Armalite AR10A4CBF

[Geno]

I recently picked up an Armalite AR10 carbine used. Good condition. Found it to be a 10A4CBF not the economy defender. Score! Now I want to put a free float fore end with a 12 o clock pic rail and thin in grip. I think that means a keymod type. Any ideas as to quality or economy of available fore ends?

[Geno]

I may not really "need" free floated?! 16 inch barrel, just lightweight.?!

[Whootsinator]

You don't necessarily need a keymod rail, but I don't think there's any reason to have a non-free floating rail today.

[Geno]

It would appear that free floated rails are limited for Armalite brand Gen II carbines. I wonder if a 10 inch shortened to 8 inches would be feasible? I figure as long as the barrel nut attachment is complete, then the length would be arbitrary. Am I off base here?

Good luck on removing the factory tightened barrel nut
I had to remove one on WMan AR -10 and I called the factory, they just wrench them off and replace with a new one.

In that case, the cheese grater direct replacements may be the way to go for this " project " HaHa

Pulled mine off with no problem.

Another gratuitous picture.

The float tube nut required a BFPP to remove. About two foot long for leverage.

And skinny cranky arms pushing on it

What I used to remove my AR-10's barrel nut and install the new (Armalite's) barrel nut for their free float tube.

My AR-10 with the free float tube

WLJ, what length barrel is that? Also, is that a rifle length barrel? Did you remove the gasblock to install the tube first?

20 inch and yes to the gas block question.
Had 16" carbine AR-10 but sold it. The RFB replaced it.

BTW: I've since replace the buttstock shown in the picture with the reg factory buttstock

The nut did not have holes in it for a wrench.

The one Cranky did for me was an old AR-10A4.

Crush, kill, mangle, maim, destroy.
