Now to list it on the BST for him.
Glad to hear that your Shocker issue was resolved -- chances are that if a Shocker has issues with shooting that it is likely due to an Oring (in most cases a SINGLE Oring), but more often than not the likely culprit seems to be the bolt sail Oring. Furthermore, some folks get easily deterred from wanting to fix a Shocker after rebuilding it (i.e., replacing the Orings) because after doing so did not remedy the problem, and the irony in that is that not all Orings are made the same..the only thing I can suggest to them is to keep trying different Orings for the moving parts (e.g., bolt, bolt sleeve interior, and firing can interior), and of course coupled with a general base line of dwell and input pressure. Food for thought for others
