Quoted: In my previous post on looking for a Scocom mag block it was sugested to use Hahns mag block from Brownels? My question is will this work for a 40 cal and what mags would work Sten?? I believe OLY uses Uzi mags for their 40cal . will these work for this mag block?? Can you use 40cal in sten mags?? I had a Ruger which used the sam mag for 9mm and 40 cal? So I am just wondering anyone tried this sten to 40cal?? Thanks |
Yes, I use a Sten mag to run my .40. You have to tweak the magazines to get them to run smoothly. I run an SNS block and it doesn't need as much modification because it uses a feed ramp, unlike the Hahn, Socom, KKF block.
You should start by testing them as-is, sometimes they run just fine without modifying them. I trimmed off about 5-6 coils off of the springs and it makes it so much easier to load and it seems to feed better. Open up the feed lips with some pliers, but just a little so that the round sits higher, but doesn't pop out. With the springs cut, I can load 18-20 rounds in them, but they feed a lot better at 16 rounds. I use mostly JHP, so it was a bit of a trial and error to get them to feed reliably.
Buy a Sten Mag loader, it will make your life easier.You can grind down on the front of the magazine if the rounds are getting hung up. Picture below:
The follower can be modifed to better load/feed, but I've found that it really doesn't help too much.
