Using Donny Extender As Air Stripper On Bulldog?

[Pinzy]

 Hi all, I have searched the forums but haven't found the info I need before feeling comfortable enough to purchase the required parts. I am planning to buy a Donny Emperor and extender tube for my Bulldog, but I would like to reduce the overall length by mounting the extender tube further back on the barrel using Donny's Airforce Texan 308/357 (.625mm) adapter. So after cutting the shroud back and mounting the adapter further back, 4~5" of the barrel would be inside the extender tube. My plan is to use a db meter/POI to fine tune the adapter location before cutting the shroud to the correct length. Has anyone done this before or have any ideas/advice?

Also, I might get a Texan .457 in the future, and was thinking to use .45 cal Emperor/extender tube on both the Texan and the Bulldog. I would expect a slight increase in noise level on the Bulldog. Finances are tight for me right now so it would be nice if I could use the Donny 45 Emp/ext tube on both rifles until then.

Thanks for any Help

Well that didn't work. The Donnyfl AFT m18x1 adapter has a step inside so that it only fits on the end of the barrel. There is not enough material in the threaded section to bore it out to .625" in order to slide it back on the barrel in order to reduce moderator length. Back to square one I guess.
