Ballistic insert K5A "Chrabąszcz"
The K5A ballistic insert (PN-V-87000:2011 equivalent to NIJ 0101.06 Level IV) has been designed as a stand-alone protective plate, providing effective protection against fragments and 7.62×51 mm ammunition (AP ammunition) with an initial velocity of 820 m/s ± 15 m/s.
K5A ‘Chrabąszcz’ ballistic plates have been tested in the accredited WITU Small Arms and Protective Shields Testing Laboratory (PCA No. AB 171). Four separate ballistic tests were conducted, each on two independent plates (in dry conditions, rain, temperature +50℃, temperature -40℃).
The plate is lightweight and ergonomically designed, allowing for comfortable wear without restricting movement. The plate was additionally tested at ISL (French-German Research Institute Of Saint-Louis) using 30.06 AP M2 ammunition, which corresponds to NIJ 0101.06 Level IV.
Each batch of 300 pieces undergoes ballistic testing in accordance with the requirements of the Polish Army. The plate, after FULL ballistic testing, is intended for the civilian market - no permit/licence is required.

Reliability Guarantee: K2 “Biegacz” Ballistic Testing Process
From rigorous laboratory tests to extreme climatic conditions — find out how the “Chrabąszcz” cartridge passed certification according to the Polish standard MON-V- 87000:2011.
Quality that protects life
Our covers K2 “Biegacz” with Successfully passed all the tests, meeting the criteria standards PN-V- 87000:2011 and demonstrating a high level of reliability even under extreme conditions of use. Plate deflection was located in the compartment 26—31 mm, which remains below the permissible limit of 45 mm specified in the current standard.
This kind of comprehensive examination is crucial for us — not only as a formal requirement, but as proof of the quality and durability of a product that can decide human life in real conditions.

Learn the detailed process of verifying the ballistic parameters of the “Runner” model. From strict legal requirements, to climate tests, to an independent expert assessment of each shot.
Compliance with Standard PN-V- 87000:2011
Before our product reaches the market, it must undergo rigorous ballistic tests, in accordance with the requirements of the Polish standard MON-V- 87000:2011. This standard specifies the test procedures for ballistic shields, classifying them according to their level of protection, and describes in detail the conditions that must be met during testing in order for the results to be reliable and comparable. These tests shall include ballistic resistance tests on a randomly selected group of shields from a given production batch.
Climate and Humidity Testing
Plates K2 “Biegacz” passed 4 series of rigorous trials in an accredited Laboratory of Research of Small Arms and Security Guards WITU. Each test was carried out on independent sets of plates under the conditions of:
Dry conditions — reference samples.
Irrigation simulation — assessment of the effect of moisture on the composite.
Heat up (+50°C) — Imitation of a hot climate.
Cool down (-40°C) — mapping Arctic conditions.
Impact Parameter Control
Each of the tests included 6 shots in precisely defined places on the board, according to the arrangement indicated in the standard, which allows to evaluate both the point resistance and the structural behavior of the shield after repeated firing. The key parameter was the preservation of a strictly defined projectile speed — in the case of the K2 class: 420 ± 15 m/s — with a shot distance of exactly 5 meters.
Methodology and Expert Supervision
A total of 48 shots (7.62x25mm P-shell ammunition) were fired during the tests under controlled test conditions. Each trial was evaluated independently by 2 experts conducting research. The evaluation took into account measurements of the velocity of the projectile and the subsurface depression under the cover formed as a result of the deformation of the plate.
