LWRC
The LWRC Skirmish AR-15 flip-up sight set brings no-frills dependability to your rifle's backup iron sights. Built for shooters who expect their gear to work reliably after thousands of rounds downrange, these aluminum and steel sights combine practical design with materials engineered to outlast harsh conditions. Whether you're running them as true backup to a primary optic or as your primary aiming system, the Skirmish sights are sized and weighted to stay out of your way—and to stay put when you need them.
What makes these sights stand out is the attention to detail in their construction. LWRC machines the main body from 7075 aluminum, a harder and more durable alloy than the 6000-series aluminum found in many competitor sights, then hard-coat anodizes it. The steel components are treated with NiCorr surface conversion technology to resist corrosion in wet, salty, or high-use environments. Internal bearings and detents are hard-chromed for the same reason—these parts are built to endure. The folded profile measures a half-inch tall, keeping your sight picture clean and your optic rail uncluttered. Sharp edges are rounded to prevent snags and cuts during handling and gear changes.
Operation is straightforward: raise either sight using basic gross motor skills (no fine dexterity required under stress), and they lock securely in the up position. A button on the left side of each sight lowers it. The sights mount to any standard 1913 Picatinny rail using a locking helicoil system that requires no additional thread lock compound. LWRC engineered this connection to absorb thousands of rounds of recoil and rough use without walking loose or failing.

No. LWRC's locking helicoil mounting system is engineered to hold without additional thread lock, though the system is durable enough to handle the recoil of extended shooting without loosening.
When folded down, the sights measure half an inch, keeping them out of the way of your optics and sight picture.
The main body is 7075 aluminum with hard-coat anodizing for strength and corrosion resistance. Steel components use NiCorr surface conversion treatment, and internal bearings and detents are hard-chromed to resist rust and wear.
