I have a BCM Middie upper on the way and I can't decide. I know the install will be harder but I think I can manage.

I'm just not sure what to get, or if these wille ven work on a Middie.

Daniel Defense Omega 9.0

The only FF choice as far as I am concerned for anyone that can turn a screw. And one that doesn't look funky like the VLTOR or the KAC.

K.I.S.S.


The traditional AR looks best IMHO

I went Omega because i like to run a VFG and a light. If thats not your cup of tea +1 on the K.I.S.S.

excuse my ignorance, but what's the difference between free float and non free float? Also, what's the difference in installation? Do free float and non free float require different tools? Special tools?

I thought you had to remove the barrel nut and sight for Free Floats, but it appears you do not need to with that Omega. It is 10 ounces, but I think it looks nice.

I was thinking at least a light, and then maybe a VFG, but maybe KISS is the right method...I dunno, you only live once :)

Also what about something simple like this?

You can always just put a single rail on the bottom of your hand guard and attach a VFG and a light.

But will you really use the light? And will the VFG make you a better shooter, really? Spend the money on ammo and range time. A lot of instructors have told me that VFG's are okay, but a solid grip on the standard hand guard will be the most effective at keep your barrel from rising and keeping your sight on target. After trying it both ways at the range and through movement exercises, I found that it was true. Griping the standard hand guard seemed more natural to me. After that I decided to K.I.S.S. and learn to use my rifle as it was designed. But if tac'ing it out is what you wanna do, that's cool too.

How does the Omega 9.0 feel mounted? Solid?

What about the standard hand Gaurd?

I decided to free float mostly because I hate seeing that ugly gas block, it is just plain ugly and the front sight is so outdated and in the way. I much prefered the look and functionality of the free float rail/tube over the gas block with a folding sight.

If you can stand the front sight gas block (looks or functionality) or don't care about the handguards sitting over the gas block, I would suggesting going with non free float handguards. Chances are you won't see the difference in accuracy and the FF handguards will just add more money and weight to your rifle.

+1 on the Omega. They are solid, solid, solid, and super-easy to install. The best part is the slim profile.

not sure if OP had the BCM with the front A2 sight post. if he did, it is easy to remove the front sight post/gas block himself? or does he need a gunsmith to put a low profile gas block so the free float hand guards can cover it?

I have a CASV-M on one of my builds and am very happy with it. Installation was a breeze and I love the ability to customize rail position (normal railed systems are like cheese graters on my hand). The only issue I have is that there is no ability to co-witness the BUIS thru an Eotech

I have the flip up sight for the CASV-M but don't use it as I have a front sight post. I prefer the sight post for its durability over a fold up. I'll probably end up selling the front sight in Marketplace shortly.

Yes the BCM should have the front A2 sight.

It appears the Omega 9 Free float is a 2-piece so no dissasembaly is required.
But my friend has some shop stuff and I'mpretty sure he could help if it was required anyways. I was thinking to remove the front post anyways to replace with a Troy Flip up fropnt and BUIS, it just seemed nicer, but if stock is better I will leave it with that. I'm planning on an EOtech eventualy which is what I plan to put on there.

I have the MI free float rail and I love it. Super easy installation with no need to remove front site post.

BTW those prices are aweful. Whatever you buy please find another website like Riflegear.com to purchase from. I feel dirty just looking at their prices. :nono:

+1, i have the DD omega 9.0 on my rifle and its a solid rail and not hard to install, took only a few minutes, this is the easiest way to go if you free float.

My advice is that if you want to try out a rail then go for it, you can always put some plastic handguards on later. The Omega rail is pretty cool for that reason, you can easily swap it out if you want.

You don't need "shop stuff" to remove the A2 front sight base, there are full instructions here: http://www.ar15.com/forums/topic.html?b=3&f=4&t=226782

However if you remove your A2 FSB you'll need to replace it with a gas block of some kind, either a low-profile or one with a folding front sight built in like a PRI or YHM.

Big yes on the D.D. Omega system. Two of my rifles have the Omega 7.0 and they are great; easy to install.

Does it require me to replace the gas block or not? It's going on a Middie upper not a Carbine, if that matters. hard for me to visualize without having the upper lower or anything in my possession yet.

I didn't like the standard A2 FSB, and liked the look of a rifle length rail on my 16" middie barrel. I also use a CAA flip up VFG, and did not want to worry about any pressure I was exerting on the grip affecting the accuracy.
This is what it came out like using a YHM free float, and Samson lpgb:

I am very happy with the results, and with a few tools it was easy to install.

Another vote for the Omega! Super easy to install and I love the oval shape it has... Much easier to grip... :thumbsup:

So I went ahead and picked up an omega 9 before they get impossible to find as well...

Theres a chinease knockoff going for alot less...
As well as many others that appear similar in style. Like the YHM and this one looked cheap on ebay.

I hope the Omega 9 was really worth the extra cash.

Thanks for everyones help and that YHM sure looks nice as well! And I agree on the rifle length looking pretty sweet. Since this is my first build I didn't want to complicate things so I'm going to keep the A2 front sight for now. I can always change it later right? Or possibly start building on my second lower. If I want to go with the folding front sight in the future I can still do that with the Omega 9 or is the full rifle length required?

So if i were to go with a 14.5" mid barrel... what size rail should i go for?

My plan is to get a different gas block and use BUIS's instead of the stock one.

Also, I would need to order the barrel without an permanent flash hider and have that permanently attached after i get everything mounted up correct?

You can get any length you want for the railed forearm as long as the gas block is low enough to fit under it. Personally I like the JP VTAC system. But it's not light.

You order uppers with the FH already permattached.

How much does it typically cost to have a FH pemattached if i ordered a barrel?

I have midlength Midwest free-floats on my carbine. Does it shoot any better? Who cares?!? It looks fantastic!

Ok So I got the Omega Rail but I don't understand how to install it. It says no modifications needed but it would appear I need to dremel off the delta ring. Howerver the directions say to retract it, but it does not seem to fit my BCM upper?

N/M I got it sweet, it didn't look like it was going to fit really gotta compress that delta ring!

Ok I got this thing installed, but how on earth do you get teh Santoprene rail covers over the rails?

Edit: Got it they just pop on with some force
