A thread adapter to screw American standard muzzle devices on European threaded rifles
When it comes to barrel threads, our silencer adapter M18x1 to 5/8×24 TPI can circumvent the geographical standard problem. In Europe, hunting or tactical heavy-barrel rifles usually have M18x1 thread. But in the U.S.A., the thread dedicated to .30 calibers is rather the 5/8×24 TPI. It is therefore very often required to convert the thread of the weapon to access the muzzle device you want.
The first idea is to open up the spectrum of compatible suppressors. But this thread adapter can also be used for a muzzle brake or a flash hider. Overall, it allows to screw any accessory in 5/8×24 TPI onto an M18x1 rifle.
Beware, not all European rifles are threaded in M18x1 (also known as M18x100). Thus, the ones with sporting barrels are often in M14x1. If this is the case of yours, but you still want to use a 5/8×24 TPI silencer, choose our silencer adapter M14x1 to 5/8×24 TPI.
On which long guns can I use the silencer adapter M18x1 to 5/8×24 TPI ?
European heavy-barrel rifles threaded in M18x1 include the Tikka T3X Sporter and Tikka T3X Tactical. Other examples include the Browning X-Bolt Varmint or the CZ 557 Varmint. It is also the standard of the legendary Sako TRG 22 and 42. Or of the new rising star of long range shooting : the Bergara B14.
Still make sure that yours is in M18x1 before placing your order. If it’s not, we can of course make you a custom silencer adapter for rifle.
The adapter sold here has an external diameter of 22 mm (0.86″). This allows most silencers that partially shroud the barrel, in addition to traditional silencers. Beware, this statement is no longer true in the hypothesis of a rifle with front sight.
Compatibility of the silencer adapter M18x1 to 5/8×24 TPI
Regarding ammunitions, the M18x1 is generally associated with the .30 and approaching calibers. This covers non-exhaustively the .308 Winchester, the .30-06 Springfield, the .300 Blackout and the 7.62x54R. But it is also sometimes found on smaller-caliber long guns: 6.5 Creedmoor, .243 Winchester or even .222 Remington.
Our silencer adapter M18x1 to 5/8×24 TPI has an internal diameter of 9 mm (.35″). It will therefore be suitable for all bullets under this diameter. It is not afraid of the pressure of Magnum calibers, and can therefore be used on a .300 Winchester Magnum or .338 Lapua Magnum rifle.
