This is my Ruger American Ranch rifle in .556 NATO, it takes AR15 Magpul magazines and has a 1/2-28 threaded barrel, same as the AR15. It’s pictured with a ten round mag.

Not as pretty as the OP’s rifle, but she’s a shooter. I have a direct thread can coming for it, should be here next week.
For comparison with my AR.

Running a GemTech on my Remington 700, it has the quick mount adaptor. Push it on, compress a spring plate and rotate 90° its on.
It’s an older model and weights 1.88 lbs. It’s a beast but is very quiet with subs. Have to give the elevation turret a few clicks when it’s on.

These are my two .22LR cans, one is a Tac Solutions and the other is an erector by Q.

The erector is nice because it comes in pieces so you can take it apart to clean it and rotate the sections front to back. You can also make it as long or short as you want. The erector is on the top pistol.
