Lapco barrel tip thread and barrel tip question

Hi,

First, does anyone have the specs on the lapco barrel tip?

Also, does the different styles have an advantage or are they just for looks?

Thanks

The barrel tip threads are 7/8-20 (same as CP and older Hammerhead).
It has been debated that some tips either increase, decrease or do nothing to both roundball and FS but I don't think anyone has taken the trouble to test this out (I know I don't want to).

The folks at Carmatech seem to think they have a tip that improves FSR performance beyond 65 yards now.

Some time ago, I saw an interview with a French firearms inventor, and one of the things he learned was that if you timed the flash hider with the grooves, there was an increase in accuracy with their rifle due to the gasses leaving the crown first from the grooves and by providing them a more direct exit from the flash hider.

When I saw the artwork for Carmatech's new barrel, I had a feeling that is what they (he) was going for.

Could we achieve similar result by drilling porting hole on the end of the rifling?

Out of curiosity did the inventor works for GIAT?

As for drilling holes in the rifling, maybe. What is really of concern in the design of the French rifle was what happens to the gasses when they leave the crown and enter the flash hider. The bullet has to travel through that region so, the thinking is to reduce the turbulence in the cage. That being said, porting in grooves of the rifling with enough area could theoretically reduce the amount of turbulence at the crown but we also don't know if the Carmatech barrel will in fact form a seal that prevents air from bypassing the projectile (as is usually the case in ported barrel designs).

Something to consider though- it is extremely difficult to add porting to a rifled barrel.

As for the inventor, If I remember correctly, yes.

Considering the low amount of gas release by our paintball pneumatic valves, is the cage restraining enough gas to alter the flight of an FSR? Would removing the cage prevent the problem?

For the porting to be effective, it would have to line up with the rifling ...

As for GIAT, I never thought my taxes would improve my paintball game ...
