I have a middy on the way from bcm. I plan on getting a DD omega 9 for it. But kind of like the look of the 12 rail. (yes it's DI) I'm just looking to get your opinions and see if the extra rail after the FSB is worthless or actually worth it and if you think I should opt for it.

So what say you?

And do you guys prefer the extra rail on it or even use it for the guys who have it? Or is it ok to go with out.

Wither way I'm going to be happy because I came from a carbine so I'll have way more rail space than before.

I personally prefer longer rails, the difference in weight between the 9 and 12 is small so it's worth it to me.

If I was going to go with the four rail look, I would definitely go with the 12".
Though my middy just has the round handguards. I kind of like simple ARs, thinking about putting together a "pimped out" one soon though.

Are you ordering the BCM middy with the rail already installed or are you buying them separately?
If separately, does the upper already have a traditional FSB on it?

Separately and yea it does. I like fixed iron sight DI guns. Not sold on pistons yet.

I plan on getting the plastic handguard for a little while until I'm sure exactly what rail option I want.

Not to bust your bubble, but I'm pretty confident that nobody makes a FSP rail like your 2nd picture for a midlength system, only the carbine length system.

If you want to go with the 12", you'll need either a rail-mounted front sight, or go with a dissipator style.

Might wanna take a look at this.

ETA: HKDave beat me to it!

The closest I've seen is something like the FSPM from Daniel Defense:

Do you need the extra rail space?
Hell, do you need the rail at all?

If you need it/will use it, then by all means go with the longer rail!
If not, keep it practical and go with the shorter one!

Though, for style points alone, I do like the look of the longer rails a bit more, but on other hand I prefer function over form usually.

I don't know about you, but a carbine length handguard is pretty much useless, even for a 5'8" guy like me- And while the 9" is a little better (because it allows you to keep a FSB) a 10"-12" is much more useful/functional by allowing a longer grip, especially for us that shoot NTCH.

Do you ever put your thumb over the top when firing?

Here's my 12" rail. I do like the extra real estate which allows me to grip farther forward.

I'm also expecting an upper with a 10" DD lite rail.

Nose to charging handle. That's what I do, but I don't try to touch the end of my barrel while doing it:p

Nose To Charging Handle

AHHH...
well thats the way I shoot too, but Im only 5'7" with stubby arms, so maybe its a none-issue for me, at least with the stock extended I can still get my nose to the ch and keep my support hand right on the FSB without bending it too much so I can go thumb over bore and look all magpuly/3gun shooter while I shoot from a bench :D

The extra rail space is good for sight radius.
If you're running a fixed sight, then that is a non-issue.

So what else is it good for?
More stable platform for a laser or tactical light. Ya, a couple of inches does make a difference in the stability of the laser dot.

AFG/VFG? Not helpful since your weak-hand grasp is going to be behind even a carbine FSB.

Bipod? Ya... very helpful there. Again, more stable platform in making a longer "wheelbase" between the bipod and your shoulder.

Yea the carbine doesnt allow me to lock out my arm like I like to when doing the carbine class style shooting. Planning on taking a class soon.

And I dont really need the rail Im not into lights and laser just yet other than cool points.. But I do have a AFG I want to use maybe get the stubby magul VG. Other than that no I just like the look and the option if I ever decide to get tacticool stuff.

Do you ever put your thumb over the top when firing?

Yes. 90% of why I wanted the middy over my carbine. other 10 was sight radius.

Yup.

And explain please.

I love that look but thats either a piston of chopped FSB right?

It's a low profile DD gas block that sits inside the rail. The front sight is a Troy folding front sight.

How much was that?

You can get a low pro gas block for under $100 easy. You knock off original FSB, replace with that and get the rail length of your choice with no opening for FSB.

I asked abput the thumb thing because if you want to mount asscesories up fron, the longer one woul allow you to put accessories in front of yoir hand on both sides, but it looks like you moving in a new direction anyway.

If you have a 14.5, you might have to unweld you pinned muzzle device, it will probably be destroyed.

09-24-2011, 7:24 PM
no I'm getting a 16". Dont see the 14.5 being worth the trouble.

just remember no one makes a rail for the midlength like the 2nd picture you posted in your 1st post, that allows you to keep the standard FSB.

Yea I think im going with the omega 9 for not then later get a 12" and get the low pro gas block or cut it. Ive seen some guys have the FSB cut to fit under.

Not true. The DD lite 12.0 FSPM is made for the middy.

It's still not the same style as the omega x 12.0 fsp

correct, but it does not have rails at the 12 o'clock position in front of the FSB, like his 2nd picture shows.

Here's mine. BCM midlength upper,KAC flip ups, TA31RCO, 12" larue rail, LMT complete lower. I really like the 12" rail. I shoot positions with it and it's very comfortable.
