Design and Features
The SIERRA 316/M-LOK pairs an A3 flat top upper—complete with white T marks for quick sight alignment—with a Magpul M-LOK handguard that keeps weight down and accessory options flexible. The hard coat anodized black finish resists wear in harsh conditions. The MOE Commercial stock with pistol grip offers familiar ergonomics for shooters transitioning from service-style platforms.
Barrel and Ballistics
The 16″ heavy profile barrel provides a balance between rigidity for accuracy and mass to manage heat during sustained strings of fire. The 1:9 rifling stabilizes common 55–69 grain projectiles used in 5.56 NATO, making the rifle suitable for defensive engagements and precision out to typical engagement distances for this caliber.
Controls and Modularity
With an A2 adjustable front sight and A3 flat top, the platform is optics-ready while retaining iron sight redundancy. The Magpul M-LOK system allows mounting weapon lights, backup irons, and short rails without unnecessary bulk. Capacity of 30+1 supports defensive readiness while remaining familiar to duty-style users. View product details and pricing
