after having the lower sitting on the shelf for a year i noticed the mag release lever starting to bow from spring tension . the springs i use are from the home depot multi spring pack (#13554) so it may be a tad more stout than needed to be but either way this is a fix for myself and just uploading the file as backup. i have tons of these 4mm hardened steel rods i salvaged from a factory conveyer so i cut to size hammered into this with epoxy and will let sit again. hopefully it stops the bowing.
