History

Anschütz has been producing biathlon rifles since 1976. The design of the 1827 Fortner action dates back to 1984, when Peter Fortner was having beers with

. Angerer expressed that he wanted a rifle which could match those used by Soviet and East German competitors. Fortner took the challenge and within a few months developed and patented what was to become known as the "Fortner action", with the 1827 Fortner introduced around 1984. The Fortner action is produced by Fortner Waffen under licence from Anschütz, and are marketed as Anschütz rifles.


Technical

Anschütz Fortner rifles come with the Anschütz 5020 trigger which has an adjustable pull weight from .Test Report: Anschutz 1727 Fortner .17 HMR Sporter – Sporting Shooter
/ref> The trigger can be adjusted to function either as a single or two stage trigger. The straight-pull mechanism uses seven hardened steel ball bearings evenly positioned around the rear of the bolt as locking elements. When the bolt handle is pushed forward, it moves a locking piece called the bolt clamping sleeve forward, forcing the ball bearings out to lock into a negative recess in the receiver. There are no matching negative shaped (concave) recesses in the receiver. That would be very hard to practically produce at the required precision level. Instead there is a simple continuous semi-round groove machined for the ball bearings to lock into. The locking piece retracts when the bolt handle is pulled back, allowing the locking bearings to retract into the bolt body so the bolt can open. The bolt can be classified as a semi-rigid type, since the locking elements are movably mounted on the bolt. This mechanism was patented in 1984 and has expired. The 1827 F has a

, an optional firing pin buffer (also called "Dry Fire Donut") must be installed by the user. The barreled action is produced by Fortner Waffen, and has a length of 730 mm. Although having been produced for nearly 40 years, the barreled action has not changed very much. All accessories and other parts are compatible across all production years. For example, triggers from any production year are technically the same and compatible. The main improvement has been in the barrel, as some early models featured non-nitrated barrels, but these are rare to find. Barrels are not threaded but press-fitted to the receiver, and can be changed by a competent

. Like other high end .22 LR competition barrels from Anschütz, the muzzle is choked, presumably to achieve better performance in cold weather. The action has a safety catch located on the side of the receiver, with "S " indicating ''Sicherung'' (meaning "the safety" in German) and "F" indicating ''Feuer'' (meaning "fire" in German). The factory stocks are produced by Anschütz, and the stock design has changed a bit during the years. The current Anschütz design has an adjustable cheek rest and length of pull so that it can be fitted to different athletes. It has not been uncommon for athletes to purchase custom or aftermarket stocks from other brands, and these are not always adjustable. 1827 F magazines are compatible with curved .22 LR magazines for the Anschütz 1400 and 1700 sporting series, as well as the magazine fed version of Anschütz 54 and 64 target actions.Magazines – Anschutz – Anschutz .22LR bolt action – RifleMags.co.uk

Trivia

Anschütz barrels have been known for their high quality, and was used in production of some Izhmash Bi 7-3 biathlon rifles in the 1990s. These rifles are designated BI-7-4A.The history of Russian biathlon rifles
