Indoor ranges demand an envelope that protects shooters, instructors and facility staff while surviving continuous live fire. ArmorBlock delivers a structural and ballistic solution that outperforms legacy precast, steel-lined walls and SACON products. It gives designers a dependable way to build safe, quiet and durable ISAR facilities that last.
Amidon ArmorBlock is a purpose-built ballistic concrete block engineered from the ground up for live-fire interiors. Each block carries the mass, density and toughness needed to stop and contain high-velocity rounds. Shot-to-shot performance is consistent, even in high-volume training environments. Walls stay intact. Maintenance stays low. Safety margins stay high.
ArmorBlock solves the most common problems that architects and range integrators face in ISAR projects.
Impact Resistance.
The ArmorBlock matrix absorbs and dissipates energy from repeated small-arms fire. It eliminates the spalling and unpredictable fragmentation seen in conventional concrete and reduces dependence on costly steel liners.
Predictable Ballistics.
Every block is produced to meet strict density and compressive strength targets. That consistency gives the design team clear calculations for setback, stand-off and containment.
Quiet and Controlled Environment.
ArmorBlock offers high inherent mass which improves sound control and reduces vibration throughout the structure. This creates a better experience for shooters and a more manageable environment for instructors.
Simplified Construction.
ArmorBlock installs like standard CMU. No special forming. No multi-stage steel fabrication. This keeps ISAR construction schedules tight and cost exposure low.
Higher Lifespan.
Legacy solutions often depend on sacrificial surfaces that require regular replacement. ArmorBlock withstands heavy use without constant rebuilds, which cuts long-term operating costs.
Architectural layouts built with ArmorBlock rely on a reinforced ballistic envelope that forms:
• Sidewall ballistic containment
• Backstop and tapered impact zones
• Protected mechanical and electrical chases
• Durable control room partitions
• Shooter stalls and separation walls
Each detail benefits from ArmorBlock’s density, strength and buildability. Line-of-fire elements are created as true structural walls rather than thin protective layers added after the fact. Designers gain more freedom to optimize geometry for airflow, safety, and range rules.
If desired, Amidon can provide conceptual layouts showing typical ArmorBlock wall sections, example stall configurations and the recommended way to form tapered zones using A-Blocks and H-Blocks.
ArmorBlock gives program managers and range integrators three strategic advantages.
Higher Safety Margins. The wall system contains rounds where they hit, which reduces ricochet concerns and halo damage.
Lower Lifetime Cost. Less fragmentation leads to fewer repairs, fewer rebuilds, and lower downtime.
Faster Path to Compliance. ArmorBlock supports the design work needed to meet UFC and USACE ISAR requirements without stacking multiple protective layers that complicate construction.
Indoor ranges are long-term assets. ArmorBlock keeps them that way.
