Austrian STG-58 is metric is it not? DSA has a specific STG-58 receiver
Yep... it is, my bad. Just wanted to make sure it wasn't inch pattern. See, I'm pretty new to these two.
Any reason type 1 over type 2? They are very similar but the rear of the type 2 is a tad stronger. Not that it matters in a semi gun but with earlier versions of the type 1 full autos were cracking in the rear. that's the reason the type 2 was introduced.
