About
What it is, and why it matters
The Zastava M19 is a Serbian modular assault rifle developed by Zastava Arms and adopted by the Serbian Armed Forces around 2020. Part of the company's Modular Combat System (MCS) family, it is a select-fire, gas-operated rifle using a long-stroke piston and rotating bolt, chambered primarily in 7.62x39mm with a 6.5mm Grendel option. It features tool-free barrel changes, a non-reciprocating charging handle, ambidextrous controls, a side-folding adjustable stock, and a full-length Picatinny rail. The M19 is intended to replace the long-serving Zastava M70 in Serbian service.
The M19 represents Serbia's first clean-sheet domestic assault rifle since the Kalashnikov-derived M70, breaking from the AK pattern with a modular, tool-free swappable-barrel architecture and a non-reciprocating charging handle.
Developed alongside the 5.56x45mm NATO M20 as part of Zastava's Modular Combat System (MCS) line. Barrel lengths include a 254mm carbine and a 415mm standard configuration.
