I have a Sig M400 Tread which I am slowly modifying and currently am looking to replace the stock hand guards which are junk. Even during BZO my hands got hot like there wasn't even a guard. A friend suggested the CMT HDM™ 15.0 RAIL although, I was looking at the Geissele 15" Super Modular Rail MK14 M-LOK as I swapped out the trigger with a Geissele. Just my OCD. What attracts me to the CMT is they are American made in Tennessee and are a veteran owned company. Any knowledgable opinions are welcome as I am old school and basically utilized what was issued to me. We did do builds in my day. I will also be adding illumination so if you have a thought on that please feel free. Thank you in advance!
