naveed 0 Posted September 3, 2009 Report Share Posted September 3, 2009 MY MSA mag adapter is not allowing my aluminum mags to insert easily. I have taken the mag adapter off the gun. Can someone tell me what I should use to slim down the side walls. I have a dremel tool but I'm not sure which attachment to use. I tried using files but they barely scraped the paint off.

madmax4x4 68 Posted September 3, 2009 Report Share Posted September 3, 2009 (edited) Did you mill the right amount of inside? The front trunnion Edited September 3, 2009 by madmax4x4 Quote Link to post Share on other sites
naveed 0 Posted September 3, 2009 Author Report Share Posted September 3, 2009 Did you mill the right amount of inside? The front trunnion I just got my gun back from Diavolo arms. It looks like he did mill the front trunnion so I took the mag adapter off to check if it was the mag adapter. The mag doesn't slide into the mag adapter easily. I have to really push it in and struggle to press the mag release and get it out. Quote Link to post Share on other sites

protected static 19 Posted September 3, 2009 Report Share Posted September 3, 2009 What brand magazines are you using? I've found that some AR mags have wider back seams/spines than others, and that a little sandpaper to the channel that runs up the back of the adapter's magwell helped ease things along.

I'm using a 10 round c-mag and a 9 round competition aluminum mag because I live in NJ. They worked very well in my bushmaster and they are a lot thinner then the p-mag's profile. Is there something I can mark the mag with to see what areas are hitting the metal? Quote Link to post Share on other sites
