So you know the stories about all the others who had the same problems with Brens made by your friend. If you don’t, just Google and plenty will come up. It’s the same over and over. Gun doesn’t work reliably… sent it back once or twice.. builder says it’s fine.. it’s still not reliable… what can I do. Are you going to try and blame all those people who bought your friend’s products too?
I understand how difficult it is to make a functional semi-auto out of the charred remains of a 70 year old gun. That beings said, if you’re going to sell them, they better work, because the folks who spend thousands of dollars are expecting them to.
In my humble opinion if your friend would spend more time trying to fix his product he wouldn’t have to spend so much time trying to defend it.
