Arsenal Inc. SM-13 Universal Quick Release AK Side Rail Mount - SM-13

Arsenal SM-13 Universal Quick Release Scope Mount for AK Side Rails Black SM-13 UPC 810054130017

Product Description

The Arsenal SM-13 Universal Quick Release Scope Mount (SM-13) is an ultra-lightweight, battle-proven optics mounting platform designed specifically for AK-47, AK-74, and AKM rifles equipped with standard receiver side scope rails. Engineered to resolve the traditional optics mounting limitations of the AK pattern rifle, the SM-13 delivers a full-length 7.5-inch Picatinny top rail that extends over the receiver dust cover, allowing operators to run variable power scopes, red dot sights, magnifiers, or night vision optics with proper eye relief.

Precision CNC-machined from aircraft-grade 6061-T6 aluminum alloy and treated with a hardcoat anodized matte black finish, the SM-13 weighs a minimal 5.7 ounces while providing extreme structural rigidity. Featuring Arsenal's adjustable quick-release lever mechanism, the mount attaches directly to factory side plates and locks down tightly across variable side rail tolerances. The locking system guarantees return-to-zero capability when detached for field stripping, receiver maintenance, or transport.

Designed with an ultra-low profile framework, the SM-13 positions optics directly over the central axis of the barrel while maintaining clearance for iron sight co-witnessing or uninhibited iron sight usage when an optic is detached. The open center-channel design allows shooters to acquire standard iron sights under the optic mount on select setups, making the Arsenal SM-13 the gold standard for tactical, competition, and military-grade AK optic mounting.

Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fitment for factory AK-47, AK-74, AKM, SAM7, SGL, and WASR rifles equipped with standard Russian/Bulgarian pattern side receiver rails. Not compatible with Yugoslavian/Zastava N-PAP/O-PAP side rails or PSL/SVD dovetails.

1. Perform a complete firearm safety clearance check: drop the magazine, pull the charging handle rearward, and visually inspect the chamber to ensure the rifle is unloaded.
2. Unlock the quick-release lever on the bottom chassis of the SM-13 mount by rotating it to the open position.
3. Slide the mount from the rear toward the front onto the rifle's side receiver rail until fully seated.
4. Rotate the quick-release locking lever forward to the locked position. If the lever closes too loosely or cannot swing closed, press up on the locking plate stem and adjust the tension nut on the opposite side to set exact clamping force.
5. Ensure the mount sits square and parallel to the top dust cover without touching the rear sight block.
6. Mount your optic using standard Picatinny rings or QD bases, torque hardware to manufacturer specification, and verify 100% return-to-zero when removing and reinstalling the SM-13 assembly.
