UTG Low Profile Flip-Up Front & Rear Sight Set

The UTG Low Profile Flip-Up Front & Rear Sight Set equips your AR-15 rifle with a rugged, dependable backup aiming solution. Precision-machined from aircraft-grade 6061-T6 aluminum and heavy-duty steel components, this complete backup iron sight (BUIS) set features a black hard-anodized finish engineered to withstand heavy recoil and harsh tactical environments. This premium iron sight combo is optimized to deliver consistent accuracy and a clean field of view on any flat-top rifle or pistol platform.

Engineered for Zero-Retention and Heavy Recoil

• Spring-Loaded Posi-Lock System: Features a robust push-button side plunger release mechanism that locks the sight towers securely into the upright position. This prevents accidental folding under heavy fire or field gear snags.
• Dual Aiming Apertures: The rear sight assembly incorporates a standard military-style double peep aperture. Flip between a wide opening for rapid close-quarters target acquisition and a narrow aperture for long-range precision targeting.
• Toolless Adjustments & Easy Zeroing: The rear sight features a tool-free windage adjustment wheel for fast fine-tuning on the fly. The front sight post utilizes a standard A2 post configuration that is fully elevation-adjustable with any standard 4-prong front sight tool.
• Super Slim Low Profile Design: Deployed at a standard 1.42-inch AR-15 center height, the sights sit at a compact 0.57-inch folded profile. This low-profile mounting base deck ensures they remain unobtrusive under your primary electronic optics and red dot scopes.

Precise Flat-Top Rail Fitment and Compatibility

This UTG front and rear sight combo utilizes a low-profile 3mm locking bolt and single Torx mounting deck to attach securely to any standard Mil-Spec 1913 Picatinny rail. They are designed to align on the same level plane, whether mounted onto a free-float handguard rail section or a receiver-height railed gas block.

• Perfect Fit Platforms: Smith & Wesson M&P 15, Ruger AR-556, Colt M4, Bushmaster, and custom AR-15 / LR-308 flat-top upper receivers.
• Specifications: Weight: 1.3 oz (Front) / 1.6 oz (Rear) | Rail Space Required: 1.25 inches deployed.
• Warranty Support: Backed by the official UTG Limited Lifetime Warranty for years of reliable service.
