I posted a similar question in the armory, but it got little traffic. So I apologize in advance if you have already seen this, but....
How much does free floating a barrell really affect accuracy?
I am interested in doing a build one day with a 20" barrell, a nice bipod, and a nice scope. Nothing fancy, just something I can reach out there and take some longer shots with for fun.
I want a railed forearm for the bipod and for the looks of it, but I was wondering if I needed to go with a FF forearm since I'll be using a bipod.
I won't be trying to get olympic qualifying groups or anything, but I do want it to be accurate enough to have fun.
I floated my 20" and went from a little over 2 MOA to a little under 1 MOA. Of course I installed a two stage target trigger at the same time, so it is difficult to say how much I gained from just the float.
There a many ways to go about it and you do not necessarily have to put a railed forearm on to use a bipod.
Look at the tacked thread in the rifles, uppers, lowers, barrels and more forum. It will probably answer most of your questions.
Floating certianly won't hurt, and you will very likely see your group tighten up. Flexing the barrel from sling/bipod/support contact can made a difference. You can get float tubes relatively cheaply, so why not do it.
