Matrix / AIM Lipoly Ready 8mm Complete Gearbox for M4 / M16 Series Airsoft AEG (M150 / Front Wiring)
by John M. Date Added: April 16, 2009
Ok so I just got this gear box and installed it in A Classic army M4 RIS. So based on looks I would give it a 6 out of 10 the metal they used to make the gear boxes is not up to par, but what do you expect from a 110.00 gear box. I gave it a 5 out of 10 for ease of use installing. The pins line up fine but the body pin above the trigger was not on center had to do a little sanding. not to big of a deal, but still a pain. After installing and hooking up my battery (9.6V 2000 Mah Elite Cells) I crono-ed my gun first 5 shots of excel .20 std was 453fps. After that I tried shooting .25 Excel std and avg 415fps so I gave that a 10 out of 10.

Just a note the piston had no grease in it, but other than that this thing in a beast!

Overall 8 out of 10 . Not a bad deal for the money!
