Specprom SAPI Extra Large Armor Plate Set, 285x355 mm (5005Armox)

Brand: Specprom. Category: Military Gear > Armor Plates. This armor plate set is designed for those who value a combination of maximum protection, anatomical comfort, and acceptable weight.

Key Features at a Glance

The SAPI Extra Large model is presented in a size of 285 x 355 mm (original SAPI size grid) with a weight of approximately 4.2 kg. The technical description also states that the actual dimensions of the armor plate may be 285 x 360 mm with an anatomical curve across the width, conforming to the shape of the chest. The nominal thickness of the armor steel in the plate is — 5 mm, and the full plate coating gives a total product thickness of 21 mm.

Materials and Construction

The plate is made of Armox Advance armor steel from the Swedish SSAB concern, with a hardness value of 58–63 HRC. To enhance anti-fragmentation properties, Ukrainian-made ballistic felt, laminated with PVC film for moisture protection, is used. The felt is cut to the precise dimensions of the plate and pressed for several hours to ensure reliable adhesion to the metal core; additionally, side edging made of material with a density of 800 kgm³ is applied, which is pressed in a special device for an hour and a half to minimize lateral core ejection upon impact.

Behind the armor plate, an 8 mm thick EVA damper with a density of 80 kgm³ is installed, providing durable mitigation of blunt trauma and better deformation reduction performance compared to standard expanded polyethylene dampers with a density of 30–35 kgm³.

Ballistic Characteristics and Certification

The plate is designed as a SAPI (Small Arms Protective Inserts) type, used in the US Army, and meets the requirements of DSTU 8782:2018 for Class 4 protection. According to laboratory test results, the product demonstrates increased resistance: it withstands at least one shot from an AKM 7.62×39 rifle with a 57-BZ-231 (armor-piercing incendiary) bullet.

According to DSTU Class 4 protection criteria, the plate withstands: SVD rifle, 7.62-mm 57-N-323s (LPS) cartridge with a bullet velocity of 850±15 m/s; AK-74 rifle, 5.45 mm cartridge, 7N10s bullet with a velocity of 910±15 m/s. Additionally, it is noted to withstand AKM 7.62×39 with 57-BZ-231 bullets and AK-74 with 7N6M bullets. Note: since 1989, the LPS cartridge was replaced by a cartridge with an ST-M2 bullet (core hardness 65 HRC), which is an analogue of the B-32 bullet for Class 6 protection.

Each armor plate has a unique serial number and production date. Batches of plates undergo testing in a certified laboratory, after which a certificate and test report are issued; the certificate is valid for 6 months from the date of issue. Documents can be viewed on each product page.

Size Chart and Fit

The SAPI system is presented in five sizes; for this XL (Extra Large) model, the parameters are: 285 x 355 mm. Recommended correspondences: for men with a chest circumference of 123–132 cm; for women — suitable when the distance between nipples is 266–285 mm. The cut corners of the plate do not restrict movement and ensure comfortable use of firearms.

Advantages of Armor Steel Compared to Ceramics

• Armor steel plates withstand multiple shots, while ceramic plates are usually single-use and require immediate replacement after impact.
• Blunt trauma deformation of armor steel is significantly less, which reduces the risk of rib fractures or internal organ damage compared to ceramic plates in the absence of a ballistic vest.
• Armor steel plates distribute bullet energy across the entire surface, rather than point-wise, which improves injury reduction performance.

This armor plate set is an optimal choice for those seeking reliable protection combined with anatomical comfort and durability. Manufacturer: Specprom. Purpose: military and tactical use, suitable for defenders.
