Curious if anyone has had a titanium tube crack before along the engraving. Think it’s an old SDTA body but has less 200 rounds of 300 blk out through it. I saw it by total accident and got lucky it’s on a gun I haven’t shot in years.


Also, do any websites still sell the D-cell suppressor body?

It's a known issue when laser engraving Ti.
Either too deep an engraving and/or HAZ wasn't properly purged when doing so.

Do a search and you'll see plenty of posts on this topic.

Just wait till the end of the year and file for a free form1 for new tube.

It was a common problem a few years ago.  Laser engraving outside of an inert environment causes oxygen embrittlement in titanium.

I had a DM ti tube crack at the engraving.  The crack slowly spread until the tube became a ti sheet.  The engraver asked if I was going to coat it and I said "maybe".  He made the engraving extra blocky and deep so the ceracote wouldn't fill it in.

SDTA still sells their d-cell barrel shroud.

Solvent traps direct sells ti and carbon steel d-cell bodies.

Just had a Ti tube laser engraved.  I did not know about the controversy.  I asked the engraver (a popular common outfit) if any of their customers had a tube open up, and they had not heard of it.  The engraving looks about .005" deep and very well done and extremely professional. If they did shallow passes and managed the heat with a fiber laser, probably ok.  Time will tell. If I did it over, I would have looked into etching or mechanical means so no worries.
