Mora Arms 20 Round Magazine

Overview of the Mora Arms 20-Round MP5 Magazine

The video focuses on the Mora Arms 20-round MP5 magazine and why someone might choose it over a standard 30-round option. Pricing is discussed as being around the thirty to forty dollar range, with many examples available near thirty dollars each. The shorter overall length compared to 30-round magazines is highlighted as useful for compact setups, such as a backpack gun built on an MP5 platform. The discussion centers on practical considerations for users who already run MP5-style firearms and want a more compact magazine while maintaining reliable function.

Design, Capacity Windows, and Construction

Key design features of the Mora Arms 20-round MP5 magazine are outlined. The magazine body is made of steel, and the internal follower is silver-colored metal rather than polymer, indicating consistent use of metal components. Two cutouts on the back of the magazine act as capacity windows, allowing the user to see how many rounds are loaded. The presenter notes that the parts do not appear to be downgraded or cheaply executed, and the overall construction matches what is typically expected from a steel MP5-pattern magazine in this size.

Fit and Lock-Up on MP5K

The magazine is shown installed in an MP5K-style firearm to demonstrate fitment. It locks into place, but the insertion sometimes benefits from a slight rock-and-lock motion rather than a straight push, especially when new. This behavior is compared to the feel of a standard MP5 magazine, with the difference being that the 20-round Mora Arms mag may require a bit more deliberate engagement at first. Once properly rocked into position, it seats and locks as intended, confirming compatibility with the MP5K platform.

Performance on PTR MP5-Pattern Platform

Next, the magazine is tested in a PTR MP5-pattern firearm. The same general behavior is observed: the magazine locks in securely, and a subtle rock-and-lock motion can help ensure positive engagement. The presenter exaggerates the insertion technique to make the issue visible, then notes that a firm, straight push can also seat the magazine correctly on the first attempt. Overall, the PTR platform appears to accept the Mora Arms 20-round magazine with less difficulty than some other variants, indicating solid compatibility once the user is familiar with the insertion feel.

Fitment Quirks on AP5 SD and Break-In

The AP5 SD is used to illustrate the most pronounced fitment quirks with the Mora Arms 20-round magazine. The AP5 SD is described as already being known for this type of issue with various magazines. With this platform, the user may need to apply more force or use a deliberate rock-and-lock motion to achieve full lock-up, especially when the magazine is new. The magazine’s exterior has an extra coating that feels slightly slippery at first, which contributes to the initial tightness. After firing and cycling the magazine several times, this coating wears in and the insertion becomes easier. Testing confirms that once broken in, the magazines function properly, and the issue is less noticeable on platforms like the PTR compared to the AP5 SD.

Summary and User Feedback Invitation

The video concludes by summarizing the Mora Arms 20-round MP5 magazine as a steel, metal-follower design made in Taiwan, typically priced around thirty dollars. It is presented as a compact option for MP5-pattern firearms, with some initial insertion quirks that diminish after use, particularly on the AP5 SD. Viewers who have experience with Mora Arms magazines, whether 20-round or 30-round versions, are encouraged to leave reviews and comments to help others researching these magazines. The presenter notes that additional questions may be addressed in the comments and closes by thanking viewers and mentioning plans to continue shooting with the setup.
