The silencer adapter 5/8×24 TPI to M15x1 : a solution to switch from the American thread to the German thread

On this page you will find a silencer adapter 5/8×24 TPI to M15x1. It meets a specific need : to transform the 5/8×24 TPI thread of your firearm into an M15x1 thread. Then you will be able to use a suppressor originally designed for German rifles, on your US rifle.

The most common case is that of the sports shooter who acquired an HK MR308, and the matching .30 caliber silencer. Let’s say he then turns to a .308 Winchester bolt action rifle to get better results in precision shooting. The heavy barrel of his new gun has a good chance of having a 5/8×24 TPI thread. If he wants to continue using its initial suppressor, it must then convert this thread using a silencer adapter 5/8×24 TPI to M15x1. You just found it.

Of course, this thread converter can also be used in many other circumstances. Generally speaking, it will be compatible with all 5/8×24 TPI threaded long guns. It can therefore be used, for example, to mount an Heckler and Koch G28 flash hider on your Smith & Wesson M&P10.

How does this silencer adapter work?

Like any muzzle device, this thread converter screws to the end of your rifle. No indexing is required, so you won’t need crush washer, shim kit or locking nut. On the other hand, a few drops of thread lock are always welcome to secure it.

A knurling on the adapter’s body allows you to screw it by hand. Its external diameter remains small (.89″), so you can choose a silencer partially covering the barrel (check the compatibility of the model envisaged).

The internal diameter of this thread converter is 9 mm (.35″). It will therefore be compatible with most common long-gun calibers (.308 Winchester, .30-06 SPRG, 6.5 Creedmoor…). Our adapter is also not afraid of Magnum calibers (.300 Winchester Magnum, .338 Lapua Magnum…). Moreover, the inner diameter of a silencer adapter is never too large. So it will also work perfectly on a weapon in .223 Remington or .243 Winchester.

The silencer adapter 5/8×24 TPI to M15x1 : a premium muzzle device

Silencer adapters are our specialty. We have been making them for many years, so we are very aware of the concentricity imperatives that this entails. We carefully control ours at every stage of their production. All operations are carried out on the latest generation of digital control machines.

For flawless durability, we work with an XC38 steel (also known as C35). We then ship the raw adapters to a surface treatment professional so that they undergo hot bluing in the rules of the art. We finally practice one last quality control before sending each order.

The combination offered on this page (5/8×24 TPI to M15x1) may not be the one you need. To change one of the settings, we invite you to visit our page dedicated to the custom silencer adapter for rifle. Thus you’ll be able to order the one you need, for the same price!
