Cool idea for a thread. Could put to rest (or reinforce) a lot of the concern about wearing out baffles. Maybe add barrel length as well?

Excellent idea, let's try to add barrel length and caliber the can has been used on primarily.
ETA: I really wish I had taken a pic of the blast baffle when new but I didn't think that far ahead. If any of you guys have a pic from when your can was new please add that in too. |

good thread, how did you guys get close up shots like that without it being blurry?

And what barrel length? Probably 75% was with a brake. I've ran it very hard at times as well...several mag dumps In a row. Mostly with 11.5 BCM and 10.5 LMT. |

Not visible are the rest of the baffles, all of which have absolutely zero apparent erosion. |

So you are saying God hates these endangered ducks?

The danger is not Barack Obama but those who elected him. It will be easier to undo the follies of Obama than to restore good judgment to the masses. We can survive Obama, who is merely a fool. We are less likely to survive the fools who support him.

This really is a great resource to check what the inside looks like! It has helped me greatly...I worried about how mine started looking but now I see it is normal!

Am I seeing that correctly? It's probably has something to do with the mold the baffle was made from. There's no way. Judging from the orientation of the locking gate, it looks like the "top" of the silencer (and therefore the open slots on the A2 flash hider) would be degrading those voids at 7, 9, and 11. NT4s are supposed to be built like a tank. That looks like a ridiculous amount of wear from that low of a round count. |

View Quote Those are great pics, thanks for taking those. The blast coming out of the slots in the flash hider is definitely wearing away those petals, but it looks like it's in an area where the wear will be self-limiting. My SDN-6 has a somewhat high round count, several thousand 5.56 out of a 10.5", a few hundred of that on full auto and the rest of it on a pretty quick firing schedule. I'll try to get a picture here in a couple days, but it still looks really good inside. I've baked off part of the finish on the outside, but inconel is apparently very, very durable stuff. |

Not a problem. Ya got me curious now. I may soda blast it and see how much is carbon/crud, or actual wear.

I am not sure on if the baffles are cast/machined or straight machined from block. With you actually bringing up that point, and how the NT4 is a high volume manufactured can for the Mil, I wonder if the baffles are cast to cut machining costs, and not fully machined.
I guess I should have taken a picture when I got it, but everyone knows how hard it is to think straight getting a new can and wanting to just shoot it. |

There are several contours that would save so much time and money to manufacture by casting them. And to keep this thread on topic here's my M4-2000 with a few thousand rounds shot on three different hosts: 10.5" 556 w/ muzzle brake 14.5" 556 w/ muzzle brake 20" 556 w/ muzzle brake Limited full auto I'd say less than 500 rounds. |

In all seriousness - a LOT of it looks like carbon build up to me. I wouldn't poke,prod, clean, etc. I would shoot it. They have a track record for running for 100K rounds. There is, literally, a 99.999% chance that you do not have the wallet to kill this can that fast.
Shoot it, Enjoy it, And get a different brand can next time |
