The thing is a POS , after a couple of taps the edge flared out and I didn't notice, it started to push out on my spikes lower. After I saw that it was flared out I backed it out and put the original roll pin that came on my spikes in there. The spikes roll pin went in as smooth as butter. I am pretty pissed that my new lower is damaged. . Side by side of the 2 pins you can tell the magpul one is garbage but had confidence in magpul cause my moe stock and grip were great. Anyone else have problems? I used the correct punch but what it looks like happend is the edges gave out flaring out the pin at the end.
