Long story short I decided owning body armor as a civilian wasn't as LARPy as I may have thought as recently as even a year ago. Anyway, I've acquired plates and a carrier and am realizing how much it affects mounting my rifle. The plates are 10X12 single curve shooters cut and I'm running the carrier slick. I believe I'm wearing it correctly, high on the back and just below my jugular notch. When not wearing the carrier I usually mount the rifle feet squared up with the buttstock squarely in my pectoral muscle which keeps my head directly in line with the sighting system. With the armor I have to mount way out on my shoulder which makes me have to cock my head to even see the sights. I tried shortening length of pull doesn't seem to help. Stranger still is I don't have nearly the same issue with the Beretta 1301 as I do with the AR. I still have to make a slight adjustment but not nearly as much as I do with the AR. Any tricks or tips?
