When I came across this the first person I thought of was Rudolph. price is a little steep but it’s probably worth it https://www.gunbroker.com/item/909469228
You’re right, it’s up my alley. But: “This is what I believe to be a 12 guage 8 round FN A5 magazine tube and extended handguard.” And the return policy is not specified. It’s a little steep for something you don’t know if you can use, or even return. Hell, it’s steep even if it just “drops in”. Besides, I already have this: I think it cost me $75.
