Comparison Chart of FF Rail Dimensions

[rob_s]

Chartman strikes again. Work in progress. Numbers on the right-hand side are weighs in oz.

You are the man. If I could be anyone, it would be you, or Wilt Chamberlain, but most likely you.

Seriously, I was hoping someone would do this.

And it looks like I'll be going with DD for more my rails.

i'd be curious to see how much the DD rails would weigh with a steel barrel nut... didn't they offer that a few years ago?

Well, considering Wilt is dead, that is not much of a compliment

Looking good VisorMan!

According to Wilt's book, he was the ultimate pipe layer!

Great job on the chart(s) Rob. Your info is always logical and thorough. I have DD lite rails on both ARs and they are the highest quality. Money well spent.

Sorry, my previous comment was a little homage to "Evan Almighty". But that's beside the point. Rob, I think you may have missed your calling.

Sweet. Someone who loves excel charts as much as me...

Perhaps an additional column denoting Barrel Nut Material? I'm deciding on a build right now and I'd be interested to see what the numbers come out to be for the 12" VIS and the 12" SWS rails.

Well done. How about adding round FF tubes (VTAC, PRI) and then IDing the number of rail slots available with their add-on rail sections?

No Mk18 RIS II rails?

Weight is 14.5ozs
Length is 9.5"
Width is 2.2"
Mil-Spec Flat Dark Earth Type II Anodizing

It's the strongest rail DD makes. It's made from a solid piece of aluminum not an extrusion. It mounts similarly to the Lite Rail but doesn't require the gas tube to go through a portion like the Lite Rail when mounting the rail over a low-profile gas block. I 'shaved' my FSB to fit under my Mk18 rail and installed the gas block and gas tube before installing the top rail. Bottom rail is held on with 4 side screws like the Omega rail.

Here's mine mounted on my 12.5" SBR.

Just make certain you note its Count Chocula milk color on the chart. Yes, I am jealous and so have to make comments about the color of the FF
