Gents, I was hoping for some input on the jp supermatch barrels specificly compared to the shilens. I have contacted shilen and realize they don't use a SAMMI spec chamber, yet I find it hard to believe AA would put there stamp on one if it weren't approved my Bill Alexander himself. The JP barrels I believe are true SAMMI spec, yet I cannot confirm this. I'm looking at the 22" specificly, and notice they use a 1:8 twist wile shilen used the AA recommended 1:9 twist. Also unsure about the bolts that jp sends with their barrels. Any input would be appreciated, thanks.
