usehername 0 Posted January 26, 2012 Report Share Posted January 26, 2012 (edited) I cant find a purpose for this rivet/post. On my gun, it protrudes slightly further than the front flat that houses an installed magazine. It catches and hangs up inserting the magazine most of the time, It holds nothing that I can see. To clarify, if you look into the mag well, on the back side of this rivet head is a post about 5/16 in diameter. It is slightly beveled around the end. I am wondering if this was added to put tension on the magazine. I did see a picture of a 410 without this rivet somewhere on the forum. Seems odd that it is only on the right side if it was meant to provide a squeeze for the magazine. Anyone??? Edited January 26, 2012 by usehername Quote Link to post Share on other sites
usehername 0 Posted January 26, 2012 Author Report Share Posted January 26, 2012 Update: modified one of my mags at the point of contact with this post. 100% better mag insertion. Makes absolutely no sense to me why this rivet post is here.... Quote Link to post Share on other sites
6x6pinz 4 Posted January 27, 2012 Report Share Posted January 27, 2012 took a look at mine and I think I would have tapered the rivet. Should not take much to insure reliable insertion. Quote Link to post Share on other sites
usehername 0 Posted January 27, 2012 Author Report Share Posted January 27, 2012 I am considering removing it. Look at this one owned by Cobra 76 two. Quote Link to post Share on other sites
G O B 3,516 Posted January 27, 2012 Report Share Posted January 27, 2012 Try lightly dremmeling te part of the rivet that is interfering with the mag. You only need about 1/16" of flat head on the rivet to have the full strength of it. Quote Link to post Share on other sites
PFerris 76 Posted January 27, 2012 Report Share Posted January 27, 2012 I think it supports the front of the mag. It is larger in diameter and just as long as the the side of the rcvr. I would not take a dremel to it. Maybe file it alittle it might have a bur on it. Definetly supports the mag IMO. Quote Link to post Share on other sites

usehername 0 Posted January 28, 2012 Author Report Share Posted January 28, 2012 There is no shortage of internet pics of the 410 missing that rivet. Most I found are old posts so I suppose this pin was added somewhere along the way. It has got to be a tension pin. Likely to reduce mag rattle. Seems silly to add it on one side as it causes the mag to twist slightly. All my mags are worn much more on the rear right side from this slight cocking off center. I noticed that the sgl41 has a pressed dimple near the rear of the mag well. I assume it is added for tension. It is on both sides of the receiver (a good thing) I also noticed that the front rivet/post is still there on the sgl and still only on the right side. Quote Link to post Share on other sites
