    I noticed a maker had float tubes (handguards) in 9.25", 9.5", and 10.5" along with the carbine and rifle lengths. My question is why have three lengths so close to each other, and what is each length meant for?
    2nd. Question The newer tubes are "slim" at 1.5" OD, do most folks really like that better than the older tubes which were fatter?

    I think those three lengths help cover or not cover the most common pistol length barrel/accessories.

    I much prefer the slim handguard to the older ones. they help give the rifle/pistol a relatively sleek profile.
    The old round free-float tubes feel ok, but make the front ends look fat to me.

    I like the slim handguards as long as they have been reasonably dehorned so that they can't double as a cheese grater. The low profile gas blocks and barrel nuts have allowed handguards to be reduced in diameter to extend slim handguards over the gas block. Instead of classics like a heavy four rail or thick aluminum tube, the slim handguards are typically skelatonized and almost always lighter. Depending on your configuration and what it is replacing, a light handguard can better balance the pistol/carbine/rifle. Uppers that have a heavy DPMS four rail, for instance, make a simple carbine significantly front heavy. In this case, replacing with a slim handguard, balances the carbine, gives more real estate for gripping and accessories, and costs you $20+ per attachment (haha).

    After a 10 year span between ARs I realized what I was missing; comfort! Immediately set about acquiring a few more with slim profile rails then revamped my first. The difference is night and day even for my XXL hands.

    What rail is that? Pic looks like "Luth AR".

    Luth-AR PALM, 9” M-LOK, $68 w/proprietary barrel nut from Optics Planet with coupon code). Very well finished and lightweight (at 9” it’s bound to be, but vastly lighter than my old RRA quad rail).
