

What about the .300 BLK Krink?

The HG-AKSU-4.70 fits it with a condition: the custom upper mount and gas tube for .300 BLK must already be factory-installed by PSA. We do not sell those separately, and the GT-PKSU is not for a .300 BLK Krink.

What stocks go on a Krink?

Our stocks and the arm bar, on the SM-1913 over the RSA-4.5, or on the SM-4.5 directly on the factory 4.5mm hinge pin.

What else do we make for the Krink?

• The RC-QD bridges the sling-loop cut and adds a front QD point.
• The HG-RM is for lasers. It removes free-float.
