Beretta Neos Complete Educational Guide and 'homebrew' Action/Trigger Job by hexidismal
|Important Note: In regard to Beretta Neos Recall of 2010
This guide was made several (4 maybe ?) years prior to the safety mecahanism related recall of Neos pistols. It was brought to my attention that due to the the new hardware replaced on recalled guns, this guide may not apply. I have no experience with a post-recall gun, and therefore can not offer any insight on what alteration to this guide might be required. Please note this if you have a recalled or post recall manufactued Neos.

|Part 1 Personal Introduction: Why I'm making this guide.
I may make future revisions to this guide as I get suggestions and comments, add photos, etc. I can be found on firearms related forums TheHighRoad.org and TheFiringLine.com (among others) under the nickname hexidismal . Feel free to contact me with questions and comments there.
So.. I decided that I wanted to do an action job on my Beretta Neos .22lr pistol. Let me first make it clear that I am not a professional gunsmith. I am however an amateur of many years, familiar enough with firearms and their respective mechanics, to be perfectly comfortable with the required processes to complete this project (it comes out great at the end.. I promise !). I had a very difficult time finding information before starting out. In fact I was not even able to find an exploded view of the Neos internals online. There is a already a tutorial out there of a Neos trigger job. I believe it was originally made by someone over on rimfirecentral. That was my initial inspiration to do the job in the first place. BUT.. while that tutorial does have some very useful data, it doesn't really tell you much of the Hows and Whys. Also, I'm going to be taking things a few minor steps further here with the action job. With this document I hope to fill the void of information on working with this pistol, AND put forth some ideas of my own which I've seen no prior mention of. Because the Neos is mechanically a fairly simple pistol, I thought this would be a great opportunity to both provide the most complete tutorial for those looking to do the work, while also hopefully giving an interesting look into the Hows and Whys of the pistol's internal workings for everyone else.
One thing I HAVE to say here. If you are not fully comfortable with detail stripping your firearm, and/or do not have the proper tools to do it correctly and safely, please to not attempt this action job. It is a lot of work, and replacement parts may or may not be available. I won't be held responsible for a massive influx of Neos pistols requiring repair at your local gunsmiths... although if that does happen.. I want my cut.. hehe-JT
|Part 2 Introduction to the Beretta Neos: Why choose this gun for this guide ?
The Neos is a single action semi-auto pistol chambered in .22lr. It is a very modular design, allowing for very simple changing of separately purchased barrels in various lengths. Each barrel has a full length optics mounting rail with many positions available for all sorts of optics options. In my opinion it is a very well built and thought out pistol design, especially considering its reasonably affordable price point. The one negative issue you will see mentioned on the forums is that the trigger is.. not horrid maybe, but not great either. It comes from the factory a bit on the heavy side, and with some trigger creep. This guide will solve all that.. no, really ! As stated above, the relative simplicity of the internal mechanics makes it an optimal gun for this guide.
So, here we have the gun we are starting out with. My Neos 6 Standard model. Cost: About $200. It should be noted here that this guide applies only to the standard model Neos and NOT to the adjustable trigger DLX models. I haven't had the opportunity to see the internals of the DLX model, and I therefore I can't discuss the differences between that and the standard model.
Part 3 - Disassembly: Let's strip.. I'll tell you How and Why the gun works later.|
I was divided on whether to put this section or section 4 "How the Neos works" first in this guide. Since that section requires photos showing connection points between internals though, I thought maybe we'd best see those parts come off in the right order first to get you more familiar with them. As a side note to the more seasoned veterans, please understand this guide is for everyone (even people who don't own a Neos). Feel free to skip the hand holding parts at your leisure.. hehe
Here is a picture of the gun completely stripped, with the individual assemblies bagged separately (some pins look similar)
Step 1: Make sure the gun is unloaded and the magazine removed. Obvious I know, but it had to be said.
Make sure you are holding the receiver vertical upon complete removal of the screw, as the safety plunger/sear spring housing is held loose underneath. The spring is not heavily loaded, it wont pop out at you, just be aware it will fall out. Now is a good time to note its relation to the safety lever and the sear (More about that in section 4). Pull out the sear spring housing. It is two halves, one sliding into the other and it contains the sear spring in the middle. If you just get the top half and you see a spring there, it will fall out when you turn it over. Also note that the trigger bar will spring forward with the assembly removed.
Step 5: Remove the pin from the magazine catch from the top down. After frustrating you horribly with the last two steps, Beretta has decided to give you a break here and even provide you with a grooved guide for your punch. Isn't that nice of them ? The catch is clearly spring loaded. Not too strongly, but be careful not to let it pop out fast
Step 6: With the mag catch pin removed, you may now remove the trigger pin. Do this from the inside (under the mag catch) to avoid any possible cosmetic damage to the gun. You may now remove the trigger, trigger bar, and trigger bar spring. (these are the goodies we want)
The right side safety lever has a small button which can be depressed. With this pushed in, you can slide the safety lever forward. The button itself will also come out, and is a tiny and easy to lose part. Now this next part is slightly tricky. Once the left side safely lever, and the firing pin/sear assembly have been removed, you can slide the right hand safety lever and full safety assembly out of the gun. WARNING: There is a very tiny spring and plastic nub contained within that will fire out quickly if you allow it to do so. Mine did, and I was incredibly lucky to find it so easily 15 feet away in a large and messy room. This part keeps the safety locked in up or down position. Note from the photo where it will be coming from. Its also an annoying spring to get loaded back in. Now that you've seen it, don't bother.
There is also the ejector block seated lower in front of the trigger bar/sear assembly. It has its own pin, but don't bother as there is no reason to remove it.
|Part 4 - How the Neos works: Why are we making the changes were going to make ?
Although I'll show a few minor extras that may or may not have any discernable effect, the really important things affecting trigger crispness and pull weight are #1: the engagement between the sear and firing pin, and #2 the sear spring power. Here I'm going to show you how the gun fires, any why the improvements should have the desired effect. For this entire section you may want to refer to the diagram for a better understanding.
Ok, so now we know the parts. So, let's see how they work together and how the gun fires. I've made a rough diagram. The parts are not in perfectly realistic proportion to one another, but it's close enough and I think it get's the point across fairly well.
|Part 5 - The action work: Reducing pull weight, Creating a crisp break with no creep, and additional "grit" smoothing.
So here's where we finally get to start the work. The above sections we're intended for general information and education for everybody. Now that I've gotten that out of the way. I'm going to cut down on lengthy descriptions and explanations a bit here. You know what basically what needs to get done.
|Part 6 Wrap Up:
So, after much experimentation, and many reassemblies to test various springs and prefect the polished surfaces... My Neos now has gone from between a 5.5 to 6 pound trigger, all the way down to just around 1.7 pounds. It also has eliminated any trigger creep and breaks extremely crisp. Like I promised near the beginning, it came out great !
When you're happy with the action, use some thread locker on the Firing Pin/Sear Housing Screw. I don't think you'll want to use the strong red stuff. That screw is in there far and tight, and you may want to open it up again sometime. (Possibly to replace the sear spring)
This took a lot of time and effort so I hope you learned something and enjoyed this Neos tutorial/guide. Once again feel free to contact me on the forums with any questions or comments Thanks for reading, and I wish you good luck on your own action work.
