I would like to put a moderator on a Hatsan Bullmaster,does anyone know how to do this ,or what to buy.I have seen some footage on YT but there were no specifics on the how to.
Best look at the Donny FL page, https://donnyfl.com - I cannot confirm the fitting, but a quick email to Donny will get you the answer - he is quick and really helpful - probably be able to tell you exactly where to get the kit from.
I have a Hatsan Barrage 0.22CAL with QE (Quiet Energy) barrel. At the time in 2018, a friend of mine made me a 1/2" UNF barrel end adapter with screw thread protector on his C+C machine as there were no adapters available worldwide at the time. DonnyFL now sell a QE-1/2" UNF adapter......i've got one installed on the end of a Hatsan Galatian 0.25CAL, bought from Krale in the Netherlands. Hope that helps
