This product is great, but I gave it 4 bullets for this reason.
For one, DPMS has mass produced these popular items so much, that when mine came in the mail, it was a warped dud. So when I got my new one almost a week later, I put it in. It works just like its suppose to, but not really without being oiled (duh). And with my hydrolic buffer, its a really, REALLY tight fit. This item deffinetely saves your fingertips!|
