Yes on proof pressure's. I will take the latest one apart myself, I have repaired and fitted barrels on a baker (only time I tried, and spent weeks of time, I pay people who know what they are doing now) made it a 12 16 combo with 2 extra locks. It worked and turned out decent but didn’t care to much about it. This platform is much stronger, hope we can make it feel a bit more lively and look like something.
