A silencer adapter for HK MR223 or HK MR308

Our silencer adapter M15x1 to M14x1 is primarily aimed at owners of an HK MR223 or HK MR308 rifle. But not only ! German arms manufacturers are very fond of M15x1 threading. It is thus found on Blaser R8 or Blaser R93 hunting rifles. It is also common on Haenel productions like the Jaeger 10 Pro. Further north in Europe, it is also sometimes used for Sako A7 or some Tikka T3.

But in the rest of Europe, long guns with a light barrel mostly use the M14x1. It is therefore normal to find suppressors or flash hiders in this thread more easily. That’s why we offer this silencer adapter M15x1 to M14x1: to open up more possibilities.

Features of the silencer adapter M15x1 to M14x1

The female thread in M15x1 is screwed directly to the end of your barrel. The accessory is perfectly cylindrical, so you won’t need to index it. No shim kit or crush washer needed. Our adapter is ready to go as soon as you get it, but a few drops of thread lock to secure its tightening are always welcome.

This thread converter can be used for a suppressor, a muzzle brake or a flash hider. In addition, the 22 mm external diameter easily allows accessories that cover part of the barrel. Here we think about the H2 A-Tec silencer, pretty popular in northern Europe.

When it comes to calibers, all bullets under 8 mm (.32″) are usable. This includes of course the wide range of .30 calibers (.30-06 SPRG, .308 Win, .300 Win Mag…) but also smaller sections (.243 Win, .223 Win, 6.5 Creedmoor…). Don’t worry about pressure: everything your silencer can handle, our adapter will too.

Our silencer adapter M15x1 to M14x1 : a high end custom part

Manufacturing thread converters is our specialty. We make them out of XC38 steel, also called C35. To preserve the accuracy of your weapon, we take special care to the concentricity of male and female threads. We work on the latest generation of CNC machines, and operate the strictest quality control.

While the M14x1 is the most common thread for European light-barreled rifles, there are others popular ones. So we also offer a silencer adapter M15x1 to M18x1 (for heavy barrel’s accessories) and a silencer adapter M15x1 to 5/8×24 TPI (for accessories threaded the American way).
