I am going to be modifying my Commando M733!!!
I asking everyones opinion on the parts I plan on puting into it? This is the first m4 I am building, and I know about the possibilities of gear box cracking over time and bad hop up!!!
My goal is to having it shoot between 390 and 400fps, with the most durable internals possible, and most accurate. I know lots of you are going to become cranky and think alot are unnessisary.
m120 spring
Metal Bushings
metal spring guid rod with bearings
systema bore up cylider kit
silent head set
systema low resistance wiring to rear of gun
Systema torque up ratio kit
However, how do you feel about the parts I feel that are opitional such as
systema one piece metal hopup
systema hop up bucking
tight bore barrel
or even a new mechbox?
