I've had the standard mil-spec Nitride coated can pin that originally came with my M&P15 and after a 1000rnds it's not spent but it definitely has some wear. So I figured since I was replacing 90% of the gun that a upgraded cam pin was in the cards. I looked at the dommed Lantac pin and the POF Roller pin but coming across the V Seven enhanced pin I decided to go with it since it's about half the price. This cam pin was professionally carved, cut & coated. Perfectly made and the quality is very evident. I really like the fact that it's a strong steel w/ nitride coating and how they managed to curve the corners of the pin itself. Now I will admit that this pin may make the cycling smoother but as far as I could tell it may have had a small effect on the BCGs smoothness. The only con was that the pins corners are shown as a nice smooth curve in all the pictures but when I got mine home and inspected it, I found that the pin I received wasn't as the photos showed but actually have some slight edges around the curve instead of one smooth curve. Now this isn't a deal breaker or even causes any negative effects but this is still something to think about. Highly recommended and a true piece of American art.
