First Impressions of JMac Customs 1913 Fixed Stock Adapter for Zastava M70/M72/M90
The JMac Customs 1913 Fixed Stock Adapter for Zastava M70/M72/M90 is a simple yet ingenious solution for modernizing your Yugo/Serbian AK pattern rifle. This adapter allows you to ditch the original fixed stock and install any SIG SAUER style folding or fixed stock that utilizes the increasingly popular 1913 Picatinny rail interface. The adapter boasts a solid construction from 7075-T6 Aluminum and promises a straightforward, no-gunsmithing-required installation.
My journey to this product began with a desire to update my Zastava M70. While I appreciate the classic look of the original wood stock, I wanted to explore more modern, ergonomic options and potentially add a folding stock for easier storage and transportation. I received the adapter promptly.
Upon unboxing, I was immediately impressed with the JMac Customs adapter’s fit and finish. The black anodized aluminum looked durable and well-machined. It felt substantial without being overly heavy. Comparing it to some other AK stock adapters I’ve used in the past, this one appeared to be a step above in terms of material quality and attention to detail.
I considered other options, like adapters that used an AR-15 buffer tube interface, but I was drawn to the versatility of the 1913 rail. This system provides a wider range of stock options and the ability to easily swap between different stocks. The JMac Customs 1913 Fixed Stock Adapter for Zastava M70/M72/M90 stood out for its simple installation and its promise to correct the stock angle for improved ergonomics, which is something often overlooked. I was definitely excited to get this installed and see how it transformed my Zastava.
