Alright, for anybody interested, here’s the first look. Parts came yesterday, and I hope to test fit them in an Omega tomorrow…so more pics coming soon. I’ll add some specs after the pics. Goal was to add another can I could swap around on my YHM-equipped hosts. Currently have a couple YHM cans, a couple Sakers with Y-Mounts, and multiple F1 cans with YHM adapters made by the same source.
Here was the first one (not shipped to me), made before I provided DM with the blast chamber length. All he had was the longer version of the YHM FH, so that’s what’s in the pic with the Omega ASR mount and brake:

And then here’s what I got. Longer version to handle 7.62 devices, shorter version for 5.56 and LT versions, and a direct thread:


Another one with the Omega ASR mount included:

And finally one with ASR mount/brake vs YHM mount/LT FH:

Now some specs. All of the pieces I got are Ti, so SS would be a little heavier but less expensive. Don’t have cost, yet…but can’t imagine it’s much different than the other adapters he’s made.
Weights:
Long YHM adapter: 2.9oz
Short YHM adapter: 1.9oz
1/2-28 DT adapter: 1.5oz
ASR adapter: 3.5oz
Short YHM & LT FH: 5.6oz
ASR & brake: 7.1oz
All the threads (SiCo and DM) are roughly .375".
Total length and outside the tube length (should be roughly .375" different, but I only measured once so could be off by a couple thousandths):
Long YHM: 1.537"/1.158"
Short YHM: 1.034"/.660"
1/2-28 DT: .570"/.193"
ASR : 1.204"/.830"
Blast chamber measurement provided was ~1.70". The ASR/brake combo and the YHM/FH combo are within .003" of each other from the shoulder to the tip (the portion inside the can). I believe the longer YHM mounts are ~.5" longer than the LT/5.56, and the longer adapter is basically that much longer than the shorter one.
Bottom line to me…I can mount an Omega on my YHM mounts with an adapter that’s ~1.5oz lighter and ~.17" shorter. Considering I plan on selling the ASR mount, the 7.62 ASR brake, and whatever muzzle device I choose when I register, it’s a no-brainer.
Thoughts? More pics to come once I get my hands on an Omega this weekend.
