High speed, low drag skeet shooting.
If you're going through hell, keep going.
A .410 is only practical and somewhat-affordable to feed if you're running .45 Colt ammo through it, so I've got to wonder how this would do on that diet. But then I'm picturing black powder .45 rounds because how else are you going to make that much smoke out of an AR?
Brilliant IF, I can strip all the parts out and install them in an SLR or MS upper. Can I?
Why can't we hunt with this in Canada? Keep in mind every province has it's own rules for non-migratory.
100% depends if it can go on a non-restricted lower. If yes, then brilliant. If not, then I'm not in the least bit interested. Don't need a .410 for a range toy.
