Stripped threads, missing screws, and loose accessories can quickly take an airsoft primary out of action. Arrow Dynamics M4 x 20mm Replacement Bolts provide a durable, direct-fit hardware solution for airsoft technicians, custom builders, and skirmishers maintaining their gear.
Durable Construction & Precision Threading
Manufactured to standard metric specifications, these M4 (4mm diameter) by 20mm length bolts are crafted from high-density, corrosion-resistant alloy steel. They feature clean, uniform metric threading to prevent cross-threading and ensure deep engagement into aluminum, zinc, or polymer mounting points.
Essential Airsoft Maintenance Hardware
From securing outer rail segments, mock suppressors, and stock baseplates to mounting custom attachments onto M4/M16 series receivers, having the right length fastener is critical to preventing loose wobbles during game day. The 20mm shaft length provides ample clearance for multi-layer accessory mounts and specialized internal bracing.
