Who can tell me the pros/cons of free float rails? Interested in buying the Larue 6" rails. I will not be mounting any lasers or optics on the rails, just a grip and light. Wondering if theyre worth the money...

The advantages of a freefloat rail system are that they remove extra pressure input on the barrel, and allow for mounting accessories. This is mostly useful for precision shooting.

If a light and grip are all that are to be mounted a non-freefloating rail system would work just as well. If sights are to be mounted a free float system may be prefered.

LaRue is known for making top of the line stuff for AR platfrom rifles. Other respected manufacturers are Daniel Defense, Troy, and Knights Manufacturing. Others who are functional but do not seem to have the same following are MI, and YHM.

FF rails are kind of like pencil's, they all pretty much do and preform the same way with the exception of a few. The LaRue system "probably" locks up the tightest being it is a one piece system. However your not mounting an optic so I would recommend the MI FF rails.

Pros: Slightly Improves Accuracy (gives the user the ability to add accessories)
Cons: Adds weight to the rifle.
