Nightmare XL RTA by Suicide Mods – 40mm Cloud-Chasing Powerhouse for Advanced Builders

The Nightmare XL RTA by Suicide Mods is the ultimate rebuildable tank atomiser built for advanced vapers who demand uncompromising flavour, colossal vapour, and total control. With its massive 40mm diameter, this behemoth of an RTA is designed for experienced builders seeking performance, precision, and presence. Whether you’re a cloud-chaser or a coil enthusiast, the Nightmare XL delivers top-tier power with Suicide Mods’ trademark quality.

Designed for Serious Builders – Massive 40mm Form Factor

The Nightmare XL RTA by Suicide Mods isn’t for the faint-hearted. With its imposing 40mm diameter and 57mm height (with drip tip), this RTA requires a large mod to seat properly. It’s the perfect companion for box mods like the Hammer of God 400 or other 4-battery setups, built to push serious wattage and unleash enormous clouds. Its extra-wide footprint isn’t just for show—it’s necessary to house its advanced dual-coil floating postless deck, expansive airflow system, and large e-liquid capacity.

Precision Stainless Steel Construction

Made from premium stainless steel, the Nightmare XL RTA by Suicide Mods is as tough as it is refined. The CNC-machined floating postless deck offers ample space for advanced coil builds, including parallels, aliens, and stapled coils. A built-in chamber reducer compresses vapour for a more flavourful draw while smoothing airflow and moderating heat, ensuring performance without compromise.

Deck & Coil Layout – Floating Postless, Built for Big Builds

The Nightmare XL RTA by Suicide Mods uses a floating postless dual-coil deck, just like the original Nightmare family—but on a much larger scale. With extra space for complex builds and full airflow coverage, it’s perfect for high-wattage vaping with smooth, flavour-packed performance.

Top-To-Side and Top-To-Bottom Airflow

The Nightmare XL RTA by Suicide Mods uses both top-to-side and top-to-bottom airflow, funnelling air directly over and under the coils for layered diffusion. This airflow system not only boosts flavour and vapour density, but also keeps the tank highly leak-resistant. Whether you’re after a tighter RDL hit or a wide-open DTL performance, the adjustable airflow control has you covered.

Leak Resistance Meets High Wattage

Thanks to its top airflow design, the Nightmare XL RTA offers a cleaner, mess-free experience compared to traditional bottom-airflow RTAs. This makes it ideal for thicker, high-VG e-liquids and high-wattage setups, allowing you to vape intensely without experiencing dry hits or flooding issues.

Top-Fill Convenience and Massive Capacity

Depending on the model and region, the Nightmare XL RTA by Suicide Mods supports up to 12ml with straight glass or 15ml with bubble glass. Its top-fill system features wide ports compatible with Unicorn and Chubby Gorilla bottles, making all-day vaping convenient and spill-free.

Three Striking Finishes

Choose from three stunning finishes—Matte Black, Stainless Steel, or Electric Gold—each offering a bold look to match your custom mod. Whether you’re looking for stealth or shine, the Nightmare XL RTA by Suicide Mods complements any setup with a serious attitude.

Built for Performance, Not Beginners

This RTA is built for experienced vapers. It requires manual coil installation, wicking knowledge, and a suitable mod with at least 40mm of clearance. It does not come with pre-installed coils, so it’s best paired with performance coil sets that can handle high wattage. For top-tier builds, we recommend using Coils by Scott—handcrafted coils designed to elevate the flavour and vapour output of the Nightmare XL RTA.
