Rifle owners who equip their guns with the Lancer Systems AR-15 Adaptive Magwell can experience faster, easier reloads, thanks to the unique design of this easy add-on product. The magwell attaches to the trigger guard of an AR-15 and expands the diameter of the magazine-well opening, making it easy to funnel magazine reloads into the gun. The Adaptive Magwell is machined from 6061-T6 aluminum. One-piece designs weigh 2.2 ounces, and two-piece setups weigh 2.8 ounces. The magwell cannot operate with Magpul PMAG Gen 3 magazines.
