We did some extreme low light rifle runs. However, we had some issues with the rifle failing to fire. Was disappointing to say the least. But this is a prime example of why you ensure your firearms are functioning correctly. This was a last minute build where we took a LumaShark upper with flashlights build in to the hand guard and put it on a high end competition lower without testing. The lower is picky as it has a 2 stage 2.5 pound trigger from Elftmen tactical. It seems that trigger didn't like the BCG and firing pin of the LumaShark. Our next match will be using a Tavor X95 bullPup.
