The improved sealing lips on the front and rear of this bucking have been designed and prototyped with molds tested up to three times to ensure optimal sealing and performance in the Kraken SRS chamber.
This bucking is engineered specifically for use with the SRS and Kraken SRS Hop-Up Chamber. Its unique design fits the stock Silverback cylinder nozzle size, eliminating all air seal issues. Along with its plug-and-play assembly, the need for PTFE tape is eliminated.
The unique dual side fins combined with the concave hop bucking design and internal alignment features of the Kraken Hop Chamber ensure your SRS setup remains perfectly aligned, delivering ultra-straight BB flight.
