The LWRCI™ Di is made with the same craftsmanship and design excellence that comes with every LWRCI™ firearm. Built from the ground up to be more than just another direct impingement rifle, the LWRCI™ Di delivers the quality every rifle enthusiast demands with innovation that's expected from LWRCI™. The innovative "keyless" bolt carrier design, combined with an operating system that is time-tested, makes the Di the perfect addition to the LWRCI™ lineup. And, since the ambi lower receiver is compatible with the rest of our IC family, you can upgrade your Di to our flagship, piston-driven IC just by switching out the upper.
