I ordered a SAI 5 round flush fitting mag using my Loaded coupon several months ago but hadn't really tried it til a few weeks ago at the range. It won't snap into place with the bolt closed when loaded with 5 rounds. I have tried every which way. Locks right in with 4 rounds. I did notice that when fully loaded the last (fifth) round is on the opposite side compared to a fully loaded 10 or 20 round mag. I'm thinking this is why it doesn't work fully loaded. I called Springfield and asked them what's up with that. They said I should load the mag with the bolt locked back. Yes, this does work but then the bolt snags a live round when it closes. I can't push down on the top round and slowly close the bolt either, it grabs a round no matter what. I always load my mags with the bolt closed and just work the action to chamber a round. I would like to carry a loaded 5 round mag while deer hunting and not always have a round chambered. Am I overlooking something? Thanks for the help!
