Yes the short version with drums would be less comfortable. That's why I will use the old one for drums. You can add an attachment to help.
I like using stick mags over drums and use a suppressor.
One thing I've learned over the years is if a new upper comes out get it.
Especially the quality of this upper.
Thanks!! Like you, I was planning to shoot using a suppressor which is why I originally liked the idea of a shortened 10/31. The short length is exactly what I was worried about. What sort of attachment do you think would work best? I was planning to just use a regular vertical foregrip.
I'd love to use stick mags, but I think I got into the game too late. Zmags are gone and coffins are insane. I was able to get a couple of good deals on drums though so I have about 10 or so of those. I also considered doing the old-school route and converting Sten mags, but the conversion tabs are long gone too. I recall one guy used a couple set screws that he filed flat on the sides for the conversion and he said that worked, but that seems a little unreliable.
Also is that a FAL stock? That looks incredible!
