John Farnam's tip on rail-covers

Below is an excellent example: John’s thoughts on rail covers. Here’s the full text of that tip. Thanks John, for letting us share it with P1 Members.
The most common accessory-mounting system for serious rifles is currently the “Picatinny Rail,” which has, by now, all but superceded the similar “Weaver Rail.”
After the 2004 SHOT Show, I “railed against rails,” seeing so many rifles with maladroit accessories heaped upon them to the point that it was difficult to actually see the rifle itself under all that junk!
In the interim, I’ve been compelled to admit I was wrong. Like anything else, rails can be misused, as noted above, but, for modern, serious rifles, they have turned out to be a great boon to mankind!
Top, side, and bottom Picatinny forend-rails provide a genuinely secure platform for mounting optics, weaponlights, and lasers, the three most applicative accessories for serious rifles. Heretofore, many accessories were glued, screwed, and pinned to guns. None of these attachment methods were sufficiently durable for serious weapons. Conversely, Picatinny rails are not only durable, but they are also positively “repeatable,” so that optics can go on, be subsequently sighted in, then come off and go back on, all with no necessity for re-zeroing.
However, one pesky downside lingers on:
Forend rails on the side and bottom will scuff hands, particularly in cold weather. They also snag on fabric.
One solution has been rubber “rail-covers,” but, until recently, they have been excessively bulky and difficult to adjust with regard to length.
Now, Surefire is marketing its skeletonized “Z70" rail covers. They look like a rubber ladder, and fit onto Picatinny rails, filling in the slots, but adding no bulk! They come in five-and-a-half-inch lengths, but can be easily cut to fit any unoccupied portion of rail.
However, heat is still an issue, although railed forends are typically shielded. So, for maximum cooling, it is best to leave as much rail exposed and uncovered as possible.
The result is a good, non-snag gripping surface that doesn’t scuff hands.
I have them on all my railed rifles.
