Mattw Posted June 30, 2008 Report Share Posted June 30, 2008 Hi All, I have been toying with the concept of making a silencer for my escort, I do not want to drill into the barrel it isnt an option. However I reckon I might be able to use one of the 4" extended chokes (that protrude past the end of the barrel) and drill into this to make it ported before fitting a silencer over the outside and then down the barrel. It would obviously be removeable as well which is a bonus. I havent found anyone doing these chokes has anyone else? if so where from and how much? Can anyone else see major problems doing this? or point out my obvious stupid error? Thanks in advance Matt Quote Link to comment Share on other sites More sharing options...

Spaniel Posted June 30, 2008 Report Share Posted June 30, 2008 Think it best not to play around with this idea to be honest, doubt you would get many chances in getting it wrong Ian Quote Link to comment Share on other sites More sharing options...
Mattw Posted June 30, 2008 Author Report Share Posted June 30, 2008 Very intersting article, But the Hatsan extended chokes are basically an extension to the barrel so hopefully this shouldnt happen? I guess the other way to do it would be to put the silencer slightly past the end of the barrel with an opening slightly bigger than the end of the barrel, as long as it isnt too far then the shot wont have spread out far enough to interfere with the silencer?

In a nutshell- you can't get the extension chokes for the escorts in the uk. This accessory is not imported into the country. I have tried to get them through a few different channels but to no avail. I have tried to match different chokes to ascertain the escort thread size. Beretta mobil chokes have a 1mm shouldered pitch, and are indeed the closest match to an escort choke. However, after owning three escorts semi's every gun I have checked and found to be as much as a thou or two different- they are just not uniformally cut as consistantly as other premium guns. The long and short of it- Hatsan screw cut their barrels with a thread size which is a near enough tolerence wise for their chokes to fit. To be honest I could not even figure out if the thread was imperial or metric, it is all over the place. Hatsan barrels are probably made in workshop in a back yard while Beretta or Browning's turn out their gun's 100 after 100 to the same tolerances everytime. As the saying goes 'you pay for what you get' springs to mind. I have also asked the same question to a couple of gunsmiths who have also given up on them in that respect. Best to use them for what they are a budget 'no frills' gun, and forget about extra's. Edited June 30, 2008 by starlight32 Quote Link to comment Share on other sites More sharing options...
harpo_the_bad Posted July 1, 2008 Report Share Posted July 1, 2008 As the saying goes 'you pay for what you get' springs to mind. Hello Starlight, I'm a design engineer for a company that produces quality precision tools for industry. A mystery thread that doesn't match anything or appear to conform to any standard doesn't always mean poor quality. Many of the tools we make have BIZARRE threads. Stuff like 35mm-12UN. Metric size, imperial thread form. It's not metric or imperial, it's both! We often make a point of mixing them up too. As you have mentioned, the Hatsan threads, like ours, are probably screw cut. Many companies do this on their tools. The usual reason is to prevent any competitor or client from making anything that will screw on securely (i.e. accessories or spare parts) in order to increase safety and more importantly: stifle competition. Dirty trick, I know... and I wish companies wouldn't do it because it makes things harder for everyone... including us designers and the machinists who have to cut these threads. Chances are though: it's not a case of low quality, more a case of preventing people like Matt from doing what he's trying to do! Quote Link to comment Share on other sites More sharing options...

I am surprised a company such as Hatsan bothers blesses us with a unique thread pitch-I mean a set of Hatsan flush chokes are only a tenner, where as Browning and Beretta allow for aftermarket copies of their accessories. I too often see bizarre threads which you mentioned earlier- Not as copy prevention but on certain assembly's with-in steam turbines. If that is the case, I see absolutely no need for Hatsan to prevent aftermarket copies of its accessories due to the worldwide success of its product, as is the case of other well known manufacturers. Prior to the age of Whitworth and imperial, the victorians made up their thread sizes unique to the job. Obviously this was a complete waste of time for compatability but it did indeed prevent your design being improved or repaired without the aid of the person who designed it...... Good point Harpo, however now I know who you are I can now blame someone in the flesh for all the years I have spent in the Engineering industry trying to fathom out how to put square pegs in round holes Quote Link to comment Share on other sites More sharing options...
