[Madbull] 3 in 1 Hop Up Chamber Unit with LED Module[Ultimate][Tokyo Marui M4 Version 2 Gearbox]

Description:

• Part No.: MB-HOPLED
• Another practical innovation from MADBULL, this new metal hop-up unit / chamber has 3 functions in 1! Designed by airsoft player Brian Holt, Madbull implemented Brian's idea with the following smart features:
• 1. LED Tracer Unit (Optional and Included)
  2. Chamber Lock (Prevents BBs from falling out when you eject magazine)
  3. Easy adjustment using new design dial for more stable hop-up
• This set also includes a free MADBULL blue 60 degree SHARK hop-up bucking rubber.
  

• Note that the chamber lock function works via an O-ring in the BB feed tube that goes up to the firing chamber. The O-ring prevents BB's from falling out of the gun when you pull the magazine out, which is normal in a Marui type gearbox. If you find this causes any problems for you, or you prefer that the 3-4 BB's in the feed tube fall out of the gun during reloads, you can simply remove this O-ring to disable the chamber lock function.

• New hop-up adjustment dial stays in place and won't shift from vibration during full-auto firing, giving you more reliable and consistent hop-up than in traditional guns with slide-type hop-up adjustment lever.

• And if you need one more reason to get this hop-up unit, Madbull tested this hop-up unit on the Echo1 M4 and got a 5% increase in power due to a better air-seal. So you get 4 benefits in one unit! Need we say more?
