First Impressions of Midwest Industries MP5K 1913 End Plate Adaptor
The Midwest Industries MP5K 1913 End Plate Adaptor promises to unlock new levels of modularity for the iconic MP5K platform. This adaptor essentially bridges the gap between the classic roller-delayed blowback and the modern world of AR-style stocks and braces. Midwest Industries aims to provide a simple, robust, and lightweight solution for attaching 1913 Picatinny-compatible accessories to the rear of the MP5K, opening up a whole new world of customization.
For years, I’ve been searching for a reliable way to modernize my Century AP5-P pistol. The factory end cap offered limited options, and I wanted the stability and adjustability of a proper brace. The Midwest Industries MP5K 1913 End Plate Adaptor appeared to be the perfect solution.
Upon unboxing, the adaptor felt solid and well-made. The 6061 Aluminum construction instilled confidence, and the hard coat anodized finish looked durable. Compared to some cheaper, polymer options I’d seen online, this felt like a serious piece of kit. I chose it over the B&T option due to Midwest Industries reputation for quality and its anti-rotation QD sling swivel socket – a feature I knew I’d use frequently.
I was immediately excited to get this installed and see how it transformed the handling of my AP5-P. Initial impressions were positive; it felt like a quality piece, even before seeing it on the gun.
Real-World Testing: Putting Midwest Industries MP5K 1913 End Plate Adaptor to the Test
First Use Experience
I first tested the Midwest Industries MP5K 1913 End Plate Adaptor at my local outdoor shooting range. This was after a little bit of fitment “fun”, which I’ll get into later, but once installed, I was able to immediately test the functionality with a variety of braces and slings. The weather was clear and sunny, ideal for a day at the range. The adaptor allowed me to easily attach my SB Tactical SBA3 brace and test its comfort and stability while firing.
The difference was immediately noticeable. The added stability significantly improved my accuracy, and the ability to shoulder the brace (legally, of course) provided much better control. The anti-rotation QD sling swivel socket proved to be a great addition, allowing me to comfortably carry the AP5-P with a single-point sling. There was, however, the slight fitment issue requiring some filing on one of the pin holes which I had read about.
Extended Use & Reliability
After several range trips and a few training sessions spanning a few months, the Midwest Industries MP5K 1913 End Plate Adaptor has held up remarkably well. There are no signs of wear and tear on the finish or any loosening of the attachment points. It remains rock solid, even after hundreds of rounds. Cleaning is simple; a quick wipe down with a cloth and some CLP is all it takes.
Compared to my previous experiences with other end cap adaptors, this Midwest Industries product is a clear winner. It offers a much more secure and stable platform for attaching braces and stocks and the integrated QD point is a fantastic feature. I have found this to be a significant upgrade from the factory end cap.
