Product DescriptionThe KAK Industry Plan B A2 Flash Hider is a suppressor-ready muzzle device designed around the Plan B mounting system. It uses a taper followed by threads to promote repeatable lockup and a proper seal between the muzzle device and suppressor adapter. Built from 17-4 stainless steel with a durable nitride finish, it features milled rear flats for easier installation. For best results, KAK recommends Rocksett during installation and 2025 ft-lbs of torque. Note that some suppressor manufacturers may not honor warranty claims when muzzle devices from other brands are used with their suppressors.Product Highlights Plan B-compatible taper-and-thread design for repeatable lockup and improved sealing 5/8x24 thread pitch with .375inch bore for proper fitment on compatible barrels 17-4 stainless steel construction for strength and long-term durability Nitride finish for enhanced wear and corrosion resistance Milled rear flats (3/4inch) to simplify installation and removalSpecs Brand: KAK Industry Product Type: Plan B A2 Flash Hider (muzzle device) Thread Pitch: 5/8x24 Bore Diameter: .375inch Overall Length: 1.850inches Material: 17-4 Stainless Steel Finish: Nitride Weight: 2.5 oz Installation Feature: Milled rear flats, 3/4inch Recommended Installation: Rocksett; 2025 ft-lbs torque UPC: 811163036276 Manufacturer Part Number: 411-2103-006Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
