Product DescriptionThe Ultradyne Mercury compensator is engineered for superior recoil reduction and to neutralize muzzle rise through a smooth, balanced release of blast energy. Progressive 90-degree side ports vent gases in stages, spreading out the recoil impulse for faster, more accurate follow-up shots. Built from 416 stainless steel with a durable salt bath nitride (black) finish, Mercury delivers compact, lightweight performance and is compatible with Ultradyne&';s Dynamount on-barrel sight system. It features a 5/8x24 thread pitch for .308 Winchester/7.62 NATO platforms and includes a shrouded timing nut for straightforward, precise installation. The .975-inch outside diameter provides a sleek, balanced profile.Product Highlights Superior recoil reduction with progressive 90Adeg side ports for flatter shooting Designed for .308 Winchester / 7.62 NATO rifles with 5/8x24 threaded barrels 416 stainless steel construction with salt bath nitride black finish for durability Includes shrouded timing nut for easy, repeatable installation Dynamount-ready on-barrel sight compatibility; compact .975" OD design Specs Type: Compensator / Muzzle Brake Thread Pitch: 5/8 x 24 Caliber Compatibility: .308 Winchester / 7.62 NATO Outside Diameter: 0.975 inches Material: 416 Stainless Steel Finish: Salt Bath Nitride (Black) Included: Shrouded Timing Nut Model: Mercury Brand: Ultradyne USA UPC: 850011462577 Manufacturer Part Number: UD10817 Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
