The complaint lodged there was first started with this post
Anyone shot one of these (or any upper with the Centurion CMR Mlok rail) enough to comment on heat from the gas block? One reason I like having a rail with 45 degree slots is that it allows more protection from the gas block when using rail covers, but the CMR rail has large vent holes in that area.
the discussion proceeded, and I commented that my favorite handguard was always the "OG M4" handguard from Daniel Defense, which they don't make anymore. The dimensions of which were
2.43 tall, 1.94 wide, 1.45 ID
DD does make a handguard that they call the "M4", but it's really just the old Lite Rail III with a new name (https://danieldefense.com/rail-systems/ddm4-rail-tm.html). Dimensions of which are similar, but in 2018 it's hard to justify a ~$400 handguard.
2.16 tall, 1.90 wide, 1.08 ID
Anyone that's known me for awhile shouldn't be surprised to know that I had a chart comparing handguards (https://docs.google.com/spreadsheets/d/1qHX2hdnP6UOWTs7fCbpqvKYL6WmPakx2ZgxTyKLzJOo/edit?usp=sharing) from a few years ago (prior to the Keymod/Mlok craze). there are a few of the keymod and mlok handguards I added there but nowhere near the number that are available today.
My preferred setup for a "quad rail" is to use:
short foregrip like the Tango Down Stubby (https://tangodown.com/tangodown-vertical-fore-grip-stubby-bgv-mk46k/) (anyone else remember cutting down one of their OG grips before they made the stubby?) or Magpul RVG (https://www.magpul.com/products/rvg).
Larue Index Clips (https://www.larue.com/products/indexclips-72-piece-set/) where my hand normally touches the handguard
Magpul Ladder Panels (https://www.magpul.com/products/ladder-rail-panel) on most of the other exposed slots
I like the plastic to be tan not because:tactical but because:Florida and a gun that sits in the hot sun is no fun to shoot.
I know that someone at this point is wondering why go to the trouble of getting all those slots only to cover them up. I'm sure to some extent it's simply because it's what I'm familiar with because it was the new hotness back when I was shooting 5-10k rounds a year. But I also believe that this combination gives me the best of both worlds in terms of comfort at the contact points, control of the forend, and dissipation of heat through the natural heat-sink ability of a picatinny rail.
anyone else still prefer the "quad rail" handguards?
