ASA Tuning HEAT CORE Chamber for Umarex T4E TC 68 16 J and 40 J

The HEAT CORE Chamber is a replacement valve body with an enlarged air chamber designed exclusively for the 16 J and 40 J versions of the Umarex T4E TC 68. The larger internal volume allows the gun's power characteristics to be adjusted, while the integrated gauge provides an overview of system pressure.

The original gun spring is retained on the 16 J and 40 J TC 68 versions. A new spring is therefore not included in this package.
