Allow PREDATOR Custom Shop to build your AR-15 to your specs from the ground up. Mission-specific weaponry is our speciality. We know what works because we've been there! From our base model to our most popular models, the 5.56 CARNIVORE and the 5.56 DMR, each rifle is built one at time. We are not a production facility, we are a true custom shop taking the "black rifle" to new heights.
