straight copper barrels

Unread postAuthor: Eddbot » Sun Mar 30, 2008 11:55 pm

ok, i keep reading posts where people claim they can hit tiny stuff from really far away, so they must have perfectly straight barrels, but when i go into ace, i look at all their 3 foot long pieces of copper, they're bent really badly, and i can't find any that aren't, does anybody have a way of straightening barrels, or a site where i can get a reliably straight pipe

I found a really straight piece of copper (5 foot long) at home depot. Had to search through like 20 of them to find it. You could try to bend it carefully with your hands.

Hard, flat surface such as a concrete floor.

Just keep rollin' rollin' rollin' rollin' (what?)
Keep rollin' rollin' rollin' rollin' (c'mon)
Keep rollin' rollin' rollin' rollin' (yeah)
Keep rollin' rollin' rollin' rollin'


Yea! :D

What makes you assume straight is the answer?

Consistency is much more important.

If all of your shots go to the same place (even if its 2 feet to the left) you sight for that point. (the center of the grouping)

I told you, hard, flat surface, and keep rollin', rollin', rollin' :)

That's how the efficiency God* JSR does it.

it's cause of the way they store it, instead of lying it down on the floor, they decide to save space and prop it up on a rack, as a result the pipe bends from it's own weight

and crowley, i don't think i have the patience for that (or a clear space in the garage :roll: )

Take a look at the "L" copper tubes at Lowes...not "M". Tube walls are thicker with "L" rating and many are pretty darn straight.

Sieg Heil! But I actually use the Urban Assault Vehicle remix, I find it gives better results :)

As has been pointed out though, barrel straightness has little to do with accuracy ;)

I stick to PVC barrels, and sleeve them inside chrome plated curtain rods (because they're dead straight). I use these types of barrels for my hybrid and pneumatic snipers, very accurate with marbles, I can hit Coke cans @ 25m every time.

I know where your coming from, i cant stand any barrel which isn't perfectly straight, just isn't as precise

Bugger rolling :P

How bent it is is secondary to having dents in it for me.

The two generally go together mind you but when I buy 15mm pipe I take one of the adapted 15mm T's from my cannon with me.

If I can slide it all the way down a pipe without any sticking points it's a pretty good sign it's dent free. A slide coupling would probably be as good.

None of them are perfectly straight but if it hasn't been bent so much that it's become dented you can get it straight enough just using your hands.


Mind you I've seen some ghastly bits of copper attempting to be sold, the bundle of pipes looked like a wilting bunch of daisies :shock:

Probably not an option but B square sells a shot gun barrel straightener.... don't have the time to find the link right now but Google it 8)

I know sighting stuff in kind of sucks but if you set the can up and then behind the can set up a large piece of cardboard it makes it a lot easier. That way you can see where your shots are landing and it will allow you to correct for the crooked barrel.

Copper is fairly soft and easy to bend. So even if you straightened it you would have t be very careful wit hit so it didn't bend again. If accuracy is a factor use a steel or brass barrel...
