tokyo marui upgrades

[SimonDJXC]

I am thinking of buying a Tokyo Marui Airsoft M4 CQBR, and will defo get a spring change to 340fps BUT whats the minimum i need to do on top of that? Is there a cheaper alternative on the market?

[Galvatron]

Is it not better to get the gun first to confirm the muzzle energy or is this a used gun that has been chrono tested?

 

I assume you're talking about the NGRS version of the M4 CQBR and not the GBBR or are you talking about the buffer spring with a GBBR?

 

What's the context of a "cheaper alternative"? Adjusting your fps or a less expensive gun itself?

 

You don't need to give War and Peace but it really helps when you're more forthcoming and transparent with details.
