I lost my breech plug (intended to mail it out for a BH209 upgrade modification) by leaving it laying around since Covid started and now I can’t find it. This is from an early 2000s Optima Pro. Long time before the Quick Release breech plugs were out. I found this on Midway: https://www.midwayusa.com/product/1002212567 I am just making sure I can just buy this and use it? I know Bolts for rifles are fitted to the chamber but I guess because there is no headspace in a muzzleloader replacing this piece is as simple as screwing in and using the new one?
