and to lower cost without interfering with the accuracy or performance of the regular M1903A1.

One major difference between this rifle and the earlier design is the use of a new receiver rear sight.

A longer handguard (called a barrel guard) covers the area occupied by the old leaf sight oi the early models.

Pistol grip is optional in this design. While very early Model 1903A3 rifles had stock screw pins passing laterally through the center of the stock to reinforce triggerguard and magazine well, late models have stock screws and nuts similar to the M1903.

The upper band assembly, lower band and its swivel, and triggerguard magazine assemblies are all stampings. Triggerguard and magazine units are staked and welded. The extractor collar is also stamped.

Buttplate group is the same as the M1903A1 except that it is made of stampings. and buttplate cap is not easily removed. Butt swivel groups consist of two plates with the swivel between welded together and fastened with two butt swivel screws.

Front sight groups consists of a flat front sight pinned into a slot in a ring-type sight base. The base is keyed and pinned to the muzzle; 5 heights of sight are provided, varying from .477 to .537 inch.

Rear sight is a receiver type mounted on the rear of the receiver bridge. It lias a dovetailed base, a windage yoke with range scale graduated in 100 yard divisions and with 50 yard adjustments. The slide aperture can be raised or lowered from 200 to 800 yards. A windage knob moves the yoke to either side in clicks which represent a shift of one minute of angle. This represents a shift in the point of impact of one inch for each 100 yards of range involved.

The magazine follower is a sheet steel stamping. A straight ridge extends longitudinally on its top side. The front end is narrower than the rear and a section there is bent down and in on both sides to retain the magazine spring. A projection at the rear end holds the spring in position (although the 1903 follower is a machined piece, the stamped groups just described are interchangeable with it).

Some of the bolt parts of the 1903A3 are differently made than those of the

1903. In Oct. 1942 two groove barrels were approved for the 1903A3. There were 945,856 M1903A3 rifles produced by Remington and L. C. Smith Corona.

ceiver itself). No metallic sights are used 011 this rifle. Stock has a full pistol grip and notch for the bolt handle which is altered in shape as required by telescope mounted above. Bolt handle curves downward and is cut away on outside to provide clearance for the telescope as the boll handle is raised. Since the telescope blocks the clip guides in the receiver bridge, this rifle can be loaded only with single cartridges. No bayonet mounting is provided. The Weaver 330C is the common telescope sight employed. This 2.5 power telescope can be elevated to 1200 yards and was called M73B1 in the Government Service.
