I have an LMT LM8 MWS. I have the 16” CL barrel and a 20” Stainless 6.5CM. Great gun. With or without a can it always works and is accurate. There is a new m-lok chassis out. Only thing I would change is run one of the light weight barrels to save weight. Seriously considering SBRing it to run a 13” with my can.
