Looking for some ideas here. I put together a 6.8 SPC AR to use for deer and coyote here in Va. This rifle has an non-railed aluminum tube forend on it. The problem is in the 20-30 deg. temps in the winter the tube gets colder than a well diggers ass. I wrapped it in 550 cord but I am looking for something a little more permanant to insulate it a little.Iprobably should have put a Hogue rubber coated tube on in but I had the YHM tube already.....thanks
