Precision Inner Barrel AEG / GBB, 6.01 mm - 640 mm
Action Army Precision Inner Barrel 6.01mm – 640mm (AEG / GBB Compatible, Bridge-Type)
Push your build to the next level with the Action Army Precision Inner Barrel 6.01mm in 640mm. Designed for long platforms (KJW M700, M98B Barrett, AGM MG42, SR-25+, PSG1+ and similar), this ultra-tight bore barrel helps deliver stronger consistency, improved accuracy, and extended effective range—especially in semi-auto DMR and sniper-style setups.
The barrel is made from electro-chromed brass with a highly polished interior, reducing friction and keeping BB travel smooth. Thanks to its bridge-type window and smart cutouts, it works with TM-spec (Tokyo Marui) AEG hop-up chambers while also supporting AEG and GBB/VSR buckings—a versatile choice for custom builds and long-range conversions.

Key Features
- 6.01mm tight bore – reduces BB wobble for tighter grouping and more repeatable shots.
- 640mm length – ideal for long rifles and support-weapon style builds (M700 / M98B / MG42 / SR-25+ / PSG1+ and similar).
- Bridge-type design – compatible with TM-spec AEG hop-up chambers.
- Dual-compat cutouts – accepts AEG and GBB/VSR style buckings.
- Electro-chromed brass – durable material with a smooth, consistent finish.
- Polished interior – optimized airflow efficiency and smoother BB travel.
Performance Notes (Read Before Installing)
- Use premium BBs and keep them clean. Tight bores are less forgiving—dirty ammo or dusty magazines can reduce accuracy and cause jams.
- Clean the barrel regularly, especially after crawling, muddy games, or dusty environments.
- Match your air volume to the barrel. A 640mm barrel may require the correct cylinder volume (AEG) or sufficient gas/HPA output for stable performance (Cylinder:Barrel Ratio).
