Will this fit an aero precision M5E1 lower? Expert Answer

Good Catch by alexeme, Verified Owner, August 30, 2024
Replaced my original magazine catch with this product because my mag kept falling out the weapon every time i shot it. Since replacement I’ve had no issues and I’m about 300 rounds in. So far so good.
