I already know this post is gonna bring the hate but here we go!
When it comes to suppressor, your use is a very important factor for you.....
The can will live on a 11.5” AR15 but I was told I should upgrade to a 30 Cal suppressor so I can use it on my 18” AR10.
So with an AR we have a hire rate of fire, volume of fire and what does this mean to us? this means heat and abrasion.
Thus we can immediately eliminate anything that has titanium baffles(this means no thunderbeast!!).
If we want super durable we want inconel or even better stellite. You may see stainless steel or chrome moly in cheap suppressors but buyer be ware.
Now WHY becomes the big thing. Titanium is light and strong BUT when we are stringing shots without allowing time to cool it will get hot fast and rapidly erode and decrease usable life FAST, Yikes! Now with Inconel and stellite they retain strength when hot, they are also very very hard and brittle, not ductile. What this means for us is as we shoot that sandblasting effect from shooting (especially in short barrel rifles) that abrasion has less effect. Aluminum does ok but very dependent on what kind they used, they range from burning your money to great for their purpose.
Where would an all titanium suppressor be useful to us? Hunting? Absolutely. Bolt action slow and methodical shooting? Definitely. Each have their use and their place. Not that we can’t use them in other applications but user beware of what you are doing.
Recommendations? Dead Air, the sandman is a beast! Rugged, surge or radiant, the radiant will have lower back pressure and the first 2 baffles are stellite. I recommend jumping on silencer shop, sort by caliber 7.62 and then by material Inconel and Stellite. Then do some research. They won’t be cheap but they will last significantly longer.
The biggest thing to ask yourself is do you want heavy duty durability last a long time or do you want something light and easy, low round count when shooting? Or maybe to hell with it and have money to burn! That is all up to you, your use and situation.
As a side note, titanium suppressors have been studied on an AR, you can basically do a mag dump or two before it hits temp and you can either rapidly increase erosion or let it cool off, the choice is yours. This depends on a few factors but with an SBR just call it one.
