I know Randy Shivak used to make these, and I know there is another thread about this, but are there any options for getting a 37mm barrel made for a Title 1 LMT m203 receiver? I understand that some have hinted at doing a run of these in the future, but I am interested in getting this project underway now. Is there anyone who can weld a 37mm sleeve into a 40mm barrel as I read Shivak used to do? I am NOT interested in going the NFA route, as the NFA itself is nothing other than socialist tyrannical government outreach. There is something more than a little off about paying hundreds of dollars, waiting 10 months, submitting passport photos and fingerprint cards to the government just so you can exercise your God-given rights as protected by the U.S. Constitution.

Been looking for these also, PM me if you find a lead on any. At this point, I think it might be easiest to just buy a 40mm barrel and pay a local shop to sleeve it down to 37mm.

Last word I got was that you could look for them mid year from LMT.

Thanks for the responses. Where did you hear LMT is planning to offer these barrels in 37mm? That would be great if true--the most ideal solution, in fact.

I was wondering what shops/vendors would be willing to sleeve a 40mm barrel down to 37mm. I can't find anyone willing to do it, so please let me know if anyone has a lead on that.

From an industry contact as I was doing research for an upcoming 40mm article I'm working on.

Excellent--thanks again.
