The DM ASR tube takes the Nomad/Omega version of the Key-Mo.

I emailed DM but didn't receive any response. Will the DM SiCo ASR machined tube work with the Keymo designed to retrofit the Saker can? This Tube DM Sico ASR tube This Adapter This Adapter Reasoning is I already have a Sandman L and the muzzle devices to fit it. This would be a little more on the front end but would be more compatible with the devices I already have. |

Someone finally got back to me on this and I put in my order. The linked tube will fit on the Dead Air Keymo adapter. I should have it in a few days so we will see.

Do you mean the tube isn’t round or that the face against the adapter isn’t a square cut?

Thread cuts aren't deep enough to let it thread on completely and have the 2 flat faces meet each other. I plan on addressing this when I go over to use the lathe to finish this thing off after I get around to getting it marked. It looks like the threads cut for the KeyMo in the tube were not completely cut on the inside. Quote HistoryQuoted:

There has been posts at the other board about this and out of spec threads. I have a customer in this same boat and dm told him the module threads in nothing wrong.
What i did was bored out the asr threads and threaded that end 24 tpj. Made a thread adapter to fit the tube to thr ac824 module. It tested great on my 308. Here are some pic links. https://photos.app.goo.gl/wB6HHcrTSsHCmmUPA https://photos.app.goo.gl/jASqF9TxB4DTAzfSA https://photos.app.goo.gl/wjopXRbKKLBGZdhEA |

I was asked what the wall thickness is on the thread adapter tube threads. The thread adapter has an id the same as the asr unthreaded od that extends in the tube. 1.314. The od of the threads are the major diameter at 1.430.
The tube itself has an od of 1.5 and the minor dimension of the tube threads is 1.395. All this means is the asr thread adapter i made is stronger than the tube itself with thicker walls. |

I looked at a 2nd asr tube made by dm and it appears to be made the same way with the minor dimension at 1.348. Ir appears the tube was bored out to 1.350 then threaded 24tpi to end up with the minor dimension out of spec
.008 too large. |
