Arsenal Patriota SAPI Large Armor Plate BZ 260x340 mm (40083Armox) — Specprom

The Arsenal Patriota SAPI Large Armor Plate BZ 260x340 mm (40083Armox) from Specprom is a high-quality protective plate from the Military Gear > Armor Plates category, designed for reliable, multi-hit protection against small arms in accordance with Class 4 of DSTU 8782:2018. The plate weighs 3.7 kg and offers an optimal balance of weight, thickness, and ballistic resistance for active use in combat and civilian conditions.

Purpose and Design Features

The SAPI (Small Arms Protective Inserts) design is adapted for a wide range of users: from military personnel to civilians. The L (Large) version measures 260 x 340 mm, with a 265 x 340 mm variant also mentioned; the plate's shape includes an anatomical curve across its width to conform to the chest contours, and cut corners do not restrict movement. The sizing is suitable for men with a chest circumference of 113–122 cm and for women with a nipple distance of 246–265 mm.

Materials and Manufacturing Technology

The plate's core is made of Swedish SSAB armored steel (Armox Advance brand) with a hardness of 58–63 HRC and a nominal metal thickness of 5 mm. The front is covered with Ukrainian-made ballistic felt, laminated with a PVC layer for moisture protection; the felt is precisely cut and pressed using a multi-stage method, ensuring reliable adhesion to the metal and preservation of the coating after multiple impacts. The side edging is made of material with a density of 800 kg/m³ and is pressed together with the plate, which reduces the likelihood of core deflection when the plate's edge is struck.

An 8 mm thick EVA damper with a density of 80 kg/m³ is installed behind the plate. Unlike standard dampers with a density of 30–35 kg/m³, this damper hardly deforms over time and more effectively reduces backface deformation, minimizing the negative impact from rifle and sniper round hits.

Thickness, Weight, and Dimensions

The total thickness of the plate with full coverage is 21 mm; the metal layer is 5 mm. Dimensions: 260 x 340 mm (L), with 265 x 340 mm also mentioned in the text. The product weight is 3.7 kg. The anatomical curve across the width and cut corners ensure comfort and freedom of movement.

Certification and Documents

Each armor plate has a unique batch number and production date. Batches undergo testing in a certified laboratory for compliance with DSTU 8782:2018 under normal conditions. Based on the test results, a batch certificate valid for 6 months from the issue date and a test protocol are issued; documents are available for review on the product page.

Ballistic Characteristics (according to DSTU)

• SVD rifle — 7.62-mm cartridge 57-N-323s (LPS) or similar — bullet velocity 850±15 m/s.
• AK-74 assault rifle — 5.45 mm cartridge, 7N10s (PP) bullet — bullet velocity 910±15 m/s.
• Note: since 1989, the LPS cartridge has been replaced by a cartridge with an ST-M2 bullet with a core hardness of ~65 HRC (analogous to the B-32 bullet of Class 6).
• Additionally, the plate withstands AKM 7.62x39 with 57-BZ-231 (armor-piercing incendiary) bullet and AK-74 cartridge with 7N6M bullet under appropriate test conditions.

Advantages of Armored Steel over Ceramics

Armored steel provides multi-hit protection and less need for immediate replacement after impact, unlike ceramic plates, which are typically single-use. Armored steel distributes bullet energy over a larger area, reducing the risk of rib fractures and internal injuries; backface deformation is also lower when using a quality damper, which helps reduce traumatic consequences for the user.

Who It's For

This armor plate is suitable for military formations, law enforcement agencies, security structures, and civilian users who require reliable, multi-hit protection with well-documented certificates and test protocols.
