LR - what is the wood furniture in your first post. On that pistol
You can put wood triangle hanguards over a DCM free float tube with mods, but it will be heavy.
The little carbine is from Battle Arms Development. They sell the wood panel accessories for their handguards.

Give me a round or octagonal free float with a continuous top rail and capability to attach smaller sections when and where I want them. I despise quad rails. I like the triangular handguard for retro rifles. Just feels good.

While not a free float affair, they are very comfortable, transfer little heat and are affordable. I think what I most like about it is how it reminds me of how comfortable the original A1 hand guard was. The wider bottom lays naturally in the palm, and also provides what I consider to be a more stable contact point, when laying it on sand bags or other rests.
Had to chime in on this old thread --- as I also have a positive opinion of the Magpul MOE handguards. Very comfortable to hold and lock in very solid. I wouldn't say they remind me of an A1 HG though, which IMHO is too fat at the rear and tapers to too small at the front. I acquired an old surplus A1 upper many years ago and couldn't change its HG fast enough to an A2 type. I just couldn't stand the feel of that taper.
No, the MOE, to me, feels much more like a FAL HG, which has that interesting and comfortable triangular x-section but thankfully does not taper:

EDIT: And in case it hasn't been mentioned, here is PRI's CF triangle handguard. I like this design also. Don't know if one/style has been mentioned in this thread yet:
Don't overlook Midwest Industries hand guards. They have a very nice selection of well made MLOK guards from ultra light wight to ultra slim. I think my favorite is the slim MLOK as it feels really good in the hand.
- Made in the US
- Anti-Rotation tabs
- Barrel nut that doesn't require timing for gas tube install
- All kits come with barrel wrench and plastic MLOK rail section
- QD sling sockets
- Nice selection of weights and lengths
I have no affiliation with MI, I just think they're stuff is solid.
I also like "some" of the Strike Industries rails and have one of their rails on my Grendel and another 20" 556 rifle.

When it comes to handguards, I have favorites for different settings and configurations. All of this is of course IMHO, and we all have our preferences.
For 20" National match, I quite like the classic A2 plastic handguards, over a free float tube.
For 20" AR Tactical, where I will run a bipod (and where Grendel really shines in that 600 yard course), I like a more typical modern aluminum handguard, free floated of course.
For M4 style level high speed rapid fire, at a sustained high rate of fire, I've learned the hard way that the nifty bare aluminum handguards become too hot to hold onto after about the 3rd magazine. And for anything select fire or othewise intended to be able to do 90 rounds of fire in one or 2 minutes, a heat shield and plastic is the way to go. The Magpul line is excellent, for the reasons already stated.
For general purpose patrol-rifle M4, my own bias these days is for a very light weight comfortable build, that's easy to maintain. For me, running something like a skinny FAXON Gunner Profile, or Pencil profile. When made here in modern times with our modern high QC metalurgy, machining, finish, and stress relieving, , I've personally found skinny barrels can deliver excellent accuracy and excellent sustained accuracy even when hot. Which was something not to be expected, even 10 years go. So to that end, with a more KISS but with features (ha, no contradictions there), on a patrol rifle general purpose build, I've grown to really like this particuar handguard, from PSA of all places.
I particularly like this unit because:
-Extremely light weight.
-Middy length is plenty long for the longest I typically hold my rifle (I've never been one to reach out past the gas block on how I use my gear, personally). But longer than the 7" carbine length, which really is too small and short.
-Yet it stops just short of the gas-block, which allows access to maintenance of the block. With the more common adjustable blocks these days, they tend to sieze up adjustability, unless stroked or accessed. And sometimes one wants to pull off the gas-block, which now can be done without screwing with removing the handguard. And just a personal preference, but I actually like my gas block exposed.
-Has machined in QD points on both sides, with ratchet components even. Meaning closer to KISS, since I don't have to add an addition mass of a sling addition point, the holes are already there. I like this.
-Diameter. I like the smooth and skinny surface and diameter, and find it very comfortable and prefered for my particular hands.
-Free float. It comes with a barrel nut, and attaches only to the barrel nut.
-Stable generation. PSA went through seveal steps of generation with securing systems, with earlier ones rotating when hot, etc. This one has little ears that revent rotation, and a lock point to prevent sliding back and forth. Simple, yet secure.
-Expandable, if I want more rail, it's very easy to M-Lock add particularly what I want, and only add that. I don't care for the look, weight, or feel of unutilized rail-space, personally.
-Value - this is actually a high quality well machined and well finished handguard, that is sold at PSA prices.
Here is what it looks like on my current patrol rifle configuration, which is my favorite overall general 16" M4 .223. On this one, I run a low-blast but still effective BCM break, that I also just love. I run the same handguard on my 14.5" pin and weld Grendel. (gun in background is an MDRx. I like bullpups, I like 6.5, that's the only 6.5 bullpup ya can get)
