Question fellas? I have come to the conclusion that I would like to ad a quad rail to my ar 15. The only problem is idk which one is the best bang for the buck. I was thinking the spikes bar rail, but I don't wanna have to remove the front sight post, and I want a heavy duty use rail. Are there any other options out there, and what are they?

Buy a Knights Armament RAS system on ebay that is being sold by someone who acquired an extra one. You can get them for around $70-$120

Troy makes a quad rail that works around the FSP as well.

First, do you want it to free float the barrel, or not? Second, do you want a quad rail that replaces your existing handguards, or one that's longer?

Quad rails are cool, but they add a lot of weight to a AR, I can tell you. In addition you start to hang a lot of stuff you do not need, adding more weight.

If I had it to do over this is what I would have gotten.

Still able to hang stuff, but a less weight on the rifle.

That depends on the quad rail the lightest Daniel Defense rails only weigh 8.5 ounces. The lite rails use their own light weight barrel nut that is lighter than the standard meaning the added weight is somewhat less than the weight of the rail. For comparison a MOE carbine length hand guard weighs 6.5 oz. Not a significant difference in weight and the DD rails are free float and more stable than the MOE hand guards. The MOE are a great deal less expensive though.

I have also hefted guns with portly 16 oz UTG rails, rails like that are not something I would put on my gun.

I just want the rail to replace the hand guards, I don't feel the need to have rails out past the front sight post, by the way I have a midlength 16in. I was looking at the omega rail and I really like that, Idk if I wanna free float it or not. Is there a significant difference in accuracy with the 2 different types of rails?

I have seen them, and they are nice, but do not have rails on them (extra cost).

The ones in the link are $329 and weigh 14.8 oz, not light by any means.

They are nice but expensive.

I like the YHM ones. See if there are some folks close to you that maybe would let you see some different ones in person and you can feel them and see what YOU like

I have a YHM drop in rail on one of my rifles, been fine for five years or more. If I was to buy another drop in rail it would be the MI GenII drop in rail. They weight 7.5oz, have four QD points and have a monolithic look. Made in USA, life time warranty, $125, MI is great for CS.

I have a Yankee Hill Machine on my AR. It is called the "smooth" rail. It has a full top rail and then a couple of inches at the end all the way around with rails. That way your hand has a smooth surface to grab during shooting. With less rail all the way around, you are less tempted to hang crap on the AR that really isn't needed. Then later if you want the full rail, you can add them on to where the smooth part is. Just buy the rails and screw then on.

Free floats are nice because they preserve the inherent accuracy of the barrel, removing the connection of the handguard and sling. If iron sighted, you don't move the barrel around changing the point of impact.

They don't add to the accuracy, a free float can not make a 2MOA barrel shoot 1/2MOA. That is entirely up to the quality of rifling, ammo, and optic, all of which can improve accuracy quite a bit. Then you'd have to ask, "Do I really need to?" 2MOA guns will hit a 10" circle at 500m, about half the lethal hit zone on deer or the enemy.

Of course, that's very sporting on prairie dogs, nearly guaranteeing a miss. Goes to "What range and target are you going to use the gun for?" That is much more important than "What rail do I need?" because the answer may very well eliminate bothering with a rail at all.

Guns are specified by picking the best cartridge and ballistics, putting that in the optimum barrel length, having the best optics and mount, then stock, grip, handguard, and trigger - literally in that order. Getting things mixed around means some shooters put $300 rails on $600 guns and the results are nearly identical accuracy and a $650 gun.

Work down the list and don't jump ahead, but if you decide to, it's your choice. Just suggesting be informed and make the decision you want.

If you are looking for a drop-in non free float, I'd recomend either a Troy MRF-DI or KAC RAS. I would not pay any more than $150 for the RAS. For a free float drop-in, I am very happy with my DD Omega.

For what purpose do you want a railed handguard for?

i have forearms from YHM, Knights, Daniel Defense, Larue, Vtac, Noveske, and others.

YHM are by far the heaviest and cheapest. good bang for buck if you don't care so much about weight, but they also don't have an anti-rotation device so if you mount a VFG on it and gorilla it a lot, it could rotate

Knights is expensive and most difficult to install, but has the coolest features

Daniel defense LITE is my favorite. very light. VERY solid. kinda expensive. looks good (if that matters)

Noveske is nice because it's small and machining is nice so that it doesn't hurt your hand. you can wrap your hand most of the way around it. it's also pretty light

Larue is solid.

I just wanna add a light a light and a ...............spikes havoc launcher to it!:D
that's why I was looking for something heavy duty lol. I know there not very useful but I would like to put it on my ar, plus I could take it off when not using it and put on a afg for home defense.

+1 on the Midwest Industries rails. They are cheap and will work well for what you are looking for. They have free-float and drop in ones.

I've got experience with both the JP VTAC float tube and the LaRue float tube, and really like them both. The biggest feature of the VTAC tube is that instead of being a quad-rail, it's a straight tube, and you simply attach pieces of rail where you need them.

I haven't used them, but have been favorably impressed with the Troy Battlerails.
