Didn't want to sidetrack the other thread that discussed both Bear Creek Arsenal rifle and pistol barrels so starting a new thread to focus on 40-9mm conversion barrel.
During Black Friday, thanks to member funklord12, I ordered 2 BCA conversion barrels for $42.99 and free shipping (It's still $42.99) - https://www.bearcreekarsenal.com/bc...-9mm-conversion-barrel-stainless-steel-finish
I received the conversion barrels today and did some checking. BCA barrel has 1:16 twist rate, same as Lone Wolf barrel, which is what most aftermarket match barrels run (Wilson Combat recently changed their barrel twist rate from 1:10 to 1:16). BTW, KKM has 1:20 twist rate and Tactical Kinetics has 1:10 twist rate.
Using my subjective reloaded round hand "feel", I noticed BCA chambers felt slightly tighter than KKM chamber (on par with newest Lone Wolf barrel chamber which is tightest 9mm chamber I have seen. Yes, the one that has almost no leade and I need to load rounds shorter) - https://www.thehighroad.org/index.p...g-oal-col-for-reference.848462/#post-11068321
Both conversion barrels "dropped in" the slide with reliable slide function.
As shown above, BCA barrel came reamed (like my older Lone Wolf barrels).
The following dummy rounds I had on my bench dropped in the barrel freely with a "plonk" and spun without hitting the rifling and fed reliably from the magazines (factory Glock and Magpul 9mm magazines):
