Δημήτρη βάζω εδώ την απάντηση του ίδιου του κατασκευαστή σε ερώτηση κάποιου σε αμερικανικό φόρουμ .
First of all let me clear the air....the only chokes we ever had a problem with was one small production run of Opt HP and Optima. There was a typo error on the new CAD drawings and the taper length on the ID was too short which created too much outward pressure and the chokes would swell and get tight, if you kept shooting it, the choke would split and if you still didnt catch it, the extension head would possibly break, THAT was the extent of all our failures out of THOUSANDS of chokes in the field. The Optima is our biggest seller and we only had approx 72 customers receive chokes from that recalled batch, but when your on top of the market with a revolutionary new product, alot of people talk up the bad news rather than the good, SO....if a Muller Choke fails, it will NOT hurt your barrel, and unless you have one of these older recalled Optima chokes, you will NOT ever have a problem. If you do have a problem, we replace or refund with no questions asked. There is no problem, no risk and no worries. I assure you there is no danger or worries associated to our awesome chokes!
