At my request management firm
shared with me the results of tests of their products.
We tested the DCT-1 ...
- DTK-2 ...
The results of measurements of the sound.
The measurements were made at a distance of 0.2 meters on the left hand ear.
Regular DTK AK74 - 162.62 dB
DTK-1 - 169.96 dB
DCT-2 - 170.02 dB
DCT-3 - 168.99 dB
DCT-4 - 141.3 dB
The result of measuring the average energy of the recoil when firing:
AK-74 without a muzzle brake - 2.94 J
AK-74 with the standard DCT - 1.86 J (efficiency 38% DTC)
AK-74 with the DCT-1 - 1.39 J (DTK-effectiveness of 55%)
AK-74 with the DCT-3 - 1.2 J (efficiency -59% DTC)
AK-74 with the DCT-2 - 1.39 J (DTK efficiency - 55%)
AK-74 with the DCT-4 - 1.68 J (efficiency DTK 43%)
Changing the angle of deflection:
AK-74 without a muzzle brake - 3 degrees 10 minutes
AK-74 with the standard DTK - 2 degrees 30 minutes
AK-74 with the DCT-1 - 2 degrees 10 minutes
AK-74 with the DCT-3 - 2 degrees
AK-74 with the DCT-2 - 2 degrees 10 minutes
AK-74 with the DCT-4 - 2 degrees 25 minutes
The shooting was done from an AK-74 cartridge 7N6. Tests were conducted on five shots with each DTC.
Repeated tests for DCT-4 with modifications.
The result of measuring the sound level at a distance of 0.2 meters from the left ear, hand:
AK-74 with the standard DCT - 162.62 dB
AK-74 with the DCT-4 (7.62 mm) - 136 dB
AK-74 with the DCT-4 (5.45 mm) - 132.3 dB
Changing the grouping, cm (scattering):
Series of 20 shots at a distance of 100 meters of single shots in the standing position.
AK-74 with the standard DCT - 19h25
AK-74 with the DCT-1 - 17h24
AK-74 DCT-3 - 16h13
AK-74 DTK-2 - 14h20
AK-74 with DCT-4 (5.45) - 12x8
AK-74 with DCT-4 (7.62) - 9x5
(Results on the accuracy of subjective, as is very dependent on the arrow)
