MP34

The Steyr-Solothurn MP34 (maschinenpistole 34 or machine pistol 34) is a submachine gun that was developed secretly by Rheinmetall during the manufacturing restrictions imposed on Germany by the 1919 Treaty of Versailles. This was accomplished by acquiring the Swiss concern Waffenfabrik Solothurn where the prototype was developed. Once the prototype was ready, Solothurn did not have the ability to mass produce it. Rheinmetall then acquired a controlling interest in the Austrian concern Waffenfabrik Steyr, where the gun was mass produced.1

During automatic fire, the MP34 will fire 600 rounds per minute. 2

This gun is known by some as the Rolls-Royce of submachine guns due to the quality of the build.3

gunsmithing note(s):

      • The safety locks the bolt forward.4
      • Push in the spring loaded bolt cap to open the top cover.5
      • This gun has a side mounted 32 round magazine.6
      • The magazine can be inserted into the magazine mount from the bottom to be able to load it with stripper clips.7
      • There is a bayonet lug on the right side of the weapon.8
      • This gun has a semiautomatic and automatic fire selector switch.9

TAVOR SAR

The Israel Weapon Industries (IWI) Ltd. TAVOR SAR is a semi-automatic bullpup rifle available in a variety of calibers and configurations.

gunsmithing note(s):

      • The barrel lock pivot assembly can be removed from the body/receiver using the following steps:1
        1. The barrel will need to have already been removed.
        2. On the right side of the gun rotate the white line on the barrel lock pivot assembly to the twelve (12) o’clock position.
        3. Push the barrel lock pivot assembly through the body/receiver from right to left. If you meet resistance do not force it. Just jiggle the barrel lock pivot assembly by rotating it clockwise or counterclockwise slightly until the resistance is eliminated.NOTE: Once the barrel lock pivot assembly is out of the body/receiver you will see two pins that extend from the bottom of the assembly. In step one, we align the white line with the twelve o’clock position to align these pins with the cutout on the bottom of the barrel lock pivot assembly hole on the left side of the gun.
      • Do not lock or unlock the barrel lock pivot assembly while the cocking bar is installed in the gun. The barrel lock pivot assembly will crush the cocking bar and bend it requiring replacement. 2

74

The Winchester Model 74 is a rimfire rifle that is fed by a through the buttstock tubular magazine.

gunsmithing note(s):

      • The <em>Operating Slide<em> is a commonly broken part. No obsolete parts dealer that I know of has any.

760

The Remington Model 760 GameMaster is a pump action centerfire rifle that is fed by a four round box magazine. The gun was designed by L. R. Crittendon and William Gail Jr. and was introduced in 1952.1

gunsmithing note(s):

      • The original Remington Model 760 magazines were made of a single deep-drawn sheet of steel. This made the box and the floor plate all out of the same piece of metal.2
      • Later versions of the Remington Model 760 magazines were made by a different company and they had a metal box but a plastic floorplate. These are known as new style magazines. In older guns, these magazines can need to be fit for smooth movement in and out as well as locking.3
      • The Remington Model 740 series magazines and the Remington Model 760 series magazines were all made on the same tooling so they should interchange.4

A303

The Beretta Model A303 is a semiautomatic shotgun that is fed by a tubular magazine.

gunsmithing note(s):

      • A303 barrels made prior to 1994 are soft soldered. A303 barrels made in 1994 and after are silver soldered.1
