Tuning Mag/Gun for Slug Feeding

Recommended Posts

  • 3 weeks later...

The problem persists even after tweaking the wings a little bit.  I bent both wings a little left.  Even happens with AA shells.


Can it be a problem with the SAS lower and the second gen mags?  My gen 1 mags run just fine in the SAS lower.

I can only tell a difference on the body and follower.  The Gen 1 have a collar stop and the Gen 2 are a taper stop.  Plus the black and orange followers have a different front profile.


From video 3, I guess I will just adjust the wings more.

Ive had similar and a tweak on the right hand wing helps

Ive also chamfered the right side of the barrel a tiny bit.

Used to hang up about 1 in 50.


Hopefully sorted now. I hand cycled a couple of mags no problem.


As also mentioned see if you can fund ammo with a good roll crimp.
