Upgrade your Arsenal SAM7K pistol or SBR with the Arsenal Inc. SM-22 Next Generation Scope Mount, engineered for rock-solid optic mounting on compatible side-rail equipped firearms. This low-profile, one-piece quick-release mount delivers reliable zero retention and versatile Picatinny real estate, solving the common challenge of unstable top-cover mounts that fail to hold accuracy under recoil.
Key Features
- Quick-release design with tension-adjustable steel locking mechanism for fast, tool-free attachment and repeatable zero
- 5.8 inches total Picatinny rail (2.9 inches per section) featuring 7 slots forward and 7 slots behind the rear sight for flexible optic placement
- Lightweight aluminum construction with precision CNC machining for durability without added bulk
- Low-profile silhouette that preserves iron sight co-witness and clears the rear peep sight on compatible models
- Attaches securely to the factory side scope rail for superior stability compared to gas-tube or dust-cover mounts
