Strike industries make some of the best firearm accessories out there, and their X-Comp range of muzzle devices are excellent. Apart from muzzle breaks, and flash hiders, they also make thread protectors, which are very important, yet quite overlooked.

The pistol caliber carbine class of firearms has gained a lot of popularity over the past few years. They allow you to extend the range of normal pistol calibers and offer a much more stable shooting platform, making them ideal for self-defense. If you have a 9mm PCC, like the CZ Scorpion EVO, the Strike X-Comp Thread Protector for M18x1 RH is an excellent option.

Made Specifically for The CZ Scorpion EVO

The CZ Scorpion is probably one of the most popular pistol-caliber carbines in the market. Where most 9mm pistol caliber carbines in the market have the standard 1/2x28 thread pitch, the CZ Scorpion used a click stop muzzle attachment system, which is really efficient and makes timing muzzle devices a lot easier. However, with the click stop threads, the CZ Scorpion has M18x1 RH threads, finding thread protectors for which can be a little difficult. So, the X-Comp Thread Protector for M18x1 RH from Strike Industries is a really good option.

Protects Barrel Threads

The barrel threads on your muzzle can get damaged if they are exposed, in some cases by venting gasses, and especially if the firearm falls or hits something. Damaged threads can make it difficult to properly mount muzzle devices, so if you don't have any compensator, muzzle break, or flash hider mounted onto the barrel of your pistol caliber carbine, you should make sure the threads are covered, which can prevent damage. A thread protector like this one can also protect the crown of your barrel from damage.

Durable Construction

Most people suggest that you should take the thread protector off your barrel when you are firing it because it can easily come loose after a few shots, and end up damaging your accuracy and deteriorating your barrel threads as well. This is not something you have to worry about with the Strike Industries X-Comp thread protector. It is safe for live fire with the 9mm rounds.

Moreover, with the durable AISI 1144 steel construction, the thread protector can take the toll of 9mm shots. It also has a bead blasted QPQ finish, which aids in its durability, and makes it corrosion resistant.
