The complete Slavia APP 661 package

Comments:  The Slavia APP 661 is a very well built air pistol that operates in true semi-auto mode. Each time the gun is fired, some gas is used to re-cock the gun. Seven shots can be fired in rapid succession from the spring-fed magazine. While both steel and lead BBs can be used, the owner's manual recommends lead BBs for maximum accuracy. It was made in Czechoslovakia (now the Czech Republic) in the mid to late 1960's. I'm not certain when production stopped. The early version of the APP 661 used 8 g CO2 cartridges only. The later version came with interchangeable adaptors to use either 8 g or 12 g CO2 cartridges (click here for more information on versions). The specimen shown here is the later version. While the gun itself is not exceptionally rare, finding one in the box with papers is difficult. While this gun is not very powerful, it is quite accurate for a BB gun and is fun to shoot at short distances. This particular specimen shoots as good today as it did 40 years ago from the factory.

Performance: The target shown below is the original factory test target shot on March 31, 1967.

Measurements were made on 11/05/07 at a temperature of 71 F and 14' elevation. A ten shot string was fired from a bench rest at 15' using Gamo Round lead balls (8.0 gr). The highest velocity measured was 178 fps, the lowest was 149 fps (average of the 10-shot string was 161 fps). A six shot string fired with open sights grouped at 0.68".

Right Profile: The rear sight is adjustable for windage using the opposing screws on each side of the rear sight. Loosen one screw and tighten the other to move the sight left or right.
Front View: The front sight is adjustable for elevation by turning the screw at the front of the sight.
Right Side Markings:
Left Side Markings: Rotating the safety lever to the right cocks the gun and engages the safety. Rotate the lever to the left to fire the pistol. Once the gun has been fired, it recocks itself using some of the gas from the previous shot.
Top & Bottom Markings:
Loading BBs: Pressing the buttom just behind the trigger releases the BB magazine. The spring follower is pulled down and seven steel or lead BBs are loaded through the hole on the side.

Re-inserting the magazine is made easier by pressing the release button while inserting the magazine.

Loading CO2: This airgun can use either 8 g or 12 g CO2 cylinders, depending on which piercing assembly has been installed. The cylinder is inserted, neck up, and the cap is screwed on and tightened until the cylinder is punctured. The cap is then backed off about 1/5 turn. Due to the design of the seals around the piercing pin, cylinders that do not have a seam on the side work best (e.g. Daisy, FirePower, Gamo -- not Crosman).

Packaging: This specimen of the APP 661 includes all of the original packaging, including the test target shot at the factory and the tool for inserting/removing the piercing assemblies. It also includes the owner's manual (written in German) and an English translation along with both the 8 g and 12 g adaptors.
