Out of pure boardom I decided to see how hard it was to take off my front sight base. Tap -- Tap and it was off. Now I'm interested in a FF tube.

I've never wanted to gain a bunch of weight to get FF so I didn't buy into the SIR or even the RASII. But the Daneil has always looked intersting because the barrel nut is alluminum and saves weight.

Is the KAC FF RAS barrel nut alum or steel?

Also what else differs between the two?

And don't tell me to hang on for the URX because I want to do this now.

Thats some pretty good reading NYpatriot. However, I did not see a gross weight on the Car lenght RAS FF nor did I see whether the barrel nut was constructed of aluminum or steel. If anyone can answer one of these two questions please let me know. Thanks Kris

I can't give you a gross weight, but the DD forends are definitely lighter than their KAC counterparts because the DDnut is aluminum & the KAC one is steel, like you thought. Contact Wes Grant ([url]MSTN.biz[/url]) & he may be able to get you some weight figures.

Definitely contact WES as he has the best customer service going. Either he or Paul answered for me once that the DD is 3 ozs lighter than the same size KAC for the reason that spider mentioned; DD alum nut, KAC Steel nut. Thanks.....Chad

Which begs the question... is a 3 oz. weight savings worth the peace of mind that comes from knowing that your barrel is secured to the upper receiver by a nice big chunk of steel???

The conection is only as strong as the alum. reciever threads anyway. Edit to add: Thanks for the help everyone.

I too have NEVER been able to find the weight listings for these things, after much research. It's as if the manufactures don't want you to know???

RAS 2 is lighter than my FF RAS.
Link Posted: 5/24/2003 2:07:21 PM EDT
[b]DevL --RAS 2 is lighter than my FF RAS.[/b] I just can't believe that. Are You counting the new FF Ras barrel nut but not counting the orriginal nut it replaces? Or put another way --Are you compairing the out of box weight or the weight of the compleate rifle after they are installed?
Link Posted: 5/24/2003 3:15:42 PM EDT
An installed FF RAS is heavier than the installed RAS 2 because the RAS 2 uses the standard barrel nut which is small and light. The FF RAS has a HUGE and heavy barrel nut. After installation the FF RAS is heavier. I how ever chose the FF RAS because I wanted to mount a TA11 and the RAS 2 mounts it too far back due to the bridge covering some of the front rails. The barrel nut on the FF RAS is heavier than the whole rest of the FF RAS put together. It sure makes the set up feel solid though.

OK I see. Now Daniel says its car lenght FF tube weighs 8.5oz (probably without pannels). How much weight would you estimate I'll gain (or loose) if I ditch the M4 hand guards, standard barrel nut, weld spring, C clip, and delta ring; then add the DD FF plus three Ras pannels. I really wish I had something better to do with my Saturday afternoon.

I weighed the standard carbine handguards. Single heatsheild, nut, delta ring, clip, and cap(everthing that is replaced by a freefloat tube). I came up with 6.7 oz total for the standard handguard. The M4s with the double heatshield would be a little heavier, but probably not 8.5 oz.

Thanks. That's what I was looking for.

wes I'll be ordering a DD ff as soon as I figure out what length I want. I got a wild hair to move my 16 incher's front sight base forward and put on a new gas block under the hand guard. The new Smith gas block is on order. If I can make this work I'll want a mid length. Do you stock em?

THE DANIEL DEFENSE ALUMINUM BARREL NUT IS INDEED UP TO THE TASK.

That may very well be the case. I have no doubt that Daniel Defense makes a quality product. My only point was that if the likes of Eugene Stoner & Reed Knight deem a steel barrel nut desirable, that's good enough for me. Make mine steel, thank you.

The tan one is the DD version & the OD green one the KAC.
Make mine steel, thank you.

Looks like the DD is a shade higher than the KAC. Is the top rail of the handguard the same level as a flat-top when installed?

Exactly my thoughts. Wes, can you give us professional answer?. MN

Does the DD install with a standard FF wrench, or do you need a special tool?

Wes, Does the fact that the more narrow and deep DD forend come out to equal the same rail dimensions as the FF RAS have any effect on the way it feels while firing? ie. in the end do both the KAC and DD equal the same diameter with panels on etc.? What do you think about trying out a DD forend on my 10.5" crane upper your baby sitting for me. I was leaning toward the FF RAS but this may be something fun to try out. ps. Hopein to have the paperwork for the upper back within a month....
