Umarex HDX Home Defense Extreme Marker T4E — .68 CAL · 16 J
Extreme situations demand extreme measures. The Umarex HDX Home Defense Extreme Marker T4E is a pump‑action .68‑caliber home‑defense marker built like a service rifle — full‑metal receiver, massive muzzle brake and a solid 3+ kg feel that adds stability and authority the moment it’s picked up. It’s designed for South African civilians and security professionals who need a powerful, legal, less‑lethal option that performs under stress.
Engineered to fire .68 rubber, pepper or powder rounds at up to 16 joules, the HDX delivers immediate stopping power without lethal force. The quick‑piercing CO₂ system keeps the marker on standby for months and readies it instantly with a light strike to the stock; an optical and tactile pressure indicator confirms you’re charged and ready. Intuitive pump action, single‑action trigger and a 16‑round internal tube make it fast and reliable in close quarters.
Whether you’re equipping a household, guard unit or security vehicle, the HDX balances intimidating presence with straightforward operation — law‑enforcement standards in a civilian‑legal package.
