The silencer adapter 1/2 UNF to M14x1 : for your European rifle

Our catalog includes many thread conversion parts, to solve any compatibility issues. The one you’ll find on this page is a silencer adapter 1/2 UNF to M14x1. It is therefore more naturally aimed at the European hunter or sports shooter.

It will allow you to transform the 1/2 UNF thread (also known as 1/2×20 TPI) of your rifle into a M14x1 thread (also known as M14x100 RH). You can then share a suppressor already in use on another rifle, or simply buy one more easily. This adapter also allows you to use, for example, a Browning T1 muzzle brake.

This product has a female end, and a male end. Simply screw the 1/2 UNF femal thread on the end of the rifle’s barrel. It can be secured by a few drops of thread lock. The M14x1 male thread then becomes available to accommodate the muzzle device you want.

silencer adapter 1/2 UNF to M14x1 compatibility

The 1/2 UNF is the standard thread in Europe for .22 LR caliber weapons. But it is also frequently found on hunting or sporting rifles chambered for center-fire ammunitions. We’re thinking here of .222 Remington or .243 Winchester. It is thus common to find it on threaded CZ 527 with light barrel.

We also met him on the Franchi Horizon bolt action rifle, this time in all calibers. This is not a problem for our adapter, which can also support magnum ammunition. Its inner diameter allows all bullets of 8 mm (.32″) diameter or lower.

In general, this accessory may be suitable for any rifle whose end of the barrel is threaded in 1/2 UNF. If the M14x1 destination thread doesn’t work for you, you can make another choice in our “custom silencer adapter for rifle” section.

A high-end piece

Machine threads to mount a gun accessory on a firearm is a tricky exercise. Ensuring perfect overall concentricity requires experience and state-of-the-art CNC machines. We have both.

Our team makes these adapters in small series, in a XC38 steel (also called C35 steel). We carefully control their dimensions, before and after hot bluing. A 100% French manufacturing, to preserve the accuracy of your weapon. Silencers and muzzle brakes have never been more comfortable than screwed on our adapters, and we are very proud of that.
