Hi Guys, need to pic your brains, the inner aluminium barrel for the air soft gun, how many holes should it have in it?

The reason I ask is that I'm doing the barrel extension and Im putting in a new inner sleeve to compensate for the extra length of the gun barrel.

thanks in advance Foxy

its largely a function of the length - the shorter barrels of the Pz III and IV don't have any holes.
The barrel at the top is from a Pershing, the one below it is from a M41 (I think?)

Hope this at least gives you some idea
Mart

cheers Mart, the reason I asked is due to the fact that the original has two drilled in it and I have only read about the one, just wanted to clarify which was correct, looks like I need to drill two holes in the new one
Thanks for the piccie

Just ripped the barrel out of my Matorro Tiger - its 238mm long with 2 holes, 1st at 55mm from the airsoft mechanism and the other at 75mm.
Interestingly they are 180 Deg. apart as opposed to inline, like on the M41 barrel

hmmm, does the BB in that one thats got the offset holes shoot further or is it still the same?

I had been experimenting with my jagdpanther. It doesnt seem to matter where the holes are aligned although blocking them will reduce range.

Im interested in this too.

I've got a creeping death turret on my Tiger, and want to replace the rather tacky barrel it comes with, with the metal one.

Does anyone know if the inner barrel fits inside those?

Cheers,
Rik

Rik I would say not because the metal gun barrel is more to scale than the plastic one

Thanks for that Fred

Im a bit of an airsofter when im not tanking (no sniggering at the back that boy) so maybe able to help with this.

When i first opened up my old Tiger I assumed the drilled hole in the barrel was to reduce the velocity of the BB to a safer "toy" level. But it maybe that the air chamber which the piston moves inside doesnt have enough volumn to completely fill the barrel on the longer guns. If this happens then the BB will begin to slow down before it exits the end of the barrel as it doesnt have enough "puff" to fire it out quickly.

Also with the weaker springs used in the HL tanks compared to "proper" airsoft guns, its possible they could also suffer from the dreaded "SUCK BACK"  This happens where the bb is still travelling down the barrel when the piston starts its return stroke in the chamber, and effectively begins sucking air from the barrel to fill the air chamber.

You could upgrade the whole firing mechanism of HL using airsoft parts easily available on ebay but you'll encounter the usual problems airsofters suffer from such as: spring power, air leaks, well made polished inner barrels, decent BB's and hop up (thats the back spin that keeps the BB flying horizotal for longer). Also I might want to start wearing eye protection as a bb firing @ 300+ feet per second can give you a real nasty bruise or break the skin :-X
