The Strike Industries X-Comp Element C is designed for the CZ Scorpion EVO, and its click stop muzzle device locking system. However, it is not limited to the CZ Scorpion platform and can be used on any other 9mm pistol caliber carbine, with the help of the Strike X-Comp Thread Adapter Kit.

Using this thread adapter kit, you can make your PCC compatible with any other Strike Industries family of X-Comp M18x1 RH thread pitch muzzle devices.

Ideal for Most Pistol Caliber Carbines

Originally, the X-Comp Muzzle devices were designed for the native M18x1 RH thread pitch of the CZ Scorpion EVO; however, for 9mm, there are multiple thread pitches that can be used, and Strike Industries water to make a universal adapter, that would allow their X-Comp muzzle device to fit on any Pistol caliber carbine.

That's where the Strike Industries X-Comp Thread Adapter Kit comes in. It is available in different thread pitches to make installation on any PCC super easy and convenient. You can get a 1/2x28 to M18x1 RH, which is the most common thread pitches used on most 9mm pistols caliber carbines, with the exception of some HK and Glock Pistols. Still, most 9mm PCCs use the 1/2x28 thread pitch. The 5/8"x24 is also quite common, and you can get a version of the X-Comp threat adapter for that as well.

Even for the not-so-common thread pitch patterns, like the M13.5x1LH thread pitch on the Sig Sauer MPX, you can use a version of the X-Comp thread adapter that makes it compatible with all Strike Industries X-Comp Muzzle Devices.
