Well, honesty is the best policy so here it is. Tonight I sent thekrnel $15.00 for a trial issue of his barrel shroud, to which I will be giving reviews to the entire forum. Yes, I did pay for the shroud + shipping. However, if it works out that this is a good buy, I have come out ahead of the game.
Ask yourself, "what does a barrel shroud really do?"
Answer: It allows heat to escape the barrel so that you don't lose accuracy, and helps disapate that heat. Basically it acts as a heat exchanger for your barrel. Cold air moves over surface of the shroud as hot air moves underneath. The holes in the shroud itself allow heat to escape thus cooling the barrel = thus "maintaining" accuracy. This addition to your rifle will not IMPROVE your accuracy, only you can do that. All this shroud does is help maintain the accuracy of sustained fire.
It also acts, indirectly *as this is NOT it's primary purpose*, as a compensator by weighing down the muzzle of the weapon, thus reducing the muzzle jump. By doing so, it helps keep you on target longer and helps on follow up shots as well.
To me, as long as this product helps keep me on target and reduces heat and muzzle jump, it's worth $15.00 all day long.
A full product review will be forthcoming once I recieve the product, install and test it. BTW, "thekrnel" better be ready for more forumite orders for this product, if it's as good as it claims to be. If this shroud can keep up with me and is worth the price, you guys better jump on it as soon as you can. I'll let you know.
