An M15x1 thread protection for your hunting or sports rifle

On the market, there are many rifles with threaded barrel to host a muzzle device. Then a silencer, a flash hider or a muzzle brake can be screwed on it. But sometimes, the accessory or the original thread protector is lost. The temptation then exists to leave its thread bare, since this does not interfere with shooting. But you must not yield to it. If your thread is vulnerable to shocks, you take the risk of not being able to use it after a fall or hectic transport. That’s why we offer this thread protector for M15x1 rifle.

To best match your long gun barrel, we offer this part in different external diameters, knurled or not. Use the drop-down menus to the right of the image to choose the settings that suit your need.

Why choose our thread protector for M15x1 rifle ?

We machine all our thread protections in a XC38 steel, also known as C35. This ensures perfect resistance to repeated screws/unscrews. Something that could not offer an aluminum or plastic part. We manufacture them on CNC machines, with the same care we take to our silencer adapters. Made in France from start to finish, and we are proud to ship all over the world.

Each thread protector receives a hot bluing in accordance with the rules of the art. For this we use an industrial subcontractor, specialized in high-end surface treatments. Of course, he’s also French. We can thus offer our customers a perfect and durable finish, matching the greatest hunting or sports shooting weapons.

To make handling easier, our thread protector for M15x1 rifle also benefits from precise external knurling.

With which long guns is this custom piece compatible?

M15x1 threading is not the most common in the world of firearms. However, it is often found on German weapons. Examples include Blaser R93 and Blaser R8 rifles with standard barrel, or Haenel long guns such as the Jaeger 10 Pro. Shooters who prefer military equipment also know it as the default thread of Heckler and Koch assault rifles, such as the excellent MR223 and MR308.

More broadly, this protective ring will be suitable for any barrel with M15x1 thread on 16 mm (0.63″) or less. Note that this thread is also referred to as M15x100. If this is not the case with yours, feel free to check out our other options in our thread protectors section.
