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

267:. 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.
600:«With the extremely light firing pin with only 4 mm travel this rifle got an extremely short locktime of 4 ms, i. e. that the bullet left the barrel after 4 ms after the shot had been released by the trigger. It is of utmost importance for the shooter that the bullet leaves the barrel as fast as possible after shot release to reduce aiming mistakes.»

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. However, magazines specifically made for biathlon differ by having a special base plate for ease of use with gloves.

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

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

Anschütz
Fortner rifles come with the Anschütz 5020 trigger which has an adjustable pull weight from 90 to 650 g (0.20 to 1.43 lb). 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

and produced since 2013 which has taken a lot of inspiration from the 1827 F biathlon rifle. While the two designs have similarities, like the locking mechanism designed by Peter
Fortner, their parts are for the most part not compatible. The stock inlets are however the same.

Other biathlon rifles formerly produced by Anschütz include the Anschütz 1427B Biathlon built on a Match 54 14XX action, the Anschütz 1827 (not to be confused with the 1827 Fortner) built on a Match 54 18XX action and the Anschütz 64R Biathlon built on a Match 64 action.
741:"The latest addition to the Anschütz product line − first seen at the 2013 SHOT Show in Las Vegas (Nevada, USA) last January − is the model 1727-F bolt-action, straight-pull rimfire carbine, conceived for both target shooting and varmint hunting practice."
