Vortex’s Description: Simple, fast, effective. The push-button design of the VMX-3T engages and disengages the flip-mount, allowing the magnifier to lock in place. The result, 3x magnified or unmagnified views at will. Optics are fully multi-coated for optimal light transmission. Lightweight and tough, hard-coat-anodized machined-aluminum construction ensures durability. Internally nitrogen purged for reliable waterproof/fogproof performance. Ultimate magnified versatility for virtually any AR-height red dot sight.
The VMX-3T Magnifier will work with any of our red dots but it is not recommended for use with the prism scopes.
Allows for lower 1/3 or absolute co-witness mounting heights and is ideal for shooters who want to increase the effective range of their red dot sight.”
RKB Armory Opinion: “This is cleverly engineered. This would be good to leave on your rifle, or just use it for zeroing your red-dot.”
