South Carolina-based American Tactical Inc just announced their new and improved German-made Schmeisser S60 magazine. Constructed with what ATI lists as 2K polyamide fiberglass, the newest version of the S60 is an AR/M4 compatible 60-round magazine that has been updated from the Gen II S60. The new S60W now includes both a side window to visually check round count but also has a follower designed to hold open the bolt on the last round. "Designed to shoot both .223 REM & 5.56X45MM, the Schmeisser S60 will give you an instant capacity upgrade over the standard AR mag at an affordable price for your AR carbine or pistol," said ATI in a statement.
