The better version of the cheaper option - Strike Industries AR Overmolded Enhanced Pistol Grip

Now this one is much improved. Grippy, good angle, secure storage. Where i ding this one is that strike had one with a hinged door but a steep angle. I wish they made that one with a 15 deg angle. Also, depending on your lower, the "beaver tail" might not sit flush. However in my instance it worked perfectly with my ke-9 lower.
