There are tons of posts and articles on the interwebs about what the best 20+ capacity magazine is for a particular .22LR host.  But I haven't found any such that then compare these magazines against one another to determine which one is just the absolute best.  

I know, seems a bit odd, because why would you care if the mags for a 10/22 are better than those for your TX22, given that they are not interchangeable?

But on the other hand, things have come a long way since the days that we had limited options besides the old 10/22.  And let's face it, mags have seen improvements - case in point the TX22, previously 10 rounds was about all that you would in a 22LR pistol....

Thus I ask thee, great oracle of ARFCOM, what are some of the best 20+ capacity 22LR mags out there?

I've personally witnessed hundreds of thousands of 22 rounds being sent downrange.  While the standard 10/22 box mag was the most common, I don't think I've ever seen a problem with a BX25.

I had one of my BX22 25rd mags fail me a couple of days ago. The gun was clean, and the magazine was clean and maintained. The front of the bullets aren't rising as high as they're supposed to. I swapped out to my other BX22 mag, and it runs flawlessly. I'm sure when I get the "bad?" one unloaded, I'll be able to fixed it easily. I liked the old, 1980s-1990s Butler Creek mags. They were trouble free, until the late 90s and they started having issues. They fixed that in the early 2000s. Ram Line had good ones back in the day too.

My 25 round AR22 Black Dog mags have been pretty close to 100% reliable.

I have 6, going on 25yrs now. Tens of thousands of rounds of Fed bulk. I can't recall a single problem. The McFadden loader makes it a breeze to keep blastin'.

Black Dog 50 round drums have worked fantastic in my M16 22lr uppers.

^ lol



the older BX-25 mags have worked well for me
the newer ones have some issues here & there.

i am in process of following this ARF guide

Best I run are S&W m&p 15-22 mags.  I don't own a m&p 15-22, but I run'm in my 22lr AR.

I don't think I have ever seen a bx25 that worked.

15-22 has worked though.

For most of my uses the 10 round 10/22 mags are still the most reliable option

I can see with the proliferation of FRT ‘s the need for large caps

I couldn’t get my 15/22 S&W reliable enough for my tastes with the factory mags.

The BX-25’s were fine in several 10/22’s I had about 10 years ago. Sold all off for something else since I didn’t feel the need for all the 22 stuff. As usual I came around the circle and am now doing a lot of 22 rimfire stuff, and rebought BX-25’s and 15’s.
First try with a new BX-25 was jam city ( in clean wells lubed gun reliable otherwise)
Took mag home loaded with 25 sat for a couple weeks now works fine.

For me
AR22  is Blackdog mags
1022  is the Ruger BX

I’ve never had an issue with either M&P15-22 or BX25 magazines.

We have a fondness for Blackdog. They just got a lot right on that design.

Same. My Blackdog AR 22 and CMMG AR 22 mags (same design) are almost 20 yrs old and never an issue after tens of thousands of rds. They are dirt cheap too, like $10 sometimes. All mine are the polymer feed lips and none have cracked or worn out.  The only con is they don't have LRHO, but I'm not picky about that.

Ruger BX works 100%, but are a PIA to load and unload, even with the Mag Lula loading tool.

That guy took my answer.

I find them a bit fiddly to load, but the several I have all work perfectly.


I use them with a BCA .22 AR upper that is just a hoot.
