That went fast. I added to my cart and went back to work. 1 hour later, it's all sold out. I prefer Brownell's offer (with 15% discount coupon) as I don't need the black spring and hinge rod the H&R offered.
Well, next time, lesson learned, need to buy it on spot. You snooze, you lose.
Brownells get's A1 port door restock almost the same time as H&R release theirs. Make me believe they are sourced from the same place.
