Tightbore inner barrel
 

I'm currently looking for a tightbore inner barrel for my AEG Lonex M4 and I've narrowed down my search to:

Deepfire stainless steel 6.02

Madbull Python 2 6.03

Guarder 6.02

I'm wondering which barrel I should buy.

Madbull, it's the best barrel for that price, $30 I believe.

The problem I've come across with madbull is the coating wears out after a while :(

prometheus 6.03

prometheus eg 6.03 if you want to spend the money. madbull's shouldn't wear out that quickly unless you're running sand paper through it.

Durchmesser absolut - Absolute Diametre
Schwankungen vom innendurchmesser - Fluctuations in Diameter

Guarder wasn't in this comparison, but apparently Madbull barrels are both tighter and more consistent than Deep Fire. If you have the money, Prometheus was the most consistent of the 20 types of barrels tested, 4 times more consistent than Madbull.

Well, let's be honest here, being better than deep fire isn't saying much...

I'm not a fan of the Madbull barrels, I only use one in a gun with a hop up unit too tight for Prometheus. The whole point of the coating is to hide those machining imperfections. The coating will inevitably wear away over time because we all know our loading hands aren't the cleanest things when we go to a game.

...you use your hands to load your mags???

I use my hands to put BB's in my speed loader.

Prometheus barrels - I put that shit on everything.

But seriously, as good as Prometheus barrels are, and despite what a lot of people think - the surface finish inside a Prometheus barrels is nothing like the polished exterior. I'll be using the HS5 Barrel Lapping kit on some to do some testing.

I would like to hear what the HS5 lapping kit on a Lonex with a polishing job does compared to a Promy.
