Springfield KUNA Extended Handguard

Product Description

NOTICE: LIMIT ONE (1) PER CUSTOMER UNITIL INITIAL DEMAND HAS DIED DOWN. YOU WILL NOT BE ABLE TO CHECK OUT WITH MORE THAN ONE IN YOUR CART.

Elevate your Springfield KUNA with the Extended Handguard from SKYE – a precision-engineered upgrade that delivers lightweight performance, unmatched versatility, and seamless compatibility. This handguard mounts to your KUNA receiver using the included hardware, requiring zero permanent modifications and leaving your barrel untouched. Crafted in the USA from premium nylon, it adds just 3.6 oz of weight and is designed to minimize the transfer of the heat to the shooter. It extends 2.75" past the front of the receiver for a more ideal forward grip point.

Key Features:

• M-LOK Versatility: Strategically placed slots on the sides and bottom let you customize your setup with lights, lasers, grips, and more – unlocking endless configurations for tactical ops or range days. Shorter Mlok screws may be needed depending on the diameter of suppressor used.
• 1913 Picatinny Top Rail: A continuous top rail extends the KUNA’s factory top rail, providing seamless mounting for backup irons, optics, or additional accessories without gaps or alignment issues. Factory flip up front sight remains unaffected
• Ultra-Lightweight Comfort: Minimize added weight for effortless handling and reduced fatigue during prolonged sessions, while the ergonomic profile ensures a secure, natural hold. The polymer is not only lightweight, but also prevents the heat transfer associated with aluminum handguards.
• Suppressor-Ready Design: Accommodates suppressors up to 1.65" in diameter, keeping your build compact and quiet. 
• Streamlined Aesthetics: Delivers a sleek, modern look that enhances both form and function, perfect for recreational plinking or high-stakes precision.

Specifications:

• Length: 6.5" (2.75" extension past receiver)
• Height: 3.1"
• Width: 2.2"
• Weight: 3.6 oz
• Material: Premium nylon

Priced at $180, this handguard isn't just an accessory – it's a game-changer for KUNA owners seeking superior ergonomics and modularity. Made in the USA

WARNING: This handguard is designed to be used with a suppressor or muzzle extension. DO NOT fire your KUNA without using either of those while the handguard is installed. Failure to do so could result in injury or damage to the handguard and/or installed accessories. Haga Defense recommends the Midwest Industries "Blast Can" for direct thread or the Angstadt Arms "Blastwave" for Tri-Lug setups. Both are shown as an optional add-on.

Thermal Performance and Material Considerations: Customers have occasionally raised questions regarding the potential for sustained suppressor heat to adversely affect the polymer handguard during extended or high-volume firing schedules. In-house testing, combined with years of real-world use of similar polymer over-suppressor handguard systems across multiple platforms, has shown no instances of melting, deformation, or material degradation under normal to heavy use conditions with pistol caliber rounds. While the handguard is engineered to withstand the thermal loads typically encountered in operational and recreational shooting, extreme sustained fire (e.g., prolonged full-automatic or high-round-count mag-dump scenarios with minimal cooling intervals) may exceed the design parameters of any polymer-based handguard. In such cases, elevated temperatures could potentially affect the material, especially if an appropriate air gap is not maintained between the suppressor and inside of the handguard to promote cooling. We recommend exercising appropriate caution and sound judgment during unusually demanding range sessions, particularly in high-ambient-temperature environments with prolonged full-automatic fire. As with all firearm components, the end user assumes responsibility for employment beyond standard use cases.

WARNING: Polymer M-LOK Warning Max Torque: 15 in-lbs Overtightening M-LOK accessories will damage the polymer slots. Do not exceed 15 in-lbs. Use a torque wrench when possible. Ensure T-nuts rotate 90° into the locked position. Products with damaged slots cannot be returned or exchanged.
