m4 barrel
 

What company makes the best 6.03 tight bore m4 barrel and where would I be able to purchase one?

Also who makes the best 1 piece hop-up for a G&P m4?

Thanks in advance

You cant go wrong by purchasing the Prometheus 6.03 tightbore, one of the most expensive...

Systema makes excellent 1-piece hopup units...

You can purchase these though monthly group orders (contact Jugglez) or directly through the retailers, located on the top bar.

I got two Madbull 60.3mm tightbores a few weeks ago, one for myself and one for a team mate. So far they're proving to be excellent, both went into ICS M4s and have tightened up accuracy considerably.

I got them through www.evike.com along with a bunch of other stuff, but I'm not sure I'd recommend them to buy from. Their shipping charges to Canada are outrageous.

I have the Prometheus 6.03 tightbore and the Systema Hop up with the O-rings on it..good combo (on a G&P M4).

FWIW, www.airsoftparts.ca now has the Madbull 6.03mm barrels in stock.

Those barrels are really good. For more than half the price of the prometheus you get a quality barrel which is also 6.03...

Prometheus inner barrels are made out of stainless steel tubing where as Madbull uses aluminium.

I don't find much difference between a 6.04mm and a 6.03mm inner barrels. I use Prometheus and KM barrels in my guns.
