ABSTRACT:
In an explosive powder operated device using caseless powder charges for firing fastening elements into a hard receiving material, the firing chamber in the barrel of the device is defined in part by one end of a counterhammer. The one end includes a sealing ring having a frusto-conical sealing surface supported on a correspondingly shaped surface on an axially extending body part of the counterhammer. When a caseless charge is ignited in the firing chamber, the explosive gases generated act in direct surface contact on at least a portion of the sealing ring which faces into the firing channel.
