    Not sure if this is the best test. Barrel length, rigidity, and profile all play a part in this.

    Found that out myself this weekend.

    Friend of mine had a Colt 6720 cut down to 10.3'', by ADCO, and left his M4 handguards on it. Has about a half inch less POI shift than my 11.1'' gun does.

    He's using an NT4 as well, but there are too many variables to be sure it was the FF guards. I'm just saying that markm may very well have been right.

    Other than that... FF is the way to go. IMHO.

    I'm violating a very basic rule, I know, but I got to this point and couldn't read any more.

    I'm not suggesting you ditch your friend entirely, but listening to him talk about weapon components, their capabilities, and what they may or may not do for a shooter is probably as pointless as a discussion about what male masturbation FEELS like....with one's mother.

    If he's pressing bad gouge like that, he's a believer, which is another way of saying that he represents all the good intention that roads to hell are paved with.

    The day-to-day Marine's quals are made at the 200 & 300yd line, not at the 500. A good shooter that mind-****s himself at either may save his ass at the 500, but the constant assertions of 7 of 10 hits at the 5 are not the trend.

    I will continue to freefloat my ARs. The probability of me actually shooting the guns and is far greater than the probability that I'll find myself pressing down on the handguard with one knee and pulling up on the barrel to test how much the bbl nut can handle.

    I shot 5 of my ARs this weekend. Confirmed zeros on 4 and the 5th I ran hard in drills (NGA X7) got it so hot that the FF tube burned my left hand right through my Oakley FR gloves.

    He said so, I'm sure.

    I don't use FF rails either. I used a 16" BCM with a 12" DD Lite upper as a pogo stick and it broke the barrel nut. Since then, I use my plastic handguards and FSB to keep my gun together.

    Kinda moot, innit?

    Taking that sentence as it reads, "should be" makes it open-ended; there was room for doubt, hence the need to question. We can stick to technical merit as a stand-alone without getting into the fuzzy-headed thinking and gun-rag article absorptions rates of another party.

    The last time I broke a barrel nut that didn't include overcranking on it, it was while jumping up to the moon to punch holes in it. With my weapon in hand; I banged it across my knee when I landed.

    Using only one leg.

    Uphill, both ways.

    Ergo, all those craters you see. Sorry....

    This is how tall tales get started.

    OP,

    The ONLY case I can and do make against using a quality free floating rails system is the cost.

    I have two Colt 6920's that I use (one I use, and one is a spare) as a LE Patrol Rifle, get to and from work w/o issues, home defense, and because I enjoy shooting the things.

    My guns are used well inside of 100 yds. I only needed to mount a light. My optic (Aimpoint an T-1) is mounted on the receiver (where else) so the type of rail does not matter to the optic.

    I went with the Magpul fore end and a mount-n-slot light mount w/Surefire G2x. For me, it works.

    I have used other shooters guns equipped with quad rails and tube rail systems from DD and Troy. The last thing I would be concerned about with the guns I used and/or examined would be the durability of the rail. Short of beating the things with a hammer, and even then I don't see durability to be an issue.

    The free floating rail systems bring a lot to the table. I feel the only real negative issue to them is the cost. For me, the cost did not justify the needs I had for these particular guns.

    While I don't intentionally abuse my guns, they don't get babied either.

    The durability of the rail systems I've handled never even crossed my mind when I was checking them out.

    Your friend has an over inflated opinion of self worth. Don't listen to his advice.
