Owner gulf coast firearms - Lancer Systems L5AWM AR-15 .223 Rem/.300 Blackout/5.56x45mm NATO 30 Round Detachable Rifle Magazine

These magazines have function flawlessly. They are great when you have the deed for an additional type of magazine to differentiate 300 blackout from 556 because the stipple you can identify them and no light situation and I have not had any problems with them functioning anyway they’re also a good value.
