  The Story

  In collaboration with BBA (Bristol Based Airsoft) and Cheffington (Ian from Firesupport UK), we spent over a year trying countless bucking prototypes, materials, and contact patch shapes to bring you the best in GBB Hop-up engineering.
  It all started with an idea; what if the bucking had a tighter initial wall to help slow down the BB to more consistently sit at the same point on the contact patch?
  After a lot of production and waiting we were finally able to test out this theory, the difference it made was phenomenal.

  The Problem

  A big issue a lot of GBBRs have is something called over-chambering;
  Aquí es donde el BB se empuja de manera inconsistente y ligeramente más allá del punto óptimo del parche de contacto cuando un GBB realiza un ciclo.. El peso y la velocidad de la masa ciclista es bastante para poner encima de una bola de 6 mm y una funda de goma. (el salto de salto).

  La solución

  El Crimson Bucking soluciona este problema al tener una apertura inicial gruesa y duradera.. Se necesita una presión considerable para que la bola se presione contra la goma de salto., lo que ayuda a evitar que el perno y la boquilla empujen la bola demasiado lejos de los puntos de contacto..

  Los beneficios

  Esto permite una trayectoria de vuelo mucho más consistente que, en última instancia, hace que su experiencia de disparo sea más predecible.. No te preocupes más si tus bolas volarán un poco más hacia la izquierda., bien, arriba, o abajo.
  Junto a esto también tenemos un parche de contacto con dos puntos de contacto.. This shape with the valley in the middle helps align the BB totally in the middle, whilst applying more than enough pressure for even the heaviest of BBs.
  We also use a material called NBR to construct the Crimson bucking. This rubber is far more durable than your traditional silicone rubber, which could easily tear during installation.
  The Crimson Bucking will be sure to last you a good while before any necessary maintenance.

  We have tested the Crimson GBB hop-up bucking in a wide range of GBBs. Below is a small list of just some of the platforms we had great success with;

  • VFC AR/M4 variants (including the new EVO series)
  • VFC AK variants
  • VFC MP5 variants
  • VFC G36
  • VFC M249
  • VFC PPSH
  • Tokyo Marui GBB Pistols (a wide range from G17s, to Hi-Capas, to USPs etc)
  • Tokyo Marui MWS M4 variants
  • APFG MCX/MPX variants
  • APFGXM7

  *Descargo de responsabilidad; Results will vary depending on GBB used, recoiling mass, recoil spring strength, intended weigh used, ambient temperature, fps/joule targets, and gas pressure used.
  We have further degrees of hop-up buckings, both softer and harder, coming soon to satisfy all use cases.
