The only good std to catch - Heresy Design Silencer Timing Device

timing was always my biggest grief with directional muzzle devices, fumbling with 20 shims trying to get it absolutely perfect, and then once you think its perfect and you torque it down it goes past what you expected and now you gotta restart the whole process, these really help with that and make it much more convenient, even though the biggest plus is kinda a one time install since you're not swapping them every day, i think they're 100% worth the price
