Strike Industries Cheek Riser for Dual Folding Adapter - Black - SKU: SI-FSA-CHEEKRISER - UPC: 793811765779
Product Description
The Strike Industries Cheek Riser for Dual Folding Adapter (SI-FSA-CHEEKRISER) is a drop-in polymer cheek rest accessory engineered specifically to enhance shooting ergonomics, optic alignment, and cheek weld consistency on the Strike Dual Folding Adapter (FSA) strut system. Designed to eliminate the discomfort of resting a shooter's face directly on an exposed metal adapter bar, this modular riser provides essential elevation for elevated optical red dot sights and LPVO scopes.
Precision-molded from high-impact composite polymer, the SI-FSA-CHEEKRISER features 5 distinct user-selectable position options—including flat and angled height profiles ranging from 10.25mm (0.40") up to 27.50mm (1.08") above the main strut bar. This versatility allows shooters to tailor head position precisely to match their specific eye relief and optic mount height.
Installation is toolless and fast via included ergonomic Triblade thumb screws and locking nuts. The clamp-on architecture secures tightly around the FSA strut frame, providing a rigid, non-slip cheek weld for PCCs, short-barreled rifles (SBRs), and Picatinny-adapted rifle platforms.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct drop-in fit for the Strike Industries Dual Folding Adapter (FSA) and FSA Single Folder stock strut assemblies. (Intended for use on registered SBR or rifle stock setups where cheek rests are legally permissible).
- Verify host firearm is completely clear, magazine removed, and chamber visually and physically confirmed empty.
- Select your desired orientation (flat profile vs. forward-slanted angled profile) and height position on the FSA strut bar.
- Place the two halves of the cheek riser around the upper edge of the folding adapter bar channel.
- Insert the thumb screw nuts into their hex cutouts and thread the Triblade thumb screws through from the opposite side.
- Tighten both Triblade thumb screws by hand until snug, then perform a shoulder alignment check with your optic to confirm optimal eye height.
