Hey everyone I've been looking at spacers for a while now in the marketplace and I find that noone really sells MD spacers with the copper attachment. I assume that there are a lot of people in cold areas of the country that have spacers. Does this mean that noone really uses the copper even though they say you should in cold weather? I'm wondering if I can broaden my search for spacers instead of ones solely with this copper attachment.

 

There are a lot of people here using the Copper Iso Thermal version of the spacer even if its not shown in the sig.
