Reply To: Quick marauder valve question
Gen 1 or 2 ? Original Gen1 ( may have changed after a couple of years? Someone will know) had a different valve for the .177/ .22 and the .25. A preformance gain could be had switching in the .25 valve.
Sometime ( ??? ) before the Gen2 model the valves were unitized with all cal. being the same.
Transfer port may be different?
