Beretta Neos magazines for Colt Challenger

[SRV1]

Well I went out and bought a Beretta Neos magazine. Being that I have a Challenger, the mag release is on the bottom of the gun. All I had to do is grind down part of the base pad and sand down part of the follower, make sure you have a little play between the latch and the magazine. You do not want it tight. The knob on the magazine did not have to be shortened. It had plenty of room in the magwell/grip. Next step is to see how it works when firing it. This is similar to this thread: https://www.rimfirecentral.com/forums....php?p=4704329

Well I forgot this is a blowback design so I really could not manually cycle the rounds. What was happening on the last round?

The rim of the last round would seem to hang up between the rear of the follower and mag but when closed up a little worked fine. If you want I can post some pics of the two mods if you run into that problem.

[SRV1]

Sure, post up some pictures.

I'll do some pics, If your chamber and and bolt are clean You should be able to work the bolt by hand [ clean ] Chamber and test as you go. I think you have done your research so steady now

Actually, blowback as you know is what assists in extracting the spent round. I can manually cycle the rounds but not all will extract. Of course every firearm is different so yours may manually cycle fine.

James your doing great, With loaded mag get first round to cycle when that's done work on the last round by mods to back of follower

Still waiting to shoot it. Maybe tomorrow or Sunday I hope. I have a couple of other 22's that I have to test fire because I had problems with them.

Here are some more pictures. I forgot to mention that I have another magazine which is a 2nd series Woodsman magazine (C). The other is a genuine Colt replacement which is a late 3rd series (F): http://www.colt22.com/wmmagazine.html

From left to right, 2nd series Woodsman, late 3rd series and Beretta Neos


Notice the notch on the 2nd series Woodsman for the magazine release




Top to bottom, Neos, 2nd series, 3rd series


Here are the base pads of the Colt magazines, left is 2nd series and right is late 3rd series


I mentioned above that you need to have some play at the bottom of the basepad for the Neos magazine. The reason why is that the basepad acts as a stop for the magazine to limit up travel. The 3rd series magazine is a piece of formed metal which can get bent. Depending how it gets bent will cause the slide not to close. Same thing with the Neos magazine. The little notch on the bottom of the magwell is what the basepads sits into. If you look at the pictures, you can see how critical the dimension is:

2nd series


3rd series


Neos


Notice the Neos magazine basepad. It does not sit flush in the notch. This is the reason why you need some "slop" between the basepad and the magazine latch. If you did not have any clearance, the magazine will sit up in the magwell and then hit the bottom of the slide because the latch will be pushing it up. The 2nd series is a piece of machine steel so bending that is a lot harder to do. You will have to spread out the feed lips on the Neos magazine and do some fine tuning. Basepads of the 3rd series Colt magazine will fit in the Neos magazine but it is tight.

Thanks James for sharing your results and taking the time take and post pics, keep us posted on test firing with the conversion

Had a chance to shoot my guns today. Let me tell you the 22 Remington Jet is loud as hell and it makes a fireball that would make a Mosin Nagant jealous! That being said, the Neos magazine worked flawlessly! I ran Remington lead round nosed (CMP training ammo) and some CCI mini mag. No issues at all. Seems like I now have access to affordable magazines.

Just thought I would post up. The magazines are still working flawlessly.
