Barrel Upgrade

[flighttime95]

I am somewhat new to airsoft in terms of internals and such, and I was wondering if I could get some tips on upgrading the barrel of my gun. I currently have a G&G GR15 Raider CQB AEG, and I want to try to increase range and accuracy. Will a tighter bore barrel help increase the accuracy of the gun, and does the length of the barrel have an effect on range? I do not want to ruin my gun or degrade its current performance due to a lack of knowledge of upgrades, so any tips or advice would be greatly appreciated.

Thanks.

A tight-bore barrel is one of the best upgrades you can do for a gun. It will increase accuracy and therefor your effective range while adding no stress to the gearbox. Many also claim that they have seen increases in velocity with tight-bores because the BB is a tighter fit in the barrel and therefore less air is lost around it.

Knowing all of this, it is also important to know that there are more important things than the inner diameter of the barrel (for example 6.03 or 6.01). What's far more important is the general quality with which the barrel is made. For this reason I personally like Prometheus or PDI barrels, as they are both made of a steel and are well made.

My advice to you is to get a Prometheus barrel, and if you don't yet want to pay that much for one, then a Mad Bull barrel is probably your best bet while on a budget (in my opinion).

Finally, regarding barrel length:

Barrel length does not affect your accuracy.

Now before you completely discount this as being false, I mean that barrel length doesn't seem to have any impact on accuracy past roughly the 247mm mark, which is (IIRC) a 7 inch barrel used in G36c's, P90's, and certain M4 barrels.

Any noticeable increase in range or accuracy attributed to a longer barrel is not because the barrel is making the weapon more accurate, but rather it is because it is providing an increase if velocity, and therefor the BB has less time to be affected by wind/other factors between it and its target and again, will simply go farther because of the increased velocity.

So, to recap everything I've said:

1. Barrel Quality is more important than inner diameter. (I recommend 6.03 Prometheus barrel, and if too expensive, then Madbull barrels).
2. A longer barrel will not boost range or accuracy from a shorter barrel so long as their FPS is the exact same.

Just as the guy before me said but make sure you have a good air seal 1-2 fps deviation and get an r-hop.

Rhop may be a little advanced for someone not familiar with internals. Hell, I could probably do my P90 in my sleep and I still won't touch an rhop.

I echo what Lancer said. Past 247mm, what's going to matter more than barrel length and diameter is the quality of the barrel. Madbull is popular because their stuff is fairly inexpensive, and for that price it's an amazing barrel. Hell, even when you compare it to barrels in higher price ranges, it's rating really diminishes to "great".

If you're building your gun into a high-dollar, lots-of-work reach-out-and-touch-someone gun, then I say spend the extra cash on the Promy. If you're just looking to get a little something extra out of a stock/moderately upgraded gun, get the Madbull.

Clandestine airsoft sells rhopped prommy barrels for like 70-80 I believe and that will give you great accuracy and extreme range also the rhop is preinstalled.

Thanks for all the info guys!
