The screws are to long and stop the mag. from seating. I thought I read their was supposed to be a washer which mine does not have. Is that what I need. Would a small 0 ring work? Thanks

o ring or washers.

These are what they look like, if you can't find any washers locally...

Or get a "Parts Kit" to which you'll have some spare springs you may need now, or later...

PM me with your address and I'll send you the washers from my parts kit that I didn't use.
