Hello from Maine,

I have a 20" barrelled "classic" AR15. I like the look of the "rifle legnth tubes" on the 16" barrels, so I would like one that is long enough to almost cover a 20" barrel. Maybe 18". Does one exist?

Thank you,
Craig

The longest I've heard of is the DD 13.5" or the Troy 13.5"

DPMS and Olympic have made 16" float tubes in the past but I don't know if you'll be able to find one anywhere.

Here's the Oly tube on a 20" barrel:

That's a great looking rig you have there.

Here is mine:

I don't have an FF tube in front of me so I don't know how complicated they are - do you think it's something I could have my machinist whip up real easy like?

I was thinking of a smooth tube with "timing" and a sling stud on the bottom. Not a very tall order I suppose...

Thanks,
Craig

p.s. Is that a thread protector on your muzzle? I was thinkign of getting one fo those or an AK74 style brake (the most efficient design for 33 years!). The muzzle jump with the flash supressor is a drag when using a scope.

OK, I e-mailed a bunch of companies looking for a long tube, so far Oly Arms is the only one that knows of any and it's out of stock:

Craig, The longest free-float tube we make is 12-1/2" long. We do offer a free-float FIRSH quad-rail forearm which is 16-1/4" long. This is our Part No. F8LCR, at $155; I fear it is currently out of stock. I have not heard a projected resupply date. Thanks-- Lee

This company may have it in stock, they have instructions for it:

There are not any available off-the-shelf that I am aware of.
However, there are a couple companies that WILL do them.
