Available in a multitude of sizes and styles, Sadlak’s Gas Blocks are a great option if you are building an AR or if you are just looking to upgrade. The Gas Blocks are available in .625”, .750”, .875”, or .936”. They also feature option such as Clamp-Style, Slip-On, Skeletonized, or Adjustable, and all attaching hardware is included. All Gas Blocks except for the Picatinny Rail Gas Block are Low-Profile. Finishes include Black Nitride or Manganese Phosphate. The Sadlak Gas Blocks Mounts securely to barrel with included setscrews. Clamp-on models squeeze around the barrel as you tighten the side-mounted setscrews. Slip-on models are anchored by setscrews on the underside. Low Profile fits under a free-float handguard and lets you use a longer on carbine-length barrels for a clean, streamlined look with more gripping surface. Extended Nose is like Low-Profile, but with an extended sleeve that covers taper pin holes left by the issue A2-style sight tower.
