How the heck are those Czech's putting a sling on the EVO's? The rear is made into the plastic reciever and the front appears to only except the HK style clips. I know PMM make some QD points and will consider that if any of you have real life experience with them. I've heard the Strike Industries S3 is a good option but I really like using QD. Anyway, let me know what setup you guys are using.
