This is our 1st “heat test” on Krebs AK UFM Keymod Rail. I’m waiting for weather to improve (we had another snow fall last night) and we are going to re-run this test again when it will be warmer to re-check results. We are also going to increase rounds count to 150. We are also going to apply the same testing procedure to all other future rail systems reviewed by us. Still, even taking into the account that air temperature was 30F, this rail performed very well. I think this is mainly because of the many slots in UFM rail system body, which allows to air to flow freely and cool off metal at the same time.
