Tikka M65


The Tikka M65 is a Finnish rifle designed by a Finnish firearms company Tikkakoski in 1969. It was designed as a long action rifle on the basis of the short action Tikka M55 rifle, however its action differs much from the M55. Like the Tikka M55, the M65 was imported to the United States by Ithaca Gun Company.

History

company had designed the Tikka M55 in 1967–1968 and it had been brought to production in 1968. However, it could only use cartridges with cases up to 55 mm, and Tikkakoski decided to develop a long action rifle in 1969, the M65, which initially was called LSA65, for cases up to 65 mm long. In 1972 the rifle was renamed to M65.
Tikkakoski company was bought by Nokia in 1974 and by Sako in 1983. Sako also bought Valmet in 1986. After the success of the Tikka M55 as a sniper rifle, in 1988 Sako brought a purpose-built sniper rifle Tikka M65A to the market, with significant modifications to the basic design. The M65A took some design features from the Valmet Sniper M86, such as the aluminium bedding block.
In 1987 the Tikkakoski factory was run down, all its machinery was destroyed, and production of Tikka rifles was transferred to Sako factory at Riihimäki. The last Tikka M55 and M65 were assembled in 1989. In 1990 the Tikka M65 was superseded by the Tikka M658 rifle of the Tikka M88 series.
The design work from the Tikka M65A and Valmet Sniper M86 were used to develop the Sako TRG sniper rifle in the early 1990s.

Design

The Tikka M65 action is based on the Tikka M55, which in turn is loosely based on the Mauser action, which Tikkakoski had wanted to modernise. The repeating magazine fed rifle features a milled receiver made from special steel, to which a 90° rotating, two-lug cylindrical bolt locks; the M65 also incorporates two additional safety lugs at the rear of the bolt, as well as two vent holes in the bolt body to vent off gases to the side if a primer breaks. Unlike the M55, the M65 also features an integral recoil lug, which is made to the receiver in the milling process. The receiver has 17 mm dovetail rails milled on its top side for attaching optical sights as in the M55. The later model bolts have a large handle with a plastic ball-shaped end. The M65A also has a polyacrylamide bushing as a bolt guide.
The barrel is cut rifled with 6 grooves and depending on the model, either 520 mm, 560 mm, 620 mm or 660 mm long. Just as in the M55, some models feature iron sights attached to the barrel; rear sight is an open notch and front sight is a hooded post. The barrel is free-floating, also in the Fullstock variant.
The trigger mechanism has an adjustable trigger pull between 0.8–1 kg and 3 kg. The trigger pull can be adjusted by rotating a screw inside the magazine well. The trigger has a tendency to produce unintentional discharges if the trigger pull is set too light.
In the standard versions, the magazine is either a 4, 5, 7, 8 or 10-round double stack stamped steel magazine, and the magazine catch is located in front of the trigger, within the trigger guard. In M65A, the magazine is either a 5 or 10-round single stack single feed stamped steel magazine, and the magazine catches are attached to both sides of the magazine itself, as in the Valmet Sniper M86.
The sporter variants feature heavy walnut stocks which are convex towards the cheek and concave on the away side, and have UIT rails on their underside and left side, for attaching different accessories. The M65A has an aluminium bedded stock with an aluminium chassis inside the walnut stock like the Valmet Sniper M86. The butt of the M65A rifle is attached to the chassis with an aluminium tube, and it has a fully adjustable walnut cheekpiece; the front end fo the stock is made with two walnut stocksides, which attach to the aluminium chassis. At the underside of the M65A there is an UIT accessory rail for bipods and such accessories.
