New Member - 4MM M20 Question


#1

Hi, I’m new to the board. I’m mostly a C&R semi-auto collector, and a recent purchase brings me here. I picked up a 4MM barrel for an Astra 300 that looks to take 4MM M20 cartridges with an adapter of some sort. I found a thread on this site that seems to picture what I have: viewtopic.php?f=8&t=6647&start=45

Here are photos, including on showing what I believe it the adapter cartridge (from this site).

Am I correct, and does anyone know where I could purchase a few of the adapter cartridges?

Thank you,

ArmoryRacks,

Welcome to the forum.

Adaptor cartridges are not my area of collecting but as far as finding some of the 4mm rounds you are after, below is a link to a listing of places to purchase collectable cartridges:

The 4mm Ubungsmuition M.20 is briefly discussed on the forum here: viewtopic.php?f=8&t=10740

Good luck!
