Hiya Gamestop and thx for the thread, I have the Bren run as a pistol, not many rounds thru it but never a issue. At the indoor range here,the report from it seems louder than the other things on the range. Fun to shoot. I hope ya brought out something else to shoot when the Bren didn't work. Saw that ya had the smith at the range assess that other than the gun not working that the guns fine. This made my brain hurt a little. Akin to dropping my car off at the shop only to return and hear, your cars fine,it just dosent run. What else did your smith say and how much do they charge to not fix a gun?? With what you described last week, and slamming the mag in harder this week for a possible remedy, thats really not gonna change your result, but could damage where the mag seats and or the mag.
Our forum perhaps needs a sticky post specific to that fateful call to cz usa and its really nothing like have a root canal. Back on the 12th, customer service would have taken your info and likely emailed you the shipping labels and you'd prolly be getting you gun back fixed by a smith thats well trained in your Brens workings. They often provide some thanks for being a cz owner gift too. Be well.
