CZ SCORPION EVO 3 submachine guns and carbines
What does the EVO 3 mean? This somewhat mysterious part of the CZ SCORPION EVO 3 A1/S1 name expresses the fact that from the manu facturer’s point of view it is already the third generation of the modern automatic weapons for the pistol ammunition. The submachine guns were produced in the Česká zbrojovka Uherský Brod already soon after the Second World War and especially the ingenious model line of Sa 23/25 and Sa 24/26 enjoyed in its time quite a respect and admiration; nowadays the Company shows with pride its revolutionary vz. 61 Škorpion submachine gun. This original weapon occupies the borderline between pistols and submachine guns and is considered
the bolt. This solution brings the advantage of a charging handle remaining stationary during firing, avoiding any risk of collision with shooter’s hand or other obstacles. After firing the last round the bolt remains to the rear, with the release button on the left side of the trigger container. The bolt could be released forward also by a short pull back on the charging handle. The heart of the new Scorpion’s design and the key to its success is the sliding
attachment of the bolt on the removable trigger block and using a central rod with a single return spring as a guide to the bolt. This simplest, but in the end a truly brilliant idea (protected by international patents, indeed)
Scorpions do not have slightest problems with desert environment and operate safely with all variants of the 9x19 rounds regardless of the manufacturer and bullet shape.
allowed to simplify radically the complete design of the weapon and of course also its manufacture. It can be seen especially on the bolt as the stresses imposed on it are minimal, it could be designed as a simple two‑part shell of a strong structural polymer. A bonus for the user is the extremely sim ple and rapid disassembly: The complete bolt assembly with the return spring is re moved from the bolt casing from below after removal of the trigger container, the whole sequence commences with
to be the first generation of Škorpions or Scorpions, respectively, as in the nineteen ‑nineties the Česká zbrojovka modified the name to the ‘international’ spelling of SCORPION and registered it as its trademark. The second generation of the Scorpions represents the model CZ SCORPION 9x19, put to market in late 2003 in small series only. The contem porary Scorpions are from the design and /material point of view way different. However, the end users apparently do not object at all to this declaration of conti nuity of an illustrious tradition. No, they feel rather the opposite, as the famous name gives a guarantee of technical ingenuity and high quality of manufacture.
just removal (sliding out) of one pin at the front of the container; the trigger container is then unhooked from the rear hinge. It takes a few seconds, the number of parts removed is minimal and of course no tools at all are necessary. The structural polymer is used also for moulding of the forestock (a separate part slid over the barrel), for the trigger container, the pistol grip and for the folding telescopic (length‑adjustable) stock. The result is a pleasantly low total weight of the weapon (without ammunition it tips scales at way below three kilograms/6.6 lbs) and touch comfort. Also worth mention ing is the ample accessory space on the Mil‑Std-1913 (Picatinny) rail, occupying the whole top of the submachine gun and flanking the three sides of the forestock. Excellent human engineering If there is something the submachine guns and carbines CZ SCORPION EVO 3 also excel in, it is their lovingly tuned ergonomics – the human engineering. This era of modern structural polymers and 3D modelling al lows you to create miracles with the final product shaping and the designers took full advantage of that. Their consultations with members of the élite military and security forces were an immense boon for their work. Thanks to that the new Scorpions fit in hand like a glove for most anyone, this fact helped also by the ability to adjust the pistol grip horizontally to suit individual preferences and body proportions. The users are also unanimous in their praise of positioning the controls exactly where the shooter would intuitively seek The best of CZ |
