LBE Unlimited ARPSR Front Sight Post AR-15/AR-10 Platform Black

The LBE Unlimited ARPSR Front Sight Post delivers reliable target acquisition for AR-platform rifles when optics fail or batteries die. This precision-machined sight post maintains zero under heavy use and provides the backup sighting solution that tactical professionals and competitive shooters demand.

What Makes This Different

Unlike standard A2 front sight posts that can loosen under rapid fire, the ARPSR features enhanced threading and a reinforced base design. The sight post incorporates improved windage adjustment mechanisms that hold settings through thousands of rounds. Military-grade steel construction resists impact damage and maintains structural integrity under extreme temperature variations.

Key Features

• Precision-machined steel construction for maximum durability
• Enhanced threading system prevents loosening during rapid fire
• Standard A2 height compatible with most AR-platform gas blocks
• Corrosion-resistant black finish withstands harsh environments
• Improved windage adjustment retention system
• Drop-in replacement for factory front sight posts
• Compatible with AR-15, AR-10, and M4-style platforms

Field testing demonstrates consistent point of impact maintenance through temperature cycles from -20°F to 140°F. The sight post performs reliably in competitive 3-gun matches, law enforcement training scenarios, and hunting applications where backup iron sights provide critical redundancy. Water immersion and sand exposure tests confirm the sight's ability to function when primary optics systems fail.
