Vang Comp vs Regular 590A1

[u/PuzzleheadedLuck5240]

I was recently watching the Garand Thumb video on the Vang Comp 870 in which he compared it to the 590A1. The results found in his tests were that the 590A1 was actually slightly more accurate both with federal flight control and bad sterling buckshot.

Of course this is one test with 1 gun so results would likely not be the same from person to person, but does anyone actually have experience with the Vang comp?

In the video he mentions the 590s excellent barrel harmonics which is why accuracy difference is negligible. Does anyone know this to be particularly true in their experience?

Vangcomp lengthens the forcing cone which creates a internal "choke". Its going to have a similar effect as a thread in choke but you see better patterns at greater distance. Chokes deform the shot and make it fly more irregular.

Someone will come along to argue that chokes are better or do the same thing and they probably haven't tested or actually held a gun that has been modified. That being said for most people a choke will change the pattern at acceptable ranges and thats why we don't see similar machine work going into other firearms, people prefer a cheaper price point or the versatility of chokes, over the ability to throw a ten inch group of 00 buck at 25 yards.

Flite Control and Versatite loads also give very similar (some argue better) results over vangcomp or chokes, and considering the time and money for machine work most of us probably could get away using it.

The vangcomp system can't be done on my 1301 because of its chrome lined barrel, so I just shoot cheap ammo and keep a few boxes of Flite Control around for more important work
