HOMEDEFENCE-24: Professional Upgrade for Umarex T4E HDB / TB 68

The BUTTSTOCK adapter T4E HDB / TB 68 for Umarex shotguns is a key accessory for every owner who wants to take their gun's performance to a new level. This adapter serves as a connecting element between the gun body and an air tank (HPA) or an 88g capsule (when using an ON/OFF adapter). It is made of high-quality steel with a black polished finish, ensuring extreme durability and stability.

With this upgrade, you get not only a much larger gas supply for your gun but also the possibility of installing a stock, which improves ergonomics and recoil control. The total length of the adapter is 7 cm and it is equipped with an integrated O-ring for a perfect seal. The installation is precise and firm, so the adapter holds reliably even during intensive tactical training.

Installation Warning: Successful mounting on your gun requires modification of the plastic cover (cutting/adjustment). Please note that we assume no responsibility for this conversion or any modifications to the gun. We recommend performing the installation carefully with regard to maintaining the functionality of all mechanisms.

Frequently Asked Questions (FAQ):

Can the adapter be used for other types of guns?
This model is specifically designed for Umarex T4E HDB and TB 68 models; compatibility with other guns is not guaranteed.

Do I have to permanently modify the gun during installation?
Yes, installation requires modifying (cutting) the gun's cover to allow the adapter to be properly routed out.

Will using HPA increase my gun's power?
The HPA system primarily ensures consistent pressure and a higher number of shots without a drop in performance due to chilling, which is common with CO2 guns.
