The MOD AR-15 Gripis truly the first of its kind. A drop in grip replacement for the AR platform, it has been extensively tested and designed by Tyrant Designs CNC. It is a very lightweight and modular (hence the name) Aluminum and Polymer Composite AR-15 grip. The Body of the grip is made from aerospace grade 7075 Aluminum, then finished in a type III hardcoat black anodize. The front and back straps of the grip are made from a polymer composite, are fully removable, and are offered in different sizes as well as designs. We will continue to come out with new strap options as well as strap designs, making this one of the most modular AR-10/15 grips available. With this design the operator will not have to compromise form vs. function. We have specifically designed this grip to feel just as comfortable as any other polymer grip, but with the American craftsmanship every rifle deserves. Please join us in celebrating the MOD Grip and the end of crappy plastic grips!Fitment:AR10 AR15 M16 AR.308 M4Features:Durable (polymer straps and aluminum body, near indestructible)Comfortable (chamfered edges for a smooth feel)Temperature variation resistentDeep ribbing for easy installationCNC engraved logoBeveled edge near trigger guardInstall kit includedIncludes:1 grip screw4 strap screws2 L-keys
