Introducing the latest addition for 2021 - YHM's suppressor gas block, specially crafted for shooters seeking an affordable solution to optimize their AR for suppressed shooting. This gas block boasts a gas port hole that's 50% smaller than the standard, effectively reducing "port pop" and minimizing blowback to the shooter. The result, a much more enjoyable suppressed shooting experience. Keep in mind that due to various factors like barrel gas port size, length, Cal, suppressor design and ammunition, fine-tuning may be required to match your specific setup. Designed for exclusive use on a host firearm with an attached suppressor, YHM's suppressor gas block is your gateway to a more refined and satisfying shooting experience.
