A short introduction to the process for the control testing of selected weapons made by CZUB
The aim of the control tests was to fully verify and to objectively assess the technical capabilities and the level of compliance, i.e. the achievement of the technical parameters required and the standards of the goods (the weapons and their accessories). In other words, by testing to verify in practice the selected technical parameters and characteristics defined by the technical regulations that were incorporated into the test methodology.
The tests carried out in an accredited testing laboratory for weapons.
In this actual series of tests the following weapons were sequentially deployed: the CZ 75 SP-01 Phantom, the PDW CZ Scorpion EVO 3 A1, the CZ 805 BREN - in two versions (CZ 805 BREN A1,CZ 805 BREN A2), and additionally the CZ 805 G1 and CZ 750 S1M1 suspended grenade launchers. All these products were equipped with their extensive accessories.
CZ 75 SP-01 Phantom pistol - 6 weapons and their accessories were tested in 14 precisely defined tests.
Test of target grouping and accuracy
Carried out by two shooters (one from CZUB), using a solid support, at a distance of 25 m, whereby each of the shooters made 3 sightings of the target firing 5 rounds from each of the 6 weapons avoiding any possibility of repeated sighting or of a missed shot being repeated. All 5 hits were required to be in the target, within a circular diameter of 118 mm. Each shooter was required to make 18 consecutive error-free sightings, i.e. 90 accurate hits. This test was extremely demanding especially in terms of the psyche and the concentration of the shooters. A respectable performance by the nominated shooters.
Test of the durability and the safety of the weapon when dropped - tested using one gun
Parameters of the gun drop test – a drop height of 1.5 m; dropping always carried out in a triple-series: on the right side, on the left side, on the chase, onto the lower part of grip, onto the upper part of the body (the sights), onto the rear part of the body (the trigger). Dropping onto the trigger was carried out in all the positions of the striking mechanism, i.e. the trigger set at the safety notch, cocked in the rear position, with the trigger in the forward position set on the firing pin. In total this represented a respectable 54 drops. Between the various drop positions and following the completion of this series, the gun was required to flawlessly shoot a full magazine.
Subsequently tested independently was a magazine loaded with live ammunition which had undergone free falls from the height of 1.5 m, always three falls in each position: on the left side of the magazine, the right side of the magazine, the bottom of the magazine and the mouth of the magazine. And again tested by firing. Rating requirement: Nothing may fall off or break off the weapon (the magazine) and it must shoot reliably.
Result - complied.
The statement: "... meets the specified parameters" was made in all the other cases for a total of 14 tests.
PDW CZ Scorpion EVO 3 A1 - Testing of 6 weapons with their accessories by 16 tests.
Examination of the distance of the effective firing range - tested on two weapons
- mechanical sights (front sight, rear sight) - 100 m, supported laying position, three 10-round sightings with single shots, the target – a figure running forward; requirement for achieving compliance – minimum 50% of target hits, i.e. at least 15. Reality: 30 hits each time.
- utilising the MEPRO 21 collimator - 200 m, under the same conditions as above. Reality: 21 and 22 hits.
Test of shooting at a low temperature of -40°C – tested on 3 weapons
Testing process – the weapons were tempered at a temperature of -40°C for 2 hours, then tested by firing 90 shots from each weapon, then re-frozen at -40°C (40 minutes). After tempering had been carried out in this manner, both the gun and ammunition were transferred from the freezing chamber into a chamber with a temperature of (+20 ÷ +25°C) and relative humidity of 70% until the weapons and ammunition became damp. The weapon and the ammunition, with condensation on them, were again deposited in the chamber and tempered at -40°C for 1 hour (ice-accretion). This was followed by test-firing 90 shots from each weapon.
Result - no defects.
Also successfully tested was the CZ 805 BREN A1 in both its variants, including the suspended grenade launcher.
CZ 805 BREN A1, A2, CZ 805 G1 - tested were 7 BREN long rifles, 3 carbines and three grenade launchers in a total of 19 tests.
Test of target grouping and accuracy - tested on 6 weapons
The testing took place over 2 days and also part of the shooting was carried out at night, so the shooters were fully active during the first day from 8 a.m. to 1 a.m. of the next day and again in the morning from 6 a.m. to 9 p.m.
Testing of target grouping and accuracy using assault rifles was carried out from a distance of 100 m using mechanical sights, with the rifle separately and then in combination with a suspended grenade launcher mounted, individual shots in pairs. Supported laying position of the shooter, sighting with 10 rounds; each shooter carrying out 1 sighting. Additionally, in combination with the collimator sight of the ZD-Dot type, the DV-MAG3 day telescope accessory + the ZD-Dot collimator sight and the NV-MAG3 night telescope accessory + the ZD-Dot collimator sight. In total each shooter made 30 sightings with 10 rounds with a scatter of up to 116 mm.
Testing of target grouping and accuracy of the suspended grenade launcher was conducted from a distance of 100 m using mechanical sights, with single shots and by one shooter. Unsupported standing position of the shooter, sighting 5 rounds; during this test the grenade launcher was mounted on a CZ 805 BREN A1. All five shots were concentrated in a rectangle of 23 x 87 cm.
Testing of the distance of the effective firing range of the CZ 805 BREN and the CZ 805 G – with mechanical sights
Assault rifles - the CZ 805 BREN A1 (long) at a distance of 500 m, the CZ 805 BREN A2 (carbine) at a distance of 400 m. Target "a figure running forward", three 10-round sightings, supported laying position of the shooter. 19 hits out of 30 in the target in the case of the long rifle and 16 hits out of 30 for the carbine.
The CZ 805 G1 light rifle-mounted grenade launcher at a distance of 150 metres (point target - the target with dimensions of 2.4 x 2.4 m) Result: 5 hits out of 6 in the target.
At a distance of 350 metres (square target - a rectangle with a width of 10 m and a height of 20 m). Result: 4 hits out of 6 in the target.
CZ 750 S1M1
The most effective tests of this weapon included the verification of the target grouping and accuracy, which was tested at 500 m with a day optical sight, a night sight and a thermovision sight always by two 5-round sightings up to a scatter of 150 mm. How else other than satisfactory.
