Short barrel, tight space, clean solution. In this video, I mount a Streamlight TLR-1 HL on my Mossberg 590A1 14″ using the CDM MTRS-12 clamp. I unbox the light, show the mount, install everything step-by-step, and do a quick beam/fit check. If you’ve been hunting for a compact, solid way to run a light on the 14″ Mossberg 590A1, this setup is a beauty, low profile, tucked in, and rock-steady.
