Cva tungsten qrbp and firing pin?

[B Ohio]

AnyOne have experience using tungsten qrbp and firing pin from CVA. I think it has less blowback

Interesting. I didn't know that cva had a tungsten breech plug!

I believe they make a Paramount plug with a tungsten bushing. Haven’t heard of a QR version.

Maybe the bushing is all that is tungsten

That would my guess. The flash hole is what erodes when the powder ignites, and the flash hole would be in the bushing. One thing is for sure, it would be easy to convert a standard QRBP: to a QRBP with a bushing, and at the same time make a plug that would reliably ignite Blackhorn.

One can purchase bushing, and hollow nut from Yellowstone, this i know, having done so.

Imagine how expensive, not to mention how difficult it would be to machine, a tungsten plug.
