I'm debating if I should use FF rails anymore

[Mossy Man]

I don't use scopes that often.

I use mostly irons and and RDS.

I don't bench shoot, mostly off-hand.

I'm currently running a 16" with a FF MISS12G2, which is a great rail.

But if I tighten up on the sling enough the front sight shifts some; it is noticeable just by looking at my RDS when i sling up.

I think a mock dissy might just be in my future...........or maybe a 14.5" with a carbine gas system and A2 fsb.....

are rails just for ninja factor for most people?

i'm starting to wonder if the benefits are actually enough to offset the drawbacks.

Your just a strong man. Us weaklings ise ff just fine.

I had a magpul mid length handguard on my Noveske. I installed a centurion (mid cut-out) rail on it & like it for several reasons. I have a FSB & the new rail's longer than the handguard, it covers the FSB pretty well. Makes it easy to bench rest & less barrel to burn my fingers on. I have nothing hanging on the rails, but use ladder style covers & I use an Aimpoint T1. I see no reason to hang a microwave oven, timing light & machete off my rail, lol.

get the front sight off of your rail and back on the barrel where it belongs.

This will solve your problem

And yes, that tugging on your sling will pull the barrel too if the rail the sling is attached to is not free floating.
Thus the concept

the rail is free floating, and it only affects my BUIS, but it still kind of makes me wonder why am I using a rail because i don't have anything attached to the rail except my sling.

I suppose as long as I always use my RDS its ok, but.....

That is my point.

With a FF rail, the deflection you experience when using a hasty sling (or similar) stance is isolated to the rail. If the rail is not FF, then it will be attached to the barrel ( a FF rail is not), and will pull an otherwise zeroed barrel off of its POA - and there goes your POI, which means no bacon for mama.
This won't happen with a FF barrel

If your slinging that tight, you might shift the barrel. Have you thought about keeping the FF, but using a barrel mounted front sight?

[SloChicken]

PS you don't have to hang crap off of a FF rail- look at the hogue tubes for an example of simple FF rails

It sounds like you may have a quad rail, and yes, that may not be necessary.

This.

Like I said earlier.

Yes and your the only one that is hipster enough to realize that. You single handedly figured out what should work for everyone that is not a ninja.

[TeeLiberty]

If you want a quad rail, the MCTAR-20X G2 is a great option as it fits around the A2 front sight. Sling up as tight as you like, and you should only deflect the FF rail, not the A2 front sight. BUIS mounted to a rail should really be considered backup.

Just my two cents ... YMMV

[socom2shooter]

I dont use rails. My only gun that has them is my socom 2. I dont like them much

[Grumpyoldretiredcop]

I've yanked the rails off most of my ARs and replaced them with M4 forends - and my back hurts a little less at the end of the day. The two exceptions are my 11" barreled AR pistol, where weight isn't such a consideration, and my JR Carbine, where replacing the Troy rail adapted by the PO with a modified YHM handguard was about the only viable option.

Do a 16" dissy with a FF rail

Do a 16" dissy with a FF rail

I recently picked up a PSA upper with MI FF setup. For now I have BUIS mounted on the rail, but I'm seriously considering going mock dissy - pretty much just getting rid of the front BUIS and putting on an A2 sight.



The barrel is 3/4" (.750") where it comes out from the handguard, 11/16" (.688") closer to the muzzle. How much room is needed for a standard sight? What brand do you like?
