Figured I post my Mauser 22â€™s, these are excellent, extremely well made & highly accurate rifles. This is a ES340b single shot Mauser made in the late 1930â€™s. The sights are similar to the CZ trainers &the front sights are interchangeable. I have 3 different height front sights for the Mauser. The Mauser has an match bbl, adjustable 2 stage match trigger, adjustable rear sights & a walnut stock, just a beautiful rifle. This is my latest acquisition, a MAS45. MAS contracted Mauser right after the war (1945) to make training rifles for the army. Mauser put together one heck of a rifle for MAS, using many of the same parts that they used on their legendary 22 sporting rifles (ES340 series & 410 series). The MAS45 has a match bbl, adjustable 2 stage match trigger, adjustable rear sight & a birch stock. I have 2 different front sights for the MAS also. The MAs is new, still in Cosmoline, the parkerized finish is a dull grey color.. The different height front sights are for the different speeds on the 22 ammo, match 1080fps, standard velocity 1135fps & high velocity 1220fps. The speeds of the ammoâ€™s are approximate & by using the right front sight height the ladder rear sight will be on target @50 meters. On a side note, the CZ trainer ladder rear sight is made for SV (standard velocity 1135fps) ammo.
