Dec 27, 2016 · 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.

Apr 2, 2021 · The 37mm m203 copies that LMT made for Brownell's are a different design that will not accept a 40mm barrel. And I do not know if the 37mm barrels will fit a standard m203. This difference is to keep them from being considered a firearm …

May 4, 2018 · I suspect whoever authored the Brownells description was misinformed, unless LMT changed dimensions on the receiver rails and stuff. I doubt they did. I recommend getting 40mm and skipping a 37mm barrel. 40 is cheaper, and …

Nov 11, 2019 · LMT just confirmed again that the brownells 203's are not interchangeable with 40mm barrels and the 37mm barrels are not interchangeable with Mil spec M203's. Posted: 1/4/2019 10:36:38 PM EDT

Aug 16, 2023 · I did and I am NOT trying to create a bash or b!tch session about the "unnknown delivery date". I am simply asking if anyone else ordered and maybe someone has a little industry insight as to when LMT may produce this run. I am patient due to being an NFA collector. I did not go the NFA DD route as I have 37mm ammo in my inventory already. Thanks!!

Apr 9, 2020 · The problem with 37mm signal launchers is the lack of standardization of the chambers and cartridge dimensions. How does this relate to light primer strikes? Well your rim recess at the end of your barrel could be cut for thicker rimmed shells, allowing the shell to slide too far into the barrel and away from the firing pin.

Mar 1, 2019 · The Havoc is rail mounted so it won't work with a M203 handguard (not without some kind of major modification at least). If you want it to look correct you'd have to use one of the LMT 37mm M203s. Otherwise the Havoc can attach to …

Aug 7, 2018 · LMT recently released a 37mm smooth bore "lookalike" M203 which cannot accept a standard 40mm barrel, therefore it is not a firearm. It is also not a real M203 receiver. I have a Cobary 37MM launcher, but don't know if it's something I can …

Jan 8, 2025 · LMT M203FL 37MM mounted it on a PSA 711 upper. It's a range toy but what are the basic rounds should I get. Also what about these Hornet Nest or Beehive rounds, legit or just a gimmick, illegal?
