37mm to 26.5mm Cartridge Adapter

Dude you may be “experienced” but it clearly says 37 conversion to 26.5. NOT 40mm, it’s pretty obvious everything you said is absolutely pointless and redundant, you gave 4 stars because it didn’t function perfectly in something it wasn’t technically designed for. Duuuhhhhhhhjhh 🤪

Works perfectly, super cool

Let me start by saying that the title does specify that this is made for a 37MM launcher.
I tried to use this in my real M203 and it does not work due to the extractor rim thickness being to large. Nothing a simple lathe job wont fix, but I want those of you with real 40MM launcher to know that this is not a plug and play product for your 40MM launcher.

Otherwise this product is well machined, well priced and shipped fast. Would have been a 5/5 if it worked in my m203 out of the box.
