There's an easy way to speed up your rifle reloads, and that's by incorporating a flared magwell into your fast-action drills. Having a flared magazine well makes it easy to guide that fresh magazine home, so you can get your rifle back into action faster than ever before. The KE arms KE-15 Billet Stripped Lower Receiver allows you to build your perfect rifle complete with this must-have feature. Each KE Arms KE-15 Lower Receiver is machined at the company's facility from 7075 billet aluminum. The company holds its receivers to tight tolerances within military specifications, so all mil-spec components will function in this lower, and the receiver is compatible with all M16- and M4-style upper receivers. To enhance its durability, the receiver is treated with an all-black, Class 2 hard-anodized finish. This particular KE Arms KE-15 Lower Receiver, in addition to having the flared magazine well, has been optimized to work reliably with SureFire 60- and 100-round magazines, as well as higher-capacity drums from Magpul and X Products.
