Overview

Product Overview

The King Arms Input Valves with O-Rings for 4.5mm and 6mm M1 Spare Parts is a premium, factory-spec maintenance and repair kit engineered to maintain flawless gas seals and airtight pressure containment across King Arms M1 Carbine platforms. In gas blowback (GBB) and CO2/green gas magazines, the input valve is a high-stress point exposed to intense cooling cycles, dirt ingress, and pressure spikes. Standard or degraded valves often suffer from dried-out seals or distorted internal pins, resulting in slow, persistent gas leaks that ruin shot consistency and field reliability. King Arms circumvents these pressure losses by manufacturing these input valves from high-tensile brass, paired with dual-layered high-density nitrile rubber O-rings that resist freezing, swelling, and chemical degradation from silicone oils. Designed as a universal factory-direct spare part, this kit ensures total compatibility with both 4.5mm airgun (.177 steel BB) and 6mm airsoft iterations of the King Arms M1 Carbine magazine line. For B2B trade stockists, custom gunsmith stations, and specialized airsoft pro shops, this essential small-part maintenance assortment represents an indispensable, high-turnover service component to keep customer platforms operating at peak pressure efficiency.

Legal Information

1. A Safe & Regulated Hobby
  • Recreational Nature: Airsoft is an organized sporting activity focused on teamwork and target play, much like paintball.
  • Safety Tested: These items are engineered to discharge lightweight 6mm plastic pellets that are non-lethal and designed specifically for hobbyist use.
  • Legal Status: Under the Firearms Act 1968 (Section 57A), airsoft products are not considered firearms because they operate at very low energy levels.
2. Muzzle Energy & Safety Limits

  • Fully Automatic Models: These are capped at 1.3 Joules.
  • Single Shot Models: These are capped at 2.5 Joules.
  • Toy-Like Characteristics: Because they fire only plastic or part-plastic spherical missiles (max 8mm diameter) at these low energies, they are legally recognized as safe recreational tools.
3. Restricted Professional Ecosystem (B2B)

While individual buyers at retail shops must provide proof of "Defense" (such as a skirmisher membership) under the VCRA Act, iWholesales operates at a higher professional tier:
