Description
The TWS Hand Guard Barrel Bushing Set .670″ is the essential replacement or sizing component from Texas Weapon Systems, designed specifically for secure installation of TWS Gen-3 handguards (and compatible systems) on standard AK platforms. Priced affordably as a precision-machined accessory, this set ensures proper clamping and alignment of the handguard to the barrel, delivering rock-solid stability, minimal barrel disturbance, and reliable performance in semi-floated setups.
These bushings are critical for achieving the semi-floated design that reduces handguard-to-barrel contact, improving accuracy, heat management, and accessory consistency on M-LOK/Picatinny-equipped Gen-3 handguards. The .670″ size matches the most common standard barrel diameter on Russian-pattern AK rifles (measured approximately 1/4″ before the rear sight block), providing a precise fit without modification.
Key Features:
Precision-machined for exact .670″ barrel diameter compatibility (± .010″ tolerance)
Ensures secure, vibration-free handguard attachment
Supports semi-floated handguard design for better accuracy and reduced mirage/heat transfer
Durable construction (typical high-quality TWS materials for long-term reliability)
Simple replacement or sizing solution for TWS handguard kits
Specifications:
Barrel Diameter: .670″ (standard for most AKM/AK-47/AK-74 patterns)
Measurement Point: 1/4 inch before rear sight block (critical for accurate sizing)
Set Contents: Typically includes 2x barrel bushings (as referenced in TWS Gen-3 kits; confirm with your handguard package)

Compatibility:
Optimized for AKM-type stamped receiver rifles (AK-47, AKM, AK-74 patterns) with standard smooth front trunnion
Required for TWS Gen-3 handguards (Short Top, Long Top, etc.) on standard .670″ barrels
Essential when installing or replacing components in Gen-3 systems for proper clamping and semi-float
Will NOT fit Yugo-pattern, milled receiver, bulged front trunnion, or non-standard barrels without measurement verification
Always measure your rifle’s barrel diameter at the specified point to confirm .670″ fit (use calipers for accuracy; other sizes may require different TWS bushing sets if available)
Installation Notes:
Direct replacement in TWS Gen-3 handguard kits inserts into the barrel clamp area for secure fit
Reversible, no permanent modifications needed
Pair with TWS barrel clamp, wedge clamps, and piston guide tube for complete Gen-3 setup
Refer to TWS installation instructions (available on texasweaponsystems.com or in kit PDFs) for precise fitting and torque specs
