    Those panels helped a lot. Although they got hot, I wasn't wearing gloves and found the heat to be very manageable. I used an infrared thermometer and after I finished the last magazine measured the temp of the rail panel at 145 degrees at the point where I gripped it. The barrel was 310 degrees just in front of the rail.
    Great info, thanks! I really appreciate you taking the time to get legitimate temperature readings. I don't suppose you've ever taken readings on the DD rail it replaced under similar conditions, have you?

    One odd thing I noticed is that with steel barrels mine heated up more but when running it on stainless barrels it doesn't get as hot. I can't imagine it's the material so it must be the profiles or something but I don't know. I didn't have equipment on hand to record any real world measurements so this is subjective at best.
    Interesting. Are the profiles the same/similar or different? Is your rate of fire the same, or do you shoot the stainless barrels at a slower pace? I could see how you might shoot a stainless barrel less or slower at a range if it was more of a precision set up compared to your steel barreled guns.


    I was looking at NSRs online yesterday and one site I found them in stock at mentioned that an internal heat shield was supposedly in the works that would attach between the barrel and the NSR somehow without using any of the keymod holes. They failed to mention who was developing said device, or when it would be available, so I'm a little skeptical. But it did get the gears in my head turning... there's got to be some way to funnel at least some of that heat away from the rail and out the front...

    No, never checked the DD Lite. As I was driving home, I was thinking I should have pulled the panels off and checked the bare rail temp too, for comparison

    This thread is a wealth of knowledge on the NSR. From some of the questions it seems like some heve yet to find it via search, or taken the time to wade through it all. IIRC, some posts discuss a DIY heat shield conversion.

    Thanks for the link. Any idea what page the heat shield is discussed on? 60 pages is a lot to wade through... I just spent half an hour reading and made it to page 8... tired eyes.

    Noveske NSR FF tube questions.

    While I think Cold reports some thoughts using the heat shield, I don't think there is any concrete info on it as it is not available yet.
