I should have purchased the CVA, QRBP, Optima V2, NorthWest breech plug 8 months ago like I had intended to. I wanted it as a fourth option for ignition in the Optima V2 pistol.
I already have a standard CVA 209 primer breech plug (#1) that came with the pistol when I got it from MtMonkey.
Instead, since I was so far away from Doc White getting around to making the new stocks for the pistol, I elected to wait to purchase the NorthWest breech plugs until later.
Silly Rabbit, Tricks Are For Kids!!!!!
Now, like dirtsailor2003 has stated, CVA is not making them, nor selling them as aftermarket parts.
Right after I got the pistol from MtMonkey, I purchased a Lehigh Defense #BH-BH-C1, CVA, 209 primer breech plug (#2), along with a package/4 replacement vent liners. This was going to be my primary breech plug.
I was going to purchase 4 of the CVA, QRBP, NorthWest breech plugs. My intention was to have a machinist modify them so that they could take a replaceable, AMPCO bronze, 1/4"-28 threaded, nipple. Buffalo Arms sells these nipples, both the same length, for either a #11 percussion cap, or a 4-wing musket cap.
I would then have a pair each, of CVA, QRBP, #11 cap, breech plugs (#3), and CVA, QRBP, musket cap, breech plugs (#4). These would be back-up plugs if 209 primers were unavailable.
Last, but not least, I recently acquired an Arrowhead, LRMP, CVA, QRBP large rifle primer module, breech plug (#5). Until the world went crazy, I intended to switch to the Arrowhead LRMP, rifle primer breech plug as my go to, everyday plug. Because, when properly installed, it becomes a closed system with no blowback, or fouling to clean out of the action.
Now, both types of percussion caps, and both types of primers are in short supply.
Who knew? The wind blew. $**! flew!
