DayZ 2 + Badlands · Live DLC
SCR-17
The 1.29 rifle
Short answer
Road to Badlands (1.29) added the SCR-17 battle rifle to the live game, with a black variant for Sakhal. Not a Nasdara-only gun.
Also: scr17 · battle rifle
What we know
Official 1.29 notes named the SCR-17, stocks, a mag, and a Sakhal black variant. This is live-game kit, not a sequel leak.
What to do
If you find one, feed it. See guns-ammo. Don't chase it as the only hour.
Don't
Don't invent a spawn table.
