The Gemtech MIST-22 series of Integrally Suppressed 10/22 barrels. Using their patented G-Core Technology, Gemtech has created a lightweight, easily maintained, and unbelievably quiet package. The MIST-22 and MIST-22TD barrels are a great way to keep your rifle compact without adding the extra length of a standard suppressor. Both barrels use a match grade 22LR chamber. They feature a 1-16" RH Twist for use with commercially available bull barrel stocks, or, specifically engineered for use with the Ruger 10/22 Takedown Rifle. With either MIST-22 barrel the Absolute Sound Level is 114dB.
