I have settled on everything I want for my carbine exept for the railed forend.Either the RAS or FF RAS.I can either pay more for the RAS and have ease of installation and no FF,or get the FF RAS,pay less and not worry about weight affecting my accuracy.But then it will be harder to install(I think).Help me people!!!BTW,how much would accuracy be affected from a barrel not being FF(I only really plan to put a TD vertical grip and some SureFire flashlight).

Thanks,Tyler

I am one of the people who think that a FF rail system is is not necessary on a CQB, defense, or training carbine.

If you want it, fine.  Just don't feel it's a big deal, or really going to affect your zero.


If you do want a FF type rail that is fairly easy to install, look at the Troy MRF.  I am seriously considering one for a carbine.

But I thought ALL FF rails installed the same?And exactly what is better about the Troy MRF than the KAC FF RAS(hope this doesn't sound offensive,its not meant to be)?

No offense taken.

I am not really saying that the MRF is better.  That's for you to decide.

I just meant that the MRF is very easy to install.  If you have a standard front sight post assem. you only need to cut off the delta ring, spring, and the c-ring.  If you don't have a standard front sigfht asem., you can just slide them off.  After that, it is really just a matter of running a few screws.

Check out MM's info/pics on it:

The accuracy difference is minimal and if you plan to use a light and a VG, then you're not building a target gun anyway.   The regular RAS is perfect for those applications...as is the YHM 2pc handguard system for about 1/3 the price.  Unless you plan to put optics on the rail, then freefloating won't do a whole lot for a CQB carbine.

Free floating is certianly not a "Must Have" item for a carbine. The tiny bit of accuracy gained from free floating will probably not be noticed on a carbine with a normal effective range of 300 yards or less. The additional weight of a Surefire and vertical grip are not going to effect any accuracy that you will notice. Now if its a accurized 16", 18", 20" barreled rifle using 4x or better optics then the story is different.  A normal RAS will do you just fine.

My thoughts exactly Dinger.

Yes...  I also consider RAS's limit (in terms of accuracy) 4x optics and 20" non target barrel.

Since I like changing the config of my weapon I like RAS over anything permanent. (except muzzle devices, thanks to NFA)

Exactly how hard to install is the KAC FF RAS?I know the regular RAS is super easy but since the FF RAS is a one piece don't you have to do a bunch of retarded stuff to get it on?And I am getting the picture that not as many of you guys(and the military)use FF rails,and rather prefer the normal RAS because of ease of intallation.Oh,I read on quarterbore.com that SEALs use the FF RAS.Is this even true?Well,I guess a normal RAS will be fine for me.Thanks for the help.BTW,about the SureFire,one quick question,is the model 951SU any good?

Thanks,Tyler

Mounting a Knights FF RAS on an upper


Clamp the receiver in receiver vise or barrel in barrel vise.

Remove stock handguards.

Remove flash suppressor (note: if you can't, the free-floating handguard cannot be installed, e.g., post ban with pinned & welded muzzle brake)

Remove taper pins front sight tower base. Slide front sight tower off with gas tube attached.

Remove standard barrel nut with appropriate wrench.

Remove barrel. Slide standard barrel nut off.

Slide new two-piece barrel nut/ Handguard tube lock ring onto the barrel.

Torque to correct setting with appropriate tools, lining up the barrel nut and hole in the receiver for the gas tube.

Confirm the alignment with bolt carrier and alignment tool.

Screw free floating handguard tube with its two alignment pins correctly installed into barrel nut/ Handguard tube lock ring.

Tighten with strap wrench.

Reinstall front sight tower and gas tube.

Reinstall flash suppressor.

Im the odd man out around here.  Unless its purely a precision rig, I have no desire free floating on my hard use guns..  The potential accuracy gain isnt worth the chance of a SERIOUSLY hard hit on the gun damaging the handguard nut or the reciever thread themself.

Blah.I dont wanna do that stuff just for a handguard.I guess its regular old RAS for me.And BTW,I'm not putting a magnified optic on it.Just and EOTech 552.Or maybe an Aimpoint M2 with a KAC mount.Probably EOTech though.Unless someone can convince me to get the Aimpoint...

All kidding aside, I think you should try both the Aimpoint and EOTech if you can before you buy.  For many people, myself included, the EOTech is a faster and easier sight to use.  For many, the Aimpoint is faster and easier.  I think you need to see which one works for you if at all possible before you decide.  You'll hear comments from both sides of the fence ranging from jokes to simply angry commetns, but aside from that each user should choose an optic based on its performance for that particular user.  Everyone is different and that means different optics systems will work differently for each individual.  Peer pressure or even the need for the latest or biggest trend shouldn't prevent you from getting the one that you are most compfortable using.

Aimpoints are for stodgy old men who don't know what they are doing or talking about anyway.  Don't be a dinosaur, get an EOTech!

BTW, I think the regular RAS is fine for99.9% of applcations for a carbine as well.  It doesn't matter, though.  You'll probably end up building a rig with a FF system in the future anyway.  It's inevitable!

I've tried and EOTech,but never an Aimpoint.No one has anything in WI.It was luck my dad found a NIB Colt Match Target HBAR in a gunstore.Otherwise All I've looked through is the cheap stuff.Bushnell Holosight(not one of the cheap ones),tasco,Nikon(expensive),BSA,etc...And there is 2,yes 2,AR dealers anywhere close to my area.One is 20 some miles away(but they have awsome stuff!!AK,SP1,Benelli CQB M1,etc...)I'm sure the EOTech and Aimpoint are both extremely good and the only thing that is really bugging me about the Aimpoint is that you NEED to get a mount.And they are all the price of a BUIS.So,I can either get the EOTech and get a BUIS,or Aimpoint and mount,and forget about hte BUIS for a while.BTW,if you don't know already,I'm only 14 so I don't have that much money so I have to be carefull on what I spend it on.

You are one lucky 14-year-old.  I wish my dad bought me an AR when I was your age!  Since you are so young and your funds are limited, my advice rings even truer.  Be wise with your money and get the best equipment that you can afford for your needs and that works best for you.

I just realized what my original post says.  And it's wrong.

It should say that a FF rail is NOT necessary on a carbine.


Apparently my typing comprehension sucks these days.....
