Hey All,

Went to the range the other day to finally test my DB Alloy build. Before I ever got to the shooting phase, I had issues with the printed Sten mags, so I decided to buy a few surplus mags from Atlantic Firearms. So I got my mags, polished them up, put a little lube around the follower and what not. The mags work fine outside the gun itself.

Got to the range, loaded up my mags, and when I pulled the charging handle, it seems like it is double feeding. The bolt charges two bullets instead of the one. Whatever, tried another mag, same thing. I'm thinking this is on the mags.

Any suggestions?

Yes I have printed the adapters.

Have not yet tried with snap caps as I have none in 9mm but will test soon.
