The wide front wall baffling redirects gas to mitigate felt recoil and reduce muzzle rise. SI internal testing has typically seen a reduction average range (dependent on application) of 15-30% in felt recoil. This QUAD version in the SMTC line has a built-in anti-rotation system using the front tip of the pistol guide rod for most applications other than pistols with a flush guide/recoil rod system. With the clamp style design on the SMTC QUAD, timing the comp is simple including a secure and tight fitment. Originally designed for smaller compact, sub-compact and micro sized pistols, the SI styling of this QUAD pairs aesthetically well with most OEM and aftermarket slides on the market including full size pistols. Made from S45C steel with HRC40-45 heat treatment and a black oxide finish, the Strike Micro Threaded Comp – QUAD offers a smaller threaded barrel compensator option for your pistol with SI style. WARNING: For barrels with no shoulder, the o-ring included with this compensator will not work and cannot be used to help with timing. Please use Loctite® Threadlocker Red to secure compensator to barrel but apply an appropriate amount and not too much. Check this compensator as part of your routine maintenance. All installations must be done by a certified professional gunsmith only and properly tested to pass all safe and function tests. ny barrel with 1/2”x28 TPICalibers: 9mm and .357 SIG
