About M4-7 Extension Tube: (link)
Mad Bull Licensed ACE Buffer Tube model M4-7 is fully licensed by ACE LTD. USA.
This incredible new design allows for easy storage for your lipoly battery. No longer do you need to use a battery box, battery pouch, or any other style external battery option.
This completely new design takes in essence the previous designs and takes it to the next level with several new features. The end cap no longer needs a small screw to remove which can take extra crucial playing time. It now simply just twists off for quick access to your battery!
The M4-7 tube includes full ACE licensed trademarks, stock position markings, and quick-detach sling adapter (swivel not included). Made in Taiwan with much higher quality materials than the cheaper China "Hong Kong" made buffer tubes. Made of tough T6 aluminum and only weighs 3 ounces that's half as much as other brands!
Fits any buffer tube lipos and fits best with the Mad Bull Lipo and SOCOM Gear Lipo type.
*Remember that the back of the lower receiver must be cut to 25mm for installation of any lipo tube and crane stock setup. Lipo and sling swivel not included.
