Yankee Hill Machine

The Sidewinder M2 is user serviceable which allows both the baffle and Nielsen device to be removed for cleaning and maintenance using the provided disassembly tool. The booster system has been completely redesigned and now uses the industry’s unofficial standard piston. The redesign also includes the ability to swap pistons without the use of tools thanks to a new rear cap. The front cap has been redesigned to allow for better engagement with the takedown tool to make the service process easier. YHM's Nielsen device enables flawless semi-automatic operation on all relevant host pistols. The Sidewinder M2 has 12 index points that allow you to adjust point of impact while our device remains attached to the host firearm. The average dry sound signature of the Sidewinder M2 9mm when testing to Mil-Std 1474D is 125 dB dry on a Glock G17 using 147gr. FMJ ammo. Shooting the suppressor “wet” will net even quieter results. - Caliber: 9mm - Weight: 8.8oz./10.2 w/Piston - Length: 8.2”/8.35” w/Piston - Diameter: 1.375” - Construction: Aircraft Quality Aluminum & 17-4 Ph SS - Mount: 1/2”-28 RH Piston - Decibel Rating: 125 dB - Full Auto Rated - Can be used on .300 BLK SUBSONIC with a 7.5" or longer barrel.
