I just picked up a Ruger 10/22 carbine with the walnut stock and I am interested in free floating the barrel. Before I alter my stock, or more likely buy another factory stock to alter ( I like keeping my stuff original if possible, or at least the ability to change it back to original) Anyways, I digress, as I understand it free floating a barrel improves barrel harmonics which in turn improves accuracy. Seems simple, so simple I wonder why they don't do it at the factory. Why do they put a barrel band on the carbine model? (and a junky plastic one at that) Are there any negatives to free floating a barrel?
