MadBull Ultimate Hop-up Chamber for M4/M15
MadBull's Ultimate Hop-up chamber for M4/M15 is one of the most versatile and unique hop-up chambers on the market. In addition to designing a very functional and reliable chamber, they have added three very useful functions, the chamber lock, redesigned adjustment know, and the ability to add an LED tracer unit.
The Chamber Lock, catches BBs as they enter the chamber to prevent them from falling out when the magazine is removed and helps to ensure proper feeding into the chamber. This function can be disabled per user preference.
The redesigned adjustment know is located at the rear of the chamber instead of on the side (much like a E90 or X36 adjustment knob). This makes adjusting your hop much easier.
MadBull's LED tracer kit for the Ultimate Hop-up (sold separately) allows you to install the LED directly to the hop-up chamber which gives you an internal tracer kit and no need to add a "silencer" style tracer kit to the outer barrel.
This is definitely a worthwhile upgrade for your M4*
