They are easy to install but you must re-zero the rifle after installation. Because as Dillinger stated it will change the barrel harmonics by installing. But once you have done the re-zero it will stay the same unless you change something else that has contact or effects the barrel harmonics. The free float requires front sight and barrel removal.
The Surefire looks like a great rail. Im guessing it is a Free Float, it did not specify. I will give that one a hard look and do some reading.
Most of the rife length rails that i have found are in the 15-17oz range, without spending over $300 anyway. There are alot of good options out there, i still have some research to do.
Thanks for all the input fellas! That was a great post by Dillinger!
