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 two scope bases machined directly into it.[6] The bottom of the receiver is milled to a V-shape for bedding into an aircraft-grade aluminium chassis for its whole length. The receiver and chassis are attached with three action 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 hammerforged and is available in two different contours (fluted light, or smooth semi-heavy) and comes in lengths of 510 and 610 mm (20 and 24 in).[6] The muzzle threading is 5⁄8-24 UNEF (3A tolerance class).[6]
The stock, outside of the chassis, is made from high impact-resistant fiber-reinforced polymer.[3] Both the front and rear parts of the stock are interchangeable and allow the difficult use as a takedown rifle; the hunter variant has a thumbhole grip, while the precision variant has a vertical grip.[6] The stocks feature QD sling mounts, and the precision stock fore-end 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 group is installed in an aluminium frame and has an adjustable pull weight of 1–2 kg (2.2–4.4 lb), and the trigger position can be adjusted front/back by 7 mm (0.28 in). Both single-stage and two-stage triggers are available.[6] The safety blocks the firing pin when the it is engaged.[6]
The magazines are detachable double-stack/single-feed magazines, and they are available in two different capacity: 5- or 10-round for standard short-action cartridges (.243 Winchester, 6.5 Creedmoor and .308 Winchester) and 3- or 7-round for long-action/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 (25.4 mm), 30 mm, 34 mm and 36 mm scopes, with three different saddle height options,[6] or standard Picatinny rings may be used.
Sako guarantees a sub MOA accuracy for the rifle when using Sako factory ammunition.[6]
