Mauser Model 66
Notes: Introduced in 1965 (with production beginning in 1966), the Model 66 is a bolt-action sporting rifle which comes in four basic models (or groups) and several variants. It features a short-throw bolt action, even when chambering the long rounds the Model 66 normally uses; this is achieved by locating the magazine between the trigger and the bolt, and by telescoping the bolt and bolt carrier. The weapon has iron sights, which may be removed and replaced by others if desired. It is also drilled and tapped for a scope mount. The stock is of walnut, with a half-length fore-end and a rubber recoil pad on the butt. It has a number of nice touches, such as an ebony or rosewood pistol grip wrist cap, a rounded rosewood fore-end cap, a checkered pistol grip wrist and fore-end, and a set trigger as standard (with a conventional trigger available upon request). Variants include the Model 66ST Stutzen (known as the Model 660 Ultra in the US), with a shorter 20.85-inch barrel (as opposed to the standard 23.6-inch barrel); the Model 66SM, with a Monte Carlo-type stock, deeper pistol grip wrist, and a Schnabel fore-end tip; it is identical to the standard Model 66 for game purposes. The Model 66S and Model 66SM Magnum are virtually identical to the Group IV standard Model 66s, but use 25.6-inch barrels, heavier bolts, and deeper magazines. The Models 66D and 66SD are deluxe versions of the standard rifle, identical for game purposes to the standard M-66.
The Mauser SP-66 Sniper Rifle (see German Sniper Rifles) is a heavily-modified version of the Model 66.
This is the .270 version,
