Need help choosing a tightbore

If your barrel is too long for your mechbox, a 6.01 will cause MORE friction than something like a 6.03 due to the tighness.

If your barrel is the proper length and a 6.01 you'll see vast improvements in range and grouping. (I'm talking about PDI barrels, I haven't dealt with any other 6.01)

The propulsive force on the BB is the air behind it as it tries to escape.

If there is nothing blocking then it is free to move and that energy is dispersed into the open.

Try it with a garden hose with a marble and a golf ball. Plug up the hose with the marble (if you can) then turn it on. It'll spit it out at a decent speed but if you jam that golf ball in there you're gonna have either A) a massive structural failure in the hose if your water pressure is good enough or B) a hell of a hole in whatever object the golf ball hits.

So... lemme get this straight, 6.03 is the best overall. I have a M4 that I am gonna probably convert into a DM rifle, so I need a M16 length barrel, will my mechbox be able to handle it or should I get a bore-up kit?

You'd just need a non-ported cylinder AKA an M16 cylinder in your case.

Ok, sweet, all I needed to know.
