I wanted some of Magpul's tactile lock plates to differentiate between supers and subs for my .300 Blackout. I only needed a few and magpul wants $20 for 5 of each type, so I designed my own.
I use the single bump for supers and double bump for subs. But you can use them for any caliber that fits standard Pmags if you have various ammo types or calibers.
These work with Gen 2 and Gen 3 Pmags.
Print flat on either top or bottom, supports everywhere. I printed with 6 perimeters as well as tops and bottoms. PLA should be fine.
