Finally, a silencer adapter for Diana air rifle !

Diana pellet rifles are renowned for their quality and precision. Many sports or recreational shooters own one or more. But one request kept coming back : to be able to use a suppressor at the end of the weapon to shoot more silently. Wish granted here by our silencer adapter for Diana air rifle.

It is a custom part, that we manufacture in France on our CNC machines. We use aeronautical aluminum to make the part as light as possible. A black anodization protects it from corrosion and ensures the continuity of the finish of the weapon.

Its installation is very simple. Put off the original shroud at the end of your barrel, and replace it with our silencer adapter. A supplied Allen screw then allows you to secure the adapter on the little flat face of your barrel. It’s simple, fast and totally reversible.

Which Diana models are compatible with this muzzle adapter ?

We offer this silencer adapter for Diana air rifle in two different barrel diameters :

► 15 mm (0.59″) : for Diana Panther 21, Diana 20 T03, Diana 240, Diana 28…

► 16 mm (0.63″) : for Diana Panther 31, Diana 34, Diana 36, Diana 38, Diana 350 magnum classic…

So control your rifle with a caliper, and choose the one you need from the drop-down menu. The internal channel of our adapter is 7 mm (0.28″) wide, so it will be suitable for air guns in 4.5 mm (.177), 5.5 mm (.22) and 6.35 mm (.25).

Beware, the Diana 56 TH deviates from the rule. If you’re lucky enough to have one, you’ll have to redirect on our silencer adapter for Diana 56 Target Hunter.

Which suppressor to use on the silencer adapter for Diana air rifle ?

With this custom part, you’ll open the doors to .22 LR silencers originally designed for firearms. So no need to stick to dummy accessories for air weapons, you can use a real suppressor with internal baffles. To do this, we offer our muzzle shroud in two threads :

► 1/2 UNF (also known as 1/2×20 TPI). This is the standard thread in Europe for .22 LR silencers.

► 1/2 UNEF (also known as 1/2×28 TPI). This is the standard thread in the US for .22 caliber silencers in the broadest sense.

Choose yours based on the suppressor already in your possession, or the most common standard in your region of the world. Because yes, we manufacture in France, but we also ship internationally.
