Sako S20

History

Sako introduced the S20 rifle in 20 February 2020. At the date of its introduction, it is offered in two different main configurations, Hunter and Precision.[6]

Design

The S20 rifle features a steel receiver, which has Picatinny rails machined directly into it.[6] The bottom of the receiver is milled to a V-shape for mating it to an aircraft-grade aluminium chassis for its whole length. The receiver and chassis are attached with three screws.[6]

The cylindrical bolt features three locking lugs and is manufactured from stainless steel, and its handle is replaceable.[6] The bolt throw is 60 degrees.[4]

The barrel is cold hammer forged and is available in two different contours (grooved light and smooth semi-heavy) and comes in lengths of 20 and 24 in (510 and 610 mm).[6] The muzzle thread is ​5⁄8-24 UNEF (3A tolerance class).[6]

The stock, outside of the chassis, is made from high impact resistant polymer.[3] Both the front and rear parts of the stock are interchangeable and allow the use as a takedown rifle; the hunter variant has a thumbhole stock, while the precision variant has a sporter stock.[6] The stocks feature QD sling mounts, and the precision stock forend also features M-LOK accessory attachment points.[6] The length of pull is adjustable with spacers and the stocks feature adjustable cheek risers with a visible dial number.[6]

The trigger pack is installed in an aluminium frame and has an adjustable pull between 1 kg and 2 kg, and the trigger position can be adjusted by 7 mm. Both single stage and two stage trigger packs are available.[6] The safety blocks the firing pin when the safety is engaged.[6]

The magazines are detachable double stack single feed magazines, and they are available in two different capacity: 5 and 10 rounds for standard length cartridges (.243 Winchester, 6.5 Creedmoor and .308 Winchester) and 3 and 7 rounds for magnum cartridges (6.5 PRC, .270 Winchester, 7mm Remington Magnum, .30-06 Springfield and .300 Winchester Magnum).[6] The magazines also allow for longer-than-standard overall length for the ammunition.[6]

The rifles can also be fitted with a wide array of accessories, including muzzle brakes, a thumb rest, barricade stop and such.[7] Sako also manufactures a specific scope mount for 1 in (25 mm), 30 mm, 34 mm and 36 mm tubes, with three different height options,[6] or standard picatinny scope mounts may be used.

Sako guarantees a 1 MOA (0.3 mrad) accuracy for the rifle when using Sako factory ammunition.[6]
