This sight system is a compact powerhouse, designed to offer the reliability and functionality that Magpul is known for. Significantly reduced in size, the MBUS 3 Front Rifle Sight stands at a mere 0.44 inches high when folded and measures 1.15 inches at its widest point. With aesthetics inspired by the MBUS Pro but constructed from Magpul's durable, impact-resistant polymer, this sight offers a perfect blend of lightweight design and extreme durability. The spring-loaded technology allows for quick deployment with an ambidextrous push-button, ensuring you can be ready in any situation. When deployed, it sits at the standard AR-height. The MBUS 3 Front Rifle Sight also features tool-less elevation adjustments and a dual-width enhanced front sight similar to the MBUS Pro, allowing for precise aiming without the need for additional tools. Please note that this sight cannot be mounted on a railed gas block due to potential heat issues. It must be mounted to a railed forend on the same plane as the receiver rail and is not compatible with MOE Hand Guards. Experience the next level in back-up sight systems with the Magpul Industries MBUS 3 Front Rifle Sight, offering unmatched reliability and versatility for your rifle.
