The Kinetic MREX™ Receiver extension provides the solution you’ve been searching for with your SCAR rifle platform. The MREX™ was designed to be a simple, durable, and lightweight.

    Ordered this product on Tuesday and received it on Friday. I don’t think that I have ever experienced the level of customer service that I have with KDG. At first glance I could not help but notice the level of quality that comes with the MREX. Engraving was very precise and there was no over shot on the fill. The cerekote on the MREX is clearly professionally done and not by your uncle Rick in his shed. It is also very light weight and will only add a couple ounces to your SCAR. Although there is a little weight added, the balance of the rifle is superb! The fit to the rifle is absolutely perfect. The slight gaps on the sides are equal on both sides and the gap to the barrel is spot on. If you are wanting a rail that will provide over-the-top quality as well as look great on your SCAR, this is the one!
