CMMG & EndoMag 9mm PMAG AR9 Conversion Kits

See comment below 🇺🇸

Love the vids the detail and small item reviews. Keep it up

CMMG says you need a "modified" upper to run the RDB bolt and barrel reliably, how "modified" is it exactly?

0:27 that laugh is priceless 🥰

I have both mags but the cmmg mag won't chamber a hollow point. Anyone else have this problem?

You should call Mean arms..they will send you a PDF file on how you are supposed to trim back the part that is getting " beat up"

I’m jumping on 4 of the CMMG’s. I’ll run my Banshee 9 upper on my PWS SBR lower.

So in other words you can't clear the Endomag system without having a mag which means you basically can't fire a round on a mag, eject it and then safely clear the weapon and you'd have to store it with a live round in the chamber. That's really dumb design because it means you'd have to have an extra one of their mags laying around empty to clear the chamber if you were at the range and stopped before you finished the inserted mag.

CMMG makes such great quality and innovative systems! I still have a mil-spec trigger in the first AR I built and I shoot that rifle at 100, 200 and 300 yards with close to sub-MOA results on the regular after probably 2500 rounds through it. I'm definitely going with their radial blowback 9mm system.

Great video!

also aren't the cmmg mags only compatible with their uppers?

not to be a prick but you just showed the endo mag removed will not eject the round. and followed with ejecting a round with the cmmg mag installed not removed?

Thank you for clearing that up, I have full confidence in buying a CMMG conversion now.

Ur comparing two different actions

The eyes veering off to make sure the precious 9mm does not roll off the deck into the water. The subtle cold panic

Is there a video for your 9 mm AR build if not would you make one?

I’m confused do all AR 9mm bolts used with blow back carrier not have a extractors in them? I always figured they worked like a standard bolt with a spring loaded ejector!!!

6:23 where's the cut for 5 rounds (canada)?? 🙁

All that precious ammo…

That’s the sound of freedom there!!

strange your vids suddenly dont show up in my feed. i have to actually click on your channel to see of anything is loaded. notifications are on as well. idk. must be a sensor thing? hmmmm

Mike, doesn't Mean Arms make the cmmg kit?

Interesting, but our country is on the edge of chaos. Picture bloody Kansas on a huge scale. This kind of stuff is for collectors and hobbyists. Stick to one military rifle caliber.

Mike stay away from that idiot in AZ. He’s a rookie who will just bring you down. 👎

Mike, I was ticked to hear about your Joe Biden gun control video being pulled down. I saw that Buffman R.A.N.G.E re-uploaded it earlier today. I have it saved as well and can release it on my small channel as well (if needed) but wouldn't do so without your permission of course. I have it saved exactly as you had it on your channel. If that is needed please let me know, it's important that this information get out with such a vital election being so close. Thank you for all you do Mike 🇺🇸

Why does YouTube keep unsubing me from your channel… sob

What GNG, I would buy an Auto Lower, but Washington State won’t them into state. I heard some people keep them in arms rooms in Oregon and shoot them there

I went the mean arms route 3 pack first lasted maybe 100 rounds until bolt snagged it. Second lasted almost a 1000 with modifications and twisting, took a dump when I started shooting faster and heating it up snagged the bolt again. 3rd sitting in the drawer quickly ordered a dedicated 9mm lower and a stern defense adapter both shoot flawless no hiccups at all.

I had the mean arms and never could get it to work. My bolt just kept getting caught in the ejector total garbage. Cool idea though

Fuq the FATD right in the asshole. Nice pew pew!

I have over 1k rounds through one of my endomags in a gen 4 psa 9mm 4" upper with no issues. Also the top of my mag doesn't look chewed up like yours did.

Oh that third position goodness…

I have a couple of the CMMG made mags (I didn't convert them) haven't put many rounds through them but I do like them a lot. The downside (this is probably mentioned in the video) Is that the lower is limited to 9mm only using this method. They feel awesome though.

Good thing the Endo Mags come with a life time warranty!

I have some of the EndoMag inserts. I'm also skeptical of the plastic extractor. But so far, so good. I still check them constantly.

Just took mine out today, she was a virgin and a nice virgin that did everything it was made to do, no hickups FTF or FTE, sadly mine is not SBR’d not yet anyways 😅 great video and review as always sir 🍻🙌🏽💯

I don't recommend these at all. I pre-ordered the CMMG Variant of the Mean Arms Endomags coming on 2 years ago now. I've put thousands of rounds through them and basically gave their team free troubleshooting. I don't recommend them at all due to spring durability. The case head of 9mm brass is longer than .223/5.56. This causes the spring (which is already truncated to allow room for the feed ramp area) to be massively compressed all the time. You hit solid spring height very easily which accelerates the wear on the spring. I've had some that gotten so worn already that they will cause malfunctions.

It's a good gimmick if you got a registered machine gun because you can easily convert your 5.56 set up to run basically like a MP5 with the CMMG upper. But beyond that I would pass. I tried using these to compete with a SBR in USPSA and got so frustrated that I ended up actually buying a stripped CMMG Glock pattern lower and SBRing it. It runs like a champ with glock mags as it was originally designed from the start that way.
