I provide these as an alternative to barrel threading which generally requires a minimum diameter of 15mm to give sufficient shoulder for adequate moderator base support. These adapters are precision bored to provide a nice sliding fit on the muzzle and are attached
by grubscrew or Loctite. The latter, which allows a thinner wall design is semi-permanent and can be removed with
a little heat.
Another type of adapter is shown in the miscellaneous section.
The selection below shows examples in brass, stainless steel, and polished
mild steel before and after chemical blacking.
They all have a 1/2" X 20UNF male thread, for attachment of sound moderator.
Some are shown with optional custom thread protector ring which I make in various styles to your specified design, with or without knurling or banding etc.
Please note I require an accurate barrel diameter and the calibre to be specified when ordering.
