SLR laid the groundwork for top-notch Gas Blocks when they created the Sentry 7. These adjustable Gas Blocks allow you to control how much recoil your firearm will produce, with the utmost repeatability and reliability. SLR uses a Melonite finish on these gas blocks as well as a proprietary alloy flat spring that can withstand blazing hot temperatures. There's no better place to purchase these blocks than at OpticsPlanet.com - where you get amazing customer service, the lowest prices around and free shipping on all of your orders over $49.
