If you're building a DMR or accurised AEG, the Delta Armory BERSERKER R-Hop Bucking Bundle for AEG is what you need to achieve maximum range.

If you use heavy BBs and need a range increase, this set will do exactly that!

This HOP-up nub/tensioner is ideally paired with a Maple Leaf HOP-up bucking and like much-lauded "Flat HOP" nubs, is designed to provide a stronger HOP-up effect for heavy-weight BBs and to reduce side-to-side shot deviation, improving accuracy and range as long as you do your part.
The OHM Solid Edition is available in two different hardness degrees, 50° for standard FPS and BB weights and 80° for heavy BBs (0.32g+) and DMR FPS levels.

- Convert the stock HOP-up chamber
- For ASG Scorpion EVO SMGs
- Includes all parts for TDC conversion
Turn your stock ASG Scorpion EVO's HOP-up chamber to a TDC design without having to replace the whole unit. This kit includes everything you need to install the system into your current HOP-up chamber. It is compatible ONLY with ASG Scorpion EVOs and will not fit in any other HOP-up systems.
TDC (Top-Down-Centre) HOP units are incredibly sought after due to the increased friction they add to BBs, which increases the effectiveness of the HOP applied to your BBs. By installing TDC to the stock HOP-up you are guaranteed compatibility with the platform.
The set also includes rubber nubs, these ensure the HOP is stable while BBs accelerate through the unit, further improving the performance and consistency of your ASG Scorpion EVO. This is a very complex installation process and we only recommend it if you are confident in your understanding and ability to fit it to your HOP-up chamber.

Krytac has taken the rotary HOP unit and added in audible and tactile clicks when you adjust, locking the unit in its set position and allowing you to adjust accurately even in low light conditions! The unit also has engraved numerical setting indicators around the adjuster, allowing you to keep track of which setting works best with which BB weight, avoiding the trail and error! This package also includes a KRYTAC HOP rubber.
