Tried it only while sighting my BUIS, about 30 shots total (sighting and finishing the mag). I had just shot about 200 rounds over 3 hours in a class on a different carbine. Definitely felt different, could feel the buffer moving back and forth. Kick seemed flatter, but I was being distracted by the buffer. Looking forward to trying it more in the near future.
BTW, Sprinco sells the machine gunner lube in larger bottles; I grabbed 1 tiny bottle for each BCM hand grip and a 4 oz bottle to top them off.
