Hey Matt, with interest in the new 9mm M-11A1 CF-W bolt and corresponding GG uppers, do you have a photo of that opened up M-11 upper and an OEM bolt?

I never took pics of the CF-W bolt in a short M11/9 upper.

So I'm clear, you opened up the rear of the ejection port on that particular upper for the .22LR conversion? How much? 1/4"?

*Never mind. I just now saw your response below the photo. I'm still interested in how far back you cut the ejection port and if you have any photos of an M-11 bolt showing the gap. Thanks!

Here is a pic of a OEM 380 bolt in a short M11/9 upper.

The ejection port for my M-11A1/22 upper was opened .2" to the rear. The pic of the 22 kit and the 180 drum I posted earlier in the this thread shows what the opened ejection port looks like with the 22 kit installed.

I'm wondering how Bazooka Bros figured out to get cartridges to feed from the pan upwards through the feed tower?

It is an even older design than Bazooka Bros. Here is one of the Harrissr plates I adapted for the 15-22. You can see how it works. It required loose dummy plastic rounds to push from inside the drum. I used the Blackdog Machine dummy rounds because they have a silicone tie that keeps the dummy rounds together. It was easier and faster to reload that way.

Member Shattered has an older version for his Thompson 22 kit.

Thanks Matt. I've got a cut down M-11/9 upper that was used for some of the initial testing on the new W bolt before transitioning to the OEM M-11A1 bolt with a 9mm barrel. Much to my surprise, I didn't experience a single piece of 9mm brass being caught in the smaller port. Still, it seems use to enlarge the original port size just slightly if it doesn't result in an unsightly bolt gap. I'm interested in seeing the bolt gap in the opened up ejection port on the original M-11A1 upper with an OEM size bolt.

Now, to prevent this thread from being derailed, I'll share my .22LR experience.

I've seen, handled, and shot Kermit, Tod's .22 drum fed creation. It's somewhat crude construction didn't prevent it from excellent functioning. The concept is sound.
While waiting for Craig Wheatley's AM–15 upper to be produced, I purchased a Bazooka Brothers adapter. Despite my best effort's I could never get it to shoot more than 15 to 20 rounds before it stuffed up. Even a trip back to the manufacturer for an upgraded defend tower didn't the problem. They blamed it on my 22 conversion which was total bunk. The last time I took the adapter out I got frustrated very quickly and switched to 30 round magazines. After running 14 street bags without a single malfunction I sold the Bazooka Brothers adapter and never looked back.

Shortly after that, the AM-15 uppers began shipping. At least four of us here in town received them at about the same time and we all had problems. One owners pinned his feed block in the same way that Val pins feed blocks on the American 180. This seemed to provide better results. One of the owners returned his for service several times and they eventually refunded his money. Like the Bazooka Brother adapter, I sold my AM-15 upper, drums, wonders, etc. and I have no regrets.

For the life of me, I don't know why I never purchased a Lake Side .22 belt fed upper. Well actually I do. Two of my friends here in town purchased them for thir M-16s and they didn't run anything like the 1,000 round dump video that was posted in this thread.

At some point I asked one of my buddies to kick me square in the nuts if I ever so much as considered buying another .22 conversion. He didn't find out about me buying a Lage M-11/.22 conversion which is probably my favorite conversion of all time. Having said that, I had a .22 conversion for my Vector Uzi that ran ver well from day one, and after considerable tinkering, My Ciener style. 22 conversion for the M-16 ran extremely well with 30 round stick mags but it was very very fast.

Today, I'm down to the Lage .22 conversion and I hope I'm done. If I need another .22, I'll buy one that's built for that caliber from the ground up.

I agree about 22 select fire SMG being finicky, but I love the challenge. There are days when I want to swear off buying more 22 stuff but then.... I have great days too. It's funny but it's a love/hate thing.

I wish I could post a pic of the OEM 380 bolt in the 380 upper with the .2" opened ejection port but I sold my M11A1 and all of my M-11A1/22 uppers.

If those people who have my old 22 uppers want to post pics with the 380 bolt in the upper, that would be nice for Tom.

10/22 GSG 110 round drums

Has anybody thought about making some of the 10/22 GSG 110 round drums work in a Lage 22 kit? It seems like you could make a tower out of a Black dog machine Lage 22 mag. You could run it in the Max 11 and maybe with a mag adapter with a Max31 upper too.

I don't mind loading an AM180 drum. It's easy because there is not tension on the drum when loading. It just takes awhile to load 200 rounds.

The GSG drum is the biggest PITA to load. I only tested the drum 2 times before I put the OEM tower back on a sold it.

I was talking to one of our club member in IAWCA (Idaho Automatic Collectors Association http://iawca.org/) and he was talking about converting his Max-31 or something like it to hole Ruger 10/22 magazines. That way you have a reliable magazine that you could potentially have a 110 round capacity. I thought it was a very appealing idea.
