Default Question Time. ??Harmonics??

I have a question about Barrel Stabilization.
Seems on a Mini-14 the thing to add is a stabilizer bar to stabilize harmonics or what ever.
While on an AR the thing is a free float barrel, also with other rifles.

Why stabilize one and allow the others to float? Anyone understand what I am asking? I got myself lost.

Just a thought but could it be the fact that a Mini 14 is piston driven versus the AR's DI gas system.

What about Piston AR's? That is the reason for the question.

Isn't the mini-14 of different construction than most rifles? You could get an aftermarket stock, have it milled and glass bedded. That would float the barrel to a certain degree. I believe the thing with the mini's is that it is much cheaper to add the stabilizer than to have a ton of work done. The mini is an ok shooter without either, so why do so anyway? Just to have a 5/8 inch moa brought down to 1/2"? I'm not sure how much it will cost to make a mini into a tack driver, but I am confident it is much more than what it is worth. Just sayin. Wait for Bear, he can tell you tons more about this as I am just talking out of my bdh.

I think it is that the piston system on teh mini makes the barrel flax more. I am unsure that is what makes the ak-47 lass accurate than the ar-15.

I am no mini expert. I am sure they will come along shortly.

That question is above my pay grade but I would suspect that a piston gas system would reduce the effectiveness of a free floated AR barrel to the extent that the piston itself adds vibration to the barrel. There is no way to isolate the piston from the barrel hence the stabilizer you would see on the Mini.

But don't listen to me I am only speculating...hopefully some of the other guys aren't too far into the egg nog yet to give a more rational answer...

I am thinking what Shihan is referring to is the small weight that you can move back and forth to tailor the barrel harmonics for maximum accuracy. I have seen these weights on several rifles and have always found them to be snake oil. If you have the proper load worked up for your rifle, you should not have to worry about harmonics. That however is just my opinion.
