Is that a piece missing at 3:00?

Good thread. Seeing some of the pictures has made me rethink going with just FHs on my 10.5” guns and getting hammer comps to act as sacrificial baffles.
|
|
|
Wow, even the mighty Stellite baffle yields to the sandblasting of an SBR. Would've thought if would take longer than that, though.
|
|

I have a sandman-s in jail right now. Seeing those baffles crumbling at such a low round count (compared to others in this thread) has me second guessing my choice.

The more I look at it, it might actually be "build up".

16” 5.56 seems OK, but some of these pics seem to be a PSA for running a sacrificial baffle muzzle device if you’re going to be doing a lot of, or exclusive, shooting of 5.56 out of a 11.5 or shorter 5.56.

@gck5150 and @abnt89,
Wow! That's very abnormal for a stellite baffle. Please contact our customer service and we'll quickly get these rebuilt for you. We have demo cans that have seen many thousands or rounds more than this that only have a slight surface impingement on the baffle. It's very thick, too, so if there is erosion it's not going to affect the structural integrity of the baffle. If I had to hazard a guess, there could have been some baffle strikes that cracked that baffle and accelerated the breakdown or it could have just been a bad casting. We investment cast the baffles because there's no reasonable way to machine this it. It's not unheard of to have a cast part that has porosity issues, although, this is the first we've seen it on our baffles. In any case, we'll absolutely fix this if anyone ever runs into it.

Either way I'll shoot customer service an email, thanks again. View Quote |

Not only is a 10.5 much harder on a can without a brake but there is such a thing called jacket separation. If you run a rifle hard enough the jacket can seperate from the lead core and strike the stack. Dead Air is always there when you need them! ;-)

So at what point of erosion is replacement necessary? What if it completely erodes? Is catastrophic failure imminent?
How much junk can actually accumulate in the can before it loses a noticable amount of performance? How much weight gain would that equate to on a typical (standard size) 5.56 can? |

View Quote All your questions depend on the design of the can itself and could only be answered on a can by can basis, if at all. Internal volume, baffle design, etc. You would have to know how much of the theoretical buildup would be lead and how much would be carbon. Without knowing that you can't know weight vs. volume which mean you cant know at what weight sound performance will degrade. Eta: not sure what the part in red is supposed to mean. What does "completely erodes" mean"? |
