Hi All~
Sorry I just came across this thread, hopefully years of installing muzzles on all different types of Omer spearguns can shed some light on this and assist. REEF B - REEF B as well as the HHEAD - B (with elevator bar) are designed to fit 28 mm OD with 1 mm wall thickness barrels such as standard aluminum Omer Excalibur Beuchat Mundial. They also fit 30 mm OD barrels with 2.0 mm wall thickness these are primarily carbon fibre guns with thicker wall such as the Rabitech, Aimrite, and others. REEF A- Are designed to fit 30 mm OD barrels with a 1.5 mm wall making them an ideal mod for Rob Allens and Picasso spearguns. In addition they also fit the Sporasub models, eventhough Sporasun has a 28 mm OD they have a thin wall thickness of about 0.5 mm requiring a large base for installation. For more information on the strength of these muzzles you can watch this youtube infomercial YouTube - How Strong are HammerHead Muzzles? +Caution because these muzzles are hand cast polyuurethanes with glass frit and UV stabilizers they may have slight amounts of varience this can easily be overcome by sanding (the material sands very well) or by potting a small amount of epoxy or silicone.

I am sorry the bring back this thread, but just to put some closure to it, here is my black viper with the HH muzzle and one 20 mm RA band. The gun shot pretty well, but it took me a little longer to load, I wish the pin on the top of the muzzle had a little curve on it, that would prevent the line escaping from it.
The installation was straight forward, I've made sure to plug the barrel (it was leaking before any way), I've also used silicone instead of epoxy. One more modification I have on this black viper is the universal omer reel instead of the regular sporasub reel. This gun is 11 years old, besides breaking bands (my fault), it never broke or gave any problems. BTW this is my blue fish killer ! The Excalibur look and shoot really well, I forgot to take a picture of it ! Attachment 17162

Omer in italy is always very fast to answer, but you always can see and look on some omer catalogue were they have pdf on technical instructions on the guns.
Regarding the epoxy, epoxy usualy doesn´t like a lot of plastic of th head
