The key to fitting a moderator correctly is all in the threading

There are five key aspects to the thread:

  1. The thread MUST finish at the abutment end with a clean thread and not taper out - in practice this means cut on a lathe with a point tool (Not a die-nut) with an slight 2mm undercut at the abutment end



  2. The thread MUST be parellel to the bore - again in practice this means cut on a lathe with a point tool (Not a die-nut)



  3. The thread MUST be concentric to the bore - again in practice this means cut on a lathe with a point tool (Not a die-nut)



  4. The Moderator must be slightly lose on the muzzle thread - in practice just before the mod stops with a nice "clunk" against the abutment the mod should have 2-3mm of "wobble" at the far end

    If your moderator is fitted by someone less familiar with the specifics of moderator threading,  they are likely to fit a "nice tight" smooth thread - unfortunatly this results in the moderator aligning with the mod thread/muzzle thread instead of squaring to the abutment face - which is the most accurate



  5. The abutment face MUST be Square to the bore - again in practice this means cut on a lathe



And finally

The Back-Bush MUST BE FITTED on modrators where they are supplied/designed for - T8, T4, etc - most reflex (back over the barrel) types
