Our Thoughts
A quality weapon light deserves a quality mounting solution.
The factory mounts included with many weapon lights work well enough, but they're often bulkier than necessary and leave the light sitting farther away from the handguard than we'd prefer.
The Arisaka Offset Scout Mount solves that problem by pulling the light in tight to the rifle while placing it at a natural angle for activation. The result is a slimmer rifle that's less likely to snag on gear and more comfortable to shoot.
If you're building a serious defensive, duty, or competition rifle, this is one of those upgrades that seems minor until you use it—then you'll wonder why every light isn't mounted this way.
