Sako was established in 1921 to build firearms for Finland's Civil Guard and played a key role in that country's defense in WWII. Lapua began cooperating with Sako on the .338 Lapua cartridge in 1988, and this eventually yielded the TRG-41 sniper rifle. Sako updated the design and dubbed it the TRG-42, which the Finnish Army adopted in 2000.
The TRG-42 has a Garand-style safety, three-way adjustable trigger, and magazine release located forward of the trigger guard. The bolt catch is visible rear of the ejection port.
The TRG-42 has a 27 1/8-inch tapered contour cold-hammer-forged barrel. The chrome-moly barrel may resist throat erosion batter than stainless steel. The TRG-42 is also available with a stainless steel barrel.
The TRG stock comprises two shells which screw onto the aluminum profile: one for the fore-end, and one for the butt-stock. Because these stock shells connect directly to the aluminum profile, there is no need for bedding and the stock does not affect accuracy. A folding stock rear shell is available for the TRG series.
The TRG stock provides quick-detach sling swivel mounts on both sides of the butt-stock; the front of the sling attaches to a sling mount on either the top or side of the rifle. The TRG detachable magazines are double stack, single feed, and have a capacity of five rounds of .338 Lapua.
The two-stage trigger pack is easily removable from the rifle. It can be adjusted from two to four pounds at the second stage, and can also be tuned for take-up, length of pull, and position. The safety is mounted inside the trigger guard like an M1 Garand safety.
Sako provides accessories for the TRG-42 including an adjustable butt pad, hard-case, slings, "Optilock" quick-detach and tactical scope mounts, muzzle brake, bipod, target-style iron sights, and 1913 Picatinny rail.
