I'm working on a trade and someone offered me an Anderson "multi" lower. I checked out their sight to see if they're regular AR lowers, but can you confirm? What's "multi" about them?
Because the lower can be used for "multi" calibers. 5.56/223, 300BLK, 6.8 SPC, 7.62x39, 6.5 Grendel, 9mm, etc hence the designation of "multi" on the side.I'm working on a trade and someone offered me an Anderson "multi" lower.

Anderson has some marked .223 and some marked multi. I don't know if it makes a difference or not, but most companies mark them multi.
Take a look at a S&W. M&P. 15, I have a pair of them with NO CALIBER markings of any kind.......I was mighty surprised when I realized that when logging them into my boundbookAs I understood thngs - the lower is marked with the chambering of the firearm because that was/is the law of the land. Given the modular nature of the AR platform, the BATF allows the manufacturers to use the phrase multi instead of a specific chambering designation.
At least that is the oral history that I was told, many years ago.
The only real thing to note is what Browning touched on: The grip screw hole is not tapped all the way into the receiver. That's fine if you use an anderson or magpul grip screw, but regular AR screws are too long.
How many Gen I Anderson lowers were put out in comparison with the Gen II's? (That's a real question, not a leading one). Just took a look online and I can't find a single one."...a lower is a lower is a lower."
Can't agree, particularly where Anderson Gen. I lowers are concerned. Many I have seen were out of spec in critical areas. Compare one side by side with a top shelf offering like Aero Precision's and you will immediately see the difference.
The Anderson Gen. II lower with integral trigger guard seems to be better. Perhaps their QC will hold up with the new generation.

If the grip screw hole is tapped all the way through, you run the risk of a too-long grip screw intruding into the fire control cavity, and impinging on the trigger. This could be a serious safety issue. (It could reduce trigger engagement with the hammer -- the hammer could slip off the sear portion of the trigger.) It appears, therefore, that Anderson is making their lowers this way for a reason. Kudos to them. (Think about it -- tapping the hole all the way through would actually be easier.)
