Brevex in Suresnes, was created in the fifties by Mr. Polonsky, an engineer from Radom.
On Oberndorf machines which were repatriated during the occupation of the factory by the French troops and obtained from the MAS, he created two magnum actions, the M.300 for .375 H&H Magnum Rimless type cartridge and M.400 specially adapted to the .416 Rigby, .505 Gibbs and the like.
There are many differences between the Brevex and the Mauser magnum action, but the general mechanism is the same, even if not too many parts are interchangeable.
The Brevex is cruder but tougher than the Mauser and it need much more work to complete nicely.
In my opinion, it's the best action to build a professional rifle even if I like a lot also the old ZKK602.

Our front sights are made in house from a Recknagel blank.
On that Brevex .416 it's the plainest version of that kind of sight as, usually, we go further in the modeling of the ramp.

We use Lothar-Walther, Heym and Border barrels, depending of the project.

That particular .416 has been sighted at 50/100/150 meters.

Thank you for your interest.
