More surface contact and tighter threading is going to yield best results when you think about your can unscrewing from your rifle.
I also went 3/4x24 on my AWC T-Trap and being huge threads they lock up REAL tight!
Its all personal preference really... </div></div>
I could see the larger thread having greater strength, and if that meant that you could mount the product with more torque, that should imply greater mounting security.
However your ability to generate torque in this application is related to the strength of your arms, because most suppressors are tool-less installed items, so I believe the determining factor in the equation will be two things:
1. Thread pitch (24 in 5/8 0r 3/4 OD will provide the same result)
2. thread shoulder surface area- the more surface area, the less pressure per square inch will be attained. This will reduce locking force. So in other words reducing contacting surface area of the thread shoulder to rear of the suppressor will result in an increase in mounting security.
That may be why you feel 3/4OD threads lock up better for you- they may leave less mate-able barrel material at the thread shoulder. </div></div>
Your saying less shoulder on the barrel is better? I cant agree with that. You are relying on that shoulder to line your threads, the bore, and the bore of the suppressor. I am not putting a 338 AAC Titan on a pencil barrel with a light palma contour barrel. Thats asking for stupid things to happen. </div></div>
I was just going to inquire about that myself until I saw that you beat me to it KYS. The way I see it, you get more lock up with smaller threads, bc the surface area of the of the barrel's shoulder is more, allowing more contact with the can. More surface area = more friction = more lock. Tac Ops uses 9/16x24 threads for this reason; more shoulder contact than 5/8x24 threads (although they don't allow for as many options for brakes). I have 2 of my rifles threaded 9/16x24, an M40 and an MTU contour. They shoulder up with the cans nice and snug.
