Brimstone Custom 10/22 Trigger

17 reviews Write a Review

(We are working on a video for installing these triggers, but until then all we have is this write up. If you're just buying the trigger, the Brimstone Trigger Fitting Guide is all you'll need. If you're buying the full trigger Kit, you'll ALSO need the Brimstone Trigger Kit Installation Guide

A lot of you guys DIY your own triggers, for which you have our support and whole-hearted encouragement! Seriously, we do a LOT of trigger jobs, it doesn't hurt our feelings any if you want to do your own... Or maybe you have drop in internals from another manufacturer, and the trigger pull now feels pretty good, but that horrible trigger and trigger return system are just crippling your otherwise stellar work. 

Well fear not. We have the solution for you. 

These triggers are machined from billet aluminum (not cast) and then individually Cerakoted in your choice of colors. Cerakote is an industry standard baked on ceramic coating which looks great, and will significantly outlast most CCW holster trends. Like, by a lot. 

But this trigger is so much more than bragging rights (billet not MIM'd yeah!) and cosmetics. We have dealt with a lot of aftermarket triggers over the years from a wide variety of sources, and it is surprising to us how many of them are radically undersized. They are often shiny and cheap, but they are also loose and, if anything, hurt the actual performance of the trigger. With these, every trigger will need to be fitted to the trigger housing. It's not significant, but it's enough that when it's done the trigger legitimately feels good under your finger. 

However, if you only install this trigger, but don't use the torsion spring, you are missing out on 75% of the point. This trigger is designed to accept a torsion spring, fitted on the left side of the trigger, to replace the current trigger return system. The factory plunger is actually drilled at an angle in relation to the rear face of the trigger, which means that as you press the trigger, that plunger both binds in it's hole, and slides across the rear face of the trigger. A great deal of the 'noise' you feel (particularly in the older aluminum housings) is from that factory trigger return system. 

To use this new torsion spring, you will have to drill and tap a small hole in the side of the trigger housing. A special set screw goes in there with a notch cut in it to accept one leg of the torsion spring. The spring mounts on the trigger itself, so there is literally no sliding or moving parts in this system; merely one spring flexing and relaxing. The factory trigger return hole is then drilled out and tapped as well, and an overtravel stop is installed in that hole. This looks infinitely cleaner than the common screw through the trigger blade option, and also leaves the trigger face clean and smooth under your finger. 

It's not especially complicated to fit the trigger and install the set screws, but you should know what you're getting into before you start. We will have some videos uploaded within a week or so, which will walk you through the process with tons of tips and tricks. 

These triggers are available in Standard Width, with all the same colors as our standard trigger work. The standard width option is actually slightly wider than the factory trigger, and because it is flat across it's face (rather than curved in both directions like the factory), it feels quite a bit wider. The Full Width trigger is ridiculously wide (we'll get some good pictures up soon), and so we recommend that unless you KNOW for a fact that you like really wide triggers, order the standard width. 

These are available in three kit options. The first is just the trigger. Use this one if, for whatever reason, you are planning on running it with the factory trigger return system. The next option is for the trigger with the new trigger return spring, it's set screw, and an overtravel set screw. This option assumes that you already have the required #21 drill and 10-32 tap. The final option has the trigger, trigger spring and screws, and the drill and tap. 

Thanks for looking, and stay tuned for more information, pictures, and videos as we move forward. And as always, don't hesitate to let us know if you have any questions or comments regarding this product!

    Spring pre-travel

    Posted by Michael Detore on Oct 5th 2022

    Without a doubt, a better mousetrap..I made my own spring with lighter gauge wire...I used a large hex tool to wrap the wire around...Pretravel decreased..The hex shape gripped the round part that is on the trigger....Just a thought..Redesign the trigger so the round part is now hex shape..Hex shape spring as well...Pretravel may be non existent..Pleased with my purchase

    One of the best flat shoe triggers I have used. Lowered pull by about 1/2 pound which I did not expect. Very smooth through entire pull.

    10/22 Trigger Kit

    Posted by Scott Szymanski on Dec 23rd 2020

    The trigger is a quality part. I bought the kit with the proper drill bit and tap. The included Allen wrench did not fit the set screws. I recieved two trigger springs. I don't know if one is a lighter spring or an extra. Installation was straightforward. My trigger housing did not need the lip removed and the trigger did not need to be filed to fit. It dropped right in as is. I only needed to file for clearance of the return spring. This is the first time I've worked on the 10/22. I watched videos and practiced disassembly/assembly to get familiar before the modification. I also modified the bolt release while I had it apart. My only recommendation is to include a dummy pin to ease assembly. I ended up making one. The trigger is definitely an improvement over stock. I don't have a trigger pull gauge so I can't say if it's lighter.

    I'd love to review the products, but I never received them. No responses to my emails from Brimstone.

    Best trigger

    Posted by Jerry on Aug 25th 2020

    With so many options for 10/22 triggers it’s hard to know which one to go with. With this trigger utilizing a torsion spring setup it is way better than stock. I just wish they gave you an option to buy one of those springs. Oh well.

    I've bought 3 trigger kits so far and all I can say is AMAZING trigger pull, feel and looks! For anyone that's not sure about the purchase or the fact you're worried about not installing correctly, I promise it's very easy and you won't be happier. Great product.
