Japanese Arisaka Model Mm Carbine

By Edward J. Hoffschmidt

Few guns have been as maligned as the Japanese Model 1905 (Type 38) cal. 6.5 mm. rifle. During the early stages of World War II, ill-informed observers were calling the gun a piece of junk. The 6.5 mm. cartridge was considered totally inadequate for military use. Few correspondents took the time to find out how good the gun and cartridge really were.

The Arisaka is basically a modified Mauser. It was developed under the supervision of Col. Nariaki Arisaka, Superintendent of Tokyo Arsenal, and officially designated as the Type 38 (1905). Since the rifle is basically a Mauser, it has inherent safety features. The Arisaka is designed to handle gases from a ruptured case or primer. There are 2 gas escape holes in the top of the receiver and a large combination safety catch and gas shield to divert gases and brass particles away from the shooter's face. The bolt has large, solid, front locking lugs and the bolt handle engages a cut in the receiver and thus acts as a third or safety lug. The bolt has another lug about Vx" behind the left front locking lug which performs a number of jobs. It serves as a guide rib to prevent the bolt from jamming when the locking lugs pass through the section of the receiver cut away for clip loading. It also acts as a bolt stop. Its most important function is to cam the ejector into the path of the bolt. Unlike most Mausers, the ejector is not spring-operated, but rather it pivots on a separate screw; when the bolt is opened and pulled back, the bolt lug strikes the rear of the ejector, camming it into the bolt cut in the receiver.

The stock construction is unusual. The butt is made in 2 pieces dovetailed together. This method allows the use of smaller blanks and a stronger grain direction through the pistol grip area. The 2 steel tangs extending back from the action strengthen the pistol grip area even more.

Although the Japanese cal. 6.5 mm. Arisaka rifle is an excellent military arm, it has a number of faults from

36. Cleaning rod the American point of view. First, the action cocks on closing, which, however, with practice becomes no more trouble than a cock-on-opening action. Some find the safety catch awkward and the trigger pull is generally poor.

The cal. 6.5 mm. Arisaka was made in a variety of sizes and models, ranging from the carbine to the long rifle. Early cal. 6.5 mm. rifles were as finely

ITo remove assembled bolt (6), first pull it all the way to rear. Then pull bolt stop (8) out to clear stop lug on bolt. Unlike other Mauser rifles, it is not necessary to engage safety in order to disassemble bolt outside receiver

2 To disassemble bolt, hold it as shown and push safety catch (1) in as far as it can go. Rotate bolt Va-turn and ease out safety catch, firing pin (3), and firing pin spring (2). When reassembling, sear notch must be seated in shallower notch in bolt so that firing pin does not protrude.

Then push in safety catch

3 Extractor (5) is attached to bolt in typical Mauser style. To remove it, rotate extractor until small guide rib which rides in groove in front end of bolt is free of groove. Push extractor forward until it snaps free of extractor collar finished as the average sporter.

Shortly before the beginning of World War II, the cal. 6.5 mm. rifle was superseded by the Type 99 (1939) cal. 7.7 mm. rifle.

While the Type 99 has basically the same action as the Type 38, the design was simplified and the majority of parts are not interchangeable with those of the Type 38 rifle.

4 To empty magazine without running cartridges through gun, release floor-plate (25) by depressing floorplate release (26) in as far as it will go. Floorplate, magazine spring (20), and follower (19) are now detached from magazine

5 To remove bolt stop screw (9), action must be removed from stock. To remove bolt stop spring (7), rotate it 90° as shown and pull it free of bolt stop (8)

6 All Japanese cal. 6.5 mm. rifles are equipped with a full-length cleaning rod for threading to a handle in the soldier's cleaning kit. To remove cleaning rod (36), push in on long spring that retains front band (35). To remove band (35), remove rod and depress spring as far as possible, and then gently drive off front band ■
