The RS1 recoil spring is a drop in replacement for your standard recoil spring, and can be easily installed with a simple field strip. The spring is intended for high speed Hi-capa builds, and will increase the cyclic rate of your slide by forcing it back into battery more quickly. The spring is a shortened design, with increased tension in certain areas of the spring to ensure your pistol still cycles as reliably as it did with the original recoil spring installed.
The RS1 is compatible with Tokyo Marui Hi-capa pistols and 1911s, and other Hi-capa/1911 pistols based on the TM design. The spring is a non-linear design, with two different tensioned zones, intended to improve the gas efficiency of the cycle and make recoil control easier for faster follow up shots. The RS1 is constructed from high strength spring steel with a hard coating for corrosion resistance.

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff.
Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.
We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!
Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.
Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
