I will presume you mean the tube part of the shroud separated from the “adapter” piece that goes between the tube and end of the gun. If in fitting the two back together the they slip together with minimum resistance I’d try JB Weld (not the fast cure variety) Mix and spread a light cote on both inside and outside connecting surfaces and push together give 24 hrs cure time. If tighter fit (have to tap the two pieces together) I’d try Locktite Red threadlocking compound, again with 24 hrs cure time.
A friend of mine has an AH shroud and if I remember right there is no “indent” for the set scres to fit into. Where the set screw has made a nice mark in the shroud, I’d drill a small recess, same diameter as the set screw 1/2 the thickness of the shroud. That way the screw would tighten INTO the shroud slightly; instead of AGAINST the shroud where it can slip. That would allow just a “firm” tightening of the set screw with no worry of it slipping.
Yes, I have a TalonTunes Shroud. Started with a BullseyeBills Frameextender and added baffles….good but no comparison to the TT.
The AH on my friend’s Condor was quieter than my BB extender but had a very noticable “metallic ping” similar to a high performance v-8 car engine with aluminized exhaust tubing. The TT shroud has a less metallic sound kind of like a WHEEZE and is much quieter. The TT shroud on my .25 with 31gr kodiacs over 1000fps makes about 1/3 the noise of a stock .177 TSS with 10.2gr kodiacs at 850fps.
Looking through the AH shroud I counted 3 baffles, the TT shroud I count a Minimum of 6. Knowing the work that must go into one of Anthony’s units, I consider his price a bargain.
