One of the greatest downfalls of the HK USC 45 factory offering is the 10 round magazines. It doesn’t offer the utility and flexibility of many other carbines on the market.
Our magazine offers double the capacity of the factory magazine at 20 rounds. Specifically designed to work with our USC Lower Conversion, this magazine is ready to feed 45 ACP over and over. This magazine is a double stack design, which allows for a smaller footprint compared to other 20 round magazine offerings for the USC.
The magazine body, floor plate, and followers are made in the USA and are 18 USC 922R Compliant. The internal springs are factory HK springs.
