The Zastava Arms USA M72 RPK is a semi-automatic rifle chambered in 7.62x39mm, built on the RPK pattern with a 1.5mm bulged trunnion receiver for added structural strength. The 21.5-inch ribbed barrel with cooling fins is designed to handle extended shooting sessions without the heat buildup that affects consistency.

Detailed Features: 

The factory bipod is included and mounts directly without modification. The left-side optic rail accepts standard AK-pattern scopes and red dots. The battle-worn walnut stock is functional and gives the rifle its classic RPK look. The blued finish is traditional; it requires reasonable maintenance in wet or humid conditions.

Discussion on the M72 RPK centers mostly on its build quality and the RPK's role in AK history. Owners consistently note that Zastava produces a solid firearm. The stamped receiver and overall construction hold up to hard use.

Accuracy gets mixed but generally positive reviews. At close to medium range the 7.62x39mm performs well, though shooters used to precision bolt guns note it is not a long-range platform. Recoil in rapid fire is manageable given the weight and gas-operated system, though the weight itself comes up regularly. The rifle is heavy, and that affects how practical it is for extended carry.

The factory bipod and optic rail are appreciated for adding functionality without requiring aftermarket work. Some users interested in more modern features (lighter builds, modular furniture, or easier modification) find the M72's traditional construction limiting by comparison. Price is occasionally raised as a sticking point. For AK enthusiasts or collectors drawn to the RPK lineage, the rifle is well-regarded; for buyers prioritizing light weight or modern ergonomics, the trade-offs are worth understanding upfront.

Build quality is the defining trait here. This is among the best work I have seen from Zastava, and the overall quality makes this M72 feel like a particularly strong example.
