1/2X28 female to 5/8X24 male

[N310toN170]

So, I'm looking to have my can thread on to a barrel that is only .532" inches in diameter. Means I can't thread it to the standard 5/8" x 24 TPI and am gonna have to use 1/2" x 28 TPI and get an adapter.

Does anyone know where to get such an adapter?

My initial search lead to Tactical Innovations but I'm not into paying $60-70 for such a simple request. I could have a local machinist do it for $20 and a beer but he's kinda backed up right now and I am needing it to be very, very concentric.

Ideas?

Unfortunately, TI carries TROS at $69 and is outta stock.

I picked one up for $35 plus shipping. I'll continue to post on the quality once received.

I ordered one from Element Arms about 3 weeks ago for $56 delivered. Haven't heard from them since the order.

Unfortunately the PRI model doesn't have a flat area where you can use a wrench to tighten.

I'm afraid that with the heat and thread combination that the adapter could quickly become stuck, or having to use a anti-lock compound that it wouldn't stay secure.

I'll post again once I receive and do a quality review.

I just bought the 1/2-28 tap to make up a few. I can make any shape you need...Bob aametalmaster@yahoo.com

As promised the follow-up:

The machining is clean and crisp, the finish is a good matte black (not glossy like their pictures). The communication was good via status updates by email. Looks like it was a very legitimate product and I'm pleased with the overall quality and service.
