Contact Don Cothran. He machines many specialized items and is reasonable on single items makes a lot of nice Airgun parts also. https://cothranmachine.com/
Nope. If you really want one that bad, just take your tube and have a local shop copy it. It'll be expensive though... You want a factory length one, or a short one?

Especially expensive doing one or just a few. The tooling involved, Fixtures and Machines along with the knowledge to do it in this day and age ... near priceless !!!
I could see Crosman mass producing this item and selling it for $159.00! I would pay...

I would pay...Sadly, I don't think we will ever see a major American manufacturer offering these, either as parts or in their base products. It is just too risky for them over the long term, given the material properties of Aluminum. Eventually, even with completely normal usage in the recommended pressure range and good care, there will be failures - and I am talking decades later, but the long reach of legal liabilities in the West is powerful. Not to get into the details, but unlike steel, Aluminum has no fatigue limit - every stress and cycle contributes to work hardening - so even used properly the material properties change over time. That very small risk has big implications to companies looking to be around for a long time. Don't get me wrong - they have their use and I bought two of them from JSAR back when they were made (both for Gen I, with one 3" longer than stock and I wish I did that to both of them - neither are for sale). But I bought them knowing that they had a limited lifespan and will eventually be decommissioned.You will always be able to find someone or small shop to make them, and "offshore" companies that can't be touched by our legal system may make them, but it is just not going to happen from the "big dogs" in the West.Unfortunately, the best answer from these manufacturers is the more expensive titanium . . .
I had a local machine shop in my country make one, 2.5" longerhe used a fancy mill with the holes/slot programmed and with a lathe for the fill end threading.Was not cheap as expected.

The first one will ALWAYS be expensive, since you have to design the program. BUT once the program is made, the machine can spit out each subsequent piece for relatively cheap.
correct, he has the program settings for everything now to cnc mill the holes and slotsall he has to do is clamp the tube in the holder and let it run and do the 90 rotations along the waya cnc mill not cheap though and the expertise to use it is not trivial either.the threading requires a little more manual work with the lathe.The trick is to find a machinist who is willing and understands the market, many of them have a lil attitude problem lolbut then that is how a lot of the good craftsmen are.I also had to paint mine as wasnt able to anodize it, which adds to cost.Quote from: YEMX on July 27, 2021, 08:17:39 AMQuote from: lennyk on July 27, 2021, 07:35:29 AMI had a local machine shop in my country make one, 2.5" longerhe used a fancy mill with the holes/slot programmed and with a lathe for the fill end threading.Was not cheap as expected.With a CNC machine, your cost savings will be in volume.
