About
What it is, and why it matters
The KRW 20 is a Czech blowback-operated, closed-bolt 9x19mm carbine of proprietary modular design, sold in configurations from a 120 mm-barrelled pistol to a 254 mm-barrelled carbine. The steel-bodied weapon uses a side-folding stock, Picatinny and M-LOK rails arranged around the barrel, and folds to as little as 357 mm depending on version.
Czech gunmaking did not stop at CZ - a cluster of small workshops around Uhersky Brod and Prague still build complete proprietary designs like the KRW 20 in numbers most factories would call a rounding error.
Figures given are for Version 2 (202 mm barrel). Shown by KR-Weapons at IWA 2026; added to close a catalogue gap rather than as a 2026 introduction.
