EndoMags for 9mm in 5.56 lower
Who's used them? Good vs. evil?

Please just opinions on the use, I have a 9mm glock PCC already, just wondering if it's worth getting another upper to make my .223/5.56 lower work too.

I have 6 and all function well. I did have to sort though some Gen2 Pmags to find the ones that allowed the 9mm follower to move with the least resistance, but once that was resolved (just me being picky) I've not had a 9mm upper that wouldn't run with them, even in FA.

Also, be aware with Endomags the ejector is on the mag. So if you do not retract the bolt with a mag in, the round is not ejected. Easy to adapt to and routine safety practices keep you safe. But, a different clearing procedure if you do not shoot the mag dry.

Perfect, thanks! This was just going to be for a range "toy" not for competition/HD. I just didn't want a piece of crap for the range though.

I have 3 endo conversions. First two worked great. Third one probably works fine but the extractor on my Banshee upper broke so I never got to try it.
I didn't bother to fix the extractor. They did send me the part. My Banshee lower for Glock mags hit production yesterday, so I'll probably get around to fixing it soon and off loading the Endo conversions. But when I used them, they worked fine.

I have 3 of the CMMG branded variety than I'm using in a homebuilt carbine with a CMMG RDB barrel and bolt. All have been flawless and I'm very happy with them. I much prefer this solution to the Glock mag lower that I had before.

I have 9. I don't run them all that much since I have glock, sig and colt lowers. But when I want to test an ar lower with some change (like trigger) I run them since I have way more 9 ammo than 5.56. I have had no issues. And I wish Chowser would fix that extractor. I hate stuff of mine that's broken and his stuff is now starting to impact me mentally Smile

My three just work as intended.
The ejector being in the mag isn't a big deal to me and it's kinda handy when using a snap cap for dry firing as it doesn't chuck the cap when resetting.
Being Magpul mags they fit in the mag carriers on my belt as well.

I have a half dozen or so that I don’t need. PM me if you’d like, I’ll make you a deal.

“EndoMag” sounded medical, so I did a search:

Interesting.

Just don’t ask about using an endoscope on an AR15. Wink

Thanks! I'm doing some thinking over .300 Blackout and sent you an email.

Got an email with tracking info for my Banshee lower so I will fix the extractor today when I get to work tonight.

After it broke, I just threw the upper and endo mags in the armory at work. Hoping I still have the parts somewhere to convert my endo mags back to regular Pmags.

Filling out my eform 1 now. Once my FFL confirms the serial number, I'll send off for the sbr stamp.
