ZeroLok™ ARCA Handguards

ZERO FLEX. ZERO SHIFT. ZERO COMPROMISE.

ZeroLok is a full-length ARCA-Swiss handguard system built for precision rifles and DMRs. The rigid ARCA rail interface lets you mount tripods, bipods, and bags directly for stable support. Engineered to resist deflection and maintain repeatable zero under load, ZeroLok keeps accessories locked in for consistent, accurate shooting.

WHY ZEROLOK™ ARCA HANDGUARDS

Purpose-built for load-bearing performance.

ARCA handguards exist for one reason: to carry load. Unlike accessory-mounting rails, an ARCA handguard is designed to interface directly with tripods, bipods, and support bags—so the rifle is supported by the rail, not stressed by it.

LOAD HANDLING

Full-length ARCA-Swiss rail integration for direct tripod, bipod, and bag mounting
Continuous ARCA interface provides broad contact and consistent engagement
Built for positional shooting, barricades, and supported fire

STABILITY UNDER LOAD

Geometry engineered to resist deflection under applied load
Rigid structure controls movement during hard support and recoil
Designed to remain stable when pressure is applied forward of the receiver

ACCURACY PRESERVATION

Maintains repeatable zero with mounted support equipment
True free-float design protects barrel harmonics
Consistent return-to-zero shot after shot

WHAT ZEROLOK IS NOT

Not an accessory rail with an ARCA add-on
Not a lightweight grip-focused handguard
Not intended for cosmetic cuts at the expense of rigidity

No gimmicks. No unnecessary cuts. Just controlled rigidity where it matters.

WHAT MAKES AN ARCA HANDGUARD DIFFERENT

An ARCA handguard is built as a load-bearing support interface, not just an accessory rail. The ARCA-Swiss dovetail is designed to be clamped—hard—by tripods and support devices, spreading force across a long, flat engagement surface. That difference changes how a rifle is supported, balanced, and shot.

ARCA HANDGUARDS (LOAD-BEARING)

Direct clamping to tripods, bipods, and support bags
Fore-aft balance adjustment along the rail
Broad contact area to manage barricade and tripod pressure
Designed for precision, positional, and supported fire

TRADITIONAL HANDGUARDS (ACCESSORY-BEARING)

Built primarily to mount accessories (lights, grips, lasers)
Point-load attachment systems
Not intended for sustained clamping force
Optimized for handling and weight, not support load

WHY THIS MATTERS

When pressure is applied during tripod or barricade shooting, a true ARCA handguard manages that load through the rail system instead of transferring it unpredictably into the rifle. The result is greater stability, consistent support, and repeatable shooting positions—exactly what precision and DMR rifles demand.

ZeroLok is designed around this principle from the start: ARCA as the support system, not an add-on.

Technical Notice:
ARCA-Swiss interfaces are intended as load-bearing support systems for precision shooting applications. Performance characteristics such as rigidity, deflection resistance, and zero retention are influenced by multiple variables including rifle configuration, barrel profile, mounting hardware, torque values, support equipment, and applied shooting technique. All references to stability, load handling, or zero retention describe design intent and typical use cases, not guarantees of performance under all conditions. Always follow manufacturer torque specifications and safe firearm handling practices.
