Sandman S with maybe 1500 rounds of various .223 / 5.56 on a 10.5" LMT upper with flash suppressor mount.

I was just looking at the can and noticed the blast baffle is somewhat beat up so I figured I'd post a pic

Holy crap! Only 1,500 rounds?

I'd be interested in hearing what the manufacturer says about that erosion.

They have a pretty thick blast baffle. I'd imagine while it may round off the edges a bit it isn't going anywhere for awhile

Here's my sandman S that's had about 3000 rounds through it. It's been on a 10.5" with a flash hider the whole time and has only seen 223 in semi. Kind of looks like the above Sandman pic too as far as the blast baffle goes.

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.

Innovative Arms direct thread 5.56. ~8,000 rounds, half on a 16” and half on a 10.5” AR:



I’m really surprised (and pleased) at how well this IA can is doing.  It’s a little heavy for a 5.56 can so it’s built like a tank

Griffin Recce 5 Mod 3, ~3,000rds 16” AR


That little bit of build up is easily removed but it’s not enough to mess with right now.

Griffin Optimus Micro: ~1,000rds 16” AR, ~250rds 20” 224 Valkyrie and unknown 22lr



After cleaning the baffles I didn’t really see anything I’d consider wear.  This tiny can is a beast

Maybe I’m seeing it differently, but to me these Sandman blast baffles look to have build up on the non-clipped portion of the baffle.  Some of the buildup seems to have been knocked off giving it the appearance of the baffle being chipped or broken.  I have a Wolverine pending that uses the same baffle design so I’m hopeful that I’m right, but open to discussion.

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.

This is very atypical.  From my Silencerco days to now, I've never seen stellite wear this bad from such a relatively low round count.  I believe there are some special root cause factors as outlined above.  In any case, we'll definitely fix that.

Originally Posted By CJofFL:

Yeah, if you've ever seen a chip out of stellite, it's because there was a bullet that contacted it at some point.  It's an incredibly hard material for wear purposes, but it'll chip more than deform when a bullet contacts it.

Thanks for the replay Todd, it really doesn't bother me but I'll shoot them an email with some pictures and see what they say. Out of curiosity and maybe slight ignorance, and without derailing the thread too much, would it even be possible to have a blast baffle strike and still have the rest of them and the end cap be in perfect condition? Either way I'll shoot customer service an email, thanks again.

Yep, it happens.  I've also seen bores on suppressors that should absolutely strike (like if you shone a laser down the bore it would totally hit a baffle)--but nothing happens or it only strikes the front cap.

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!  ;-)

For comparison, here's my Sandman-S with approximately 4,000 rounds of assorted calibers through it.  75% of that is from an 11.5" 5.56 with a brake, the balance is mostly a .243 RPR and a 12.5" Grendel, both with brakes.  I couldn't get a very clear pic, but the baffles show no real wear, just lots of carbon.  None of my brakes are showing much measurable wear either.

Thanks, Todd. I suspected a baffle strike/graze or jacket separation might be responsible. The rest of the baffles appear to be fairly intact... just the normal combination of buildup and abrasion that just kinda makes them look fuzzy.

I'll get in touch with customer service in the near future. I might want to take the can to the range this weekend but I'll get it back to you guys soon.

I've noticed a fair bit less carbon since I started using Vihtavouri for my 300blk sub loads

What's the most you've run through the Paladin without breaking it down?

Have you ever tried the paladin tool on the optimus?  I've had to beat my baffles out with a dowel, it's not a big deal but I'd much rather use a press tool

Actually, those pics tonight of the Palidan.. it's never been cleaned. But it's run mostly on an 11.5" 556 and a 22" 6.5cm (both semi and bolt).
And as you can see, it's due for a cleaning.

Im gonna experiment with different powders for my subs going forward..  I'd be interested in your load, I don't mind cleaning but damn. Lol.

to answer your question about the Optimus baffle pusher... works like a charm with the mid length (blast shield).
I'll never again beat my baffles out.. it's just too easy with the tool.

This is what my Sandman K currently looks like.



Don't have an exact round count but I'd say roughly 200 .300 blk subs, 500 .300 blk supers, 200, maybe 300 mixture of .223 and 5.56 spec ammo.

Hosts, 16in bolt .300 blk with the brake.  AR pattern guns, 8.3 .300 blk with hider, 10.5 and 16 .223/5.56 with hider. Also I should probably mention that most of the .300 blk has actually been through the bolt gun so not nearly as abusive as it is with the shorter setups and that one has the brake on it.

As and ye shall receive. This is the only pic I have currently, has a chimera on it, but I use the K to keep it short. Also pictures is the 5.9” .300Blk that I use it on.



And to keep it on track, here is a Saker 556k with about 300 rounds. Mostly a 16” gun.

Lightly cleaned. Mid configuration with 3 prong seems to have sped things up.

This is after the first 100 with 3 prong.

Shouldn't be too hard to replace when it does eventually wear out
The other 900 rounds in mid config were from today. Need to crack open another case of ammo, another case of beer, and reload all my mags for tomorrow.

Sounds like a hell of a good time

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?

As far as your second two questions:

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"?

I would worry about uneven erosion possibly upsetting the bullet due to turbulence, which might eventually affect accuracy or lead to a baffle strike.

I think you would need to severely erode more than one baffle before you notice a significant change in performance, but I am not an expert by any means.
