The thread protector for M17x1 rifle : for your Blaser R93, but not only !

The M17x1 (aka M17x100 RH) is an exotic thread. Most often, it is found on the Blaser R93 and Blaser R8 hunting rifles. It should then be protected with a thread protector for M17x1 rifle. If this protection cap can be supplied out of the box, it can also be lost, or missing on a pre-owned gun. You will find on this page the way to replace it.

But the M17x1 is also used by gunsmiths or importers to thread middle weight barrels. So we have already met it on Savage M10-TR sold in Europe, or even Mosin Nagant rifles. But since this type of post-production threading does not follow any rules, it can be found everywhere. Be careful though, our thread protector covers a maximum length of 16 mm.

The value of protecting its thread for a suppressor or a muzzle brake

When there are no accessories screwed on the muzzle of a firearm, protecting its thread is very important. So our thread protector for M17x1 rifle will preserve your weapon’s ability to host muzzle brakes and silencers for a long time. Shocks during transport or handling are no longer to be feared.

For this, we use XC38 steel, also known as C35 steel. Its excellent mechanical properties will also allow many screwing/unscrewing without threads damages.

Note that the custom part on this page can also be used to protect the male output of a custom silencer adapter for rifle.

The high-end machining of for your long gun

There is no “small product” here. We therefore put our CNC machine park and our know-how at the service of your need. Thus each thread protector for M17x1 rifle benefits from perfect dimensions and multiple quality controls.

In a drop-down menu to the right of the image, we offer you to define the finish of your thread protector. Choose “Knurling” if you want oblique grooves that makes screwing and unscrewing easier by hand. Choose “slick” if you want a smooth look, matching the barrel.

Also to the right of the image, you’ll find a second drop-down menu about the outside diameter. This is your chance to set up a thread protector for M17x1 rifle as close as possible to the original diameter of your barrel. A very popular aesthetic bonus among those who cherish the look of their guns.
