Three to be exact.
I used Brownell magazine tube bodies and MagPul Ranger Pul Floor plates.
No instructions were included with the goodies and it had me stumped until I went to CMMG website to get it sorted out.
The braided wire springs are installed to the floorplate upside down from how a conventional spring is installed to a plastic follower.
I clipped the bottom big loop onto the floorplate instead of the small top loop and everything then dropped into place, literally.
You don't have to wrestle these floorplates into place like the MagPul or USGI green followers, they just fall down the magazine tube.
Everything popped together without issue after that.
The MagPul floorplates take up enough space that only 29 rounds can be loaded but that isn't a big deal to me.
If you use standard floorplates, 30 rounds load up without issue.
The cartridges snapped into place and these followers do make it sound like I am loading an AK magazine.
I fired 120 rounds through one of my AR rifles, two magazines on slow deliberate fire and two magazines as fast as I could pull the trigger, everything worked fine.
Magazines slid into place smoothly and ejected from the well without having to tug on them.
Bolt locked back every time. Happy, happy, joy, joy.
Short test so far, I know, but I just got these things together, It will get worse for them I assure you.
I am now going to run some torture tests on this set up to see if they offer any real practical advantage.
Big downside, if these don't offer any real advantage, is the price.
Using new componenets these magazines averaged out to about $26.50 each, ouch.
Mind you my intended purpose for these magazines are three gun match dedicated. I f they offer advantages great, I will make up six more, if they don't, I will go back to my standard Brownell 30 rounders.
We'll see.
