The all new Airsoft Surgeon RWA 1911 R.E. Hop-Up Rubber for RWA / KWC / Cybergun / Elite Force Co2 1911 & Cybergun KWC Tanfoglio is a long awaited item that is designed to revolutionize the hop up and accuracy performance of the following series:
 

• RWA (SPS Falcon, Covert Ops, Recon) /
• KWC /
• Cybergun /
• Elite Force Co2 Blowback1911 series and
• Cybergun / KWC Tanfoglio pistols.
  
  Accurate for up to 70m without having to adjust the hop up dial that much. You will have to use heavier weighted BBs such as 0.36g type to make sure your KWC 1911 reaches its true potential. This is a must have for the owners of the above pistols which suffered from the lack of aftermarket parts for improving accuracy!
  
  *Note this item will not fit KSC / WE / Tokyo Marui 1911 series
