Doing the Mini-30 Strut

Using a barrel stabilizer on a Mini-14 or Mini-30 rifle provides two primary benefits to the shooter. First, the typical clamp-mounted barrel stabilizer helps to dissipate heat away from the barrel. The Mo-Rod, which uses custom clamps that encompass the barrel's diameter (more surface-to-surface contact), provides for rapid heat dissipation by using anodized alloy clamps, a material known for its heat dissipation characteristics. Secondly, as a semi-automatic barrel heats up from repeated firing, the barrel can develop a condition known as barrel whip. This causes just enough movement in the barrel to produce stringing on the target. To control barrel whip, a barrel stabilizer, like the Mo-Rod, is designed with a 3-point anchor system to hold the barrel in its rigid position, thus providing more consistent targets.

These look really good on a rifle. I'm not knocking them, I just have a little trouble with the logic behind them. Allow me to play "Devil's advocate".
1) Barrel whip. - As I understand it, all barrels whip to some degree as a bullet travels through them. Short or long, thin or thick, hot or cold. 2) Clamping something to a barrel isn't really a good thing for accuracy. 3) Heat dissipation - I'm sure, if fired enough to get hot, these clamps would draw heat away from the barrel. Starting at the point where they touch. This would probably cause a tight spot at each clamp since those spots wouldn't expand as much as the rest of the barrel. I really don't see that improving accuracy, either.

I've never found a mini to be a target rifle and maybe these struts don't hurt their accuracy. I just don't understand how it helps.
