AR 10 SQUARE free floating hand guards was created by a Guest
I want a free floating round cornered square alloy hand guard for my DPMS built Remington R25 shorty project. Unfortunately this particular R25 is one of the newer models with the lower rail height on the upper. This rail height does NOT interface with the old DPMS rail height, for which Badger Ordnance used to make a very nice square rail.

SO,
I guess I have to build my own AR 10 square handguard. I have been thinking about simply machining the outer threads on the DPMS free float barrel nut just a tiny bit deeper, and almost all the way to the back of the nut. That way, I get greatly improved bearing surface and strength at this critical connection. Then a simple round solid alloy block, with the inside milled out to accept the square alloy tubing, a few bolts, some loctite, a few rails, and VOILA ... I've got what I want.

I have both 2" and 1 1/2" alloy tubing available right now. 2" round cornered alloy tubing feels too fat in my hand, and unless I mount the tubing OFF CENTER, offset downwards, with the gas tube protruding through to the underside of the top rail, it would be much too high to co-witness with the original upper receiver rail. I like the feel of smaller and lighter weight 1 1/2" round cornered square tubing, and this size would give a better front rail match, but this size tubing [ 1.25" ID ] gets tight. Ideally 1 3/4" tubing with .010" wall thickness would work best but I can't find anything like that locally in small pieces.

Any feed back on this concept would be appreciated, especially from any one who has BTDT with making their own AR 10 handguards.
thanks

I have an ArmaLite AR-10(T) with the Badger Ordinance free float tube. I love it! Back when I bought it there was not much available in the realm of aftermarket free float tubes. Now there are a ton of options out there.

I really like that it gives the option to add small side rail sections though I have never had the need for this.

Too bad they have not produced one for the R25 yet.
