[QUOTE="z06man, post: 1465709, member: 6182"] The free float rail keeps you from putting pressure on your barrel when you are holding it, have it on a bipod, are using a sling for stabilization or basically anyway you are going to support/control the forearm of the rifle. The pressure will slightly bend the barrel and also effect the harmonics. These will shift your point of impact from your point of aim. Often it is not a big effect, but it will be there. For some rifle/load combos it can be huge. To get the maximum accuracy from your rifle, you'll want the FF rail. [/QUOTE]
