There’s a reason the .22 Long Rifle has been around since 1887 — it works. Whether it’s running traplines, small game hunting, or taking care of nuisance critters, the cartridge has always had a place. It’s simple, effective, and widely available. Where it really stands out, though, is in training.
Whether you’re introducing a new shooter or refining your own fundamentals, the .22 offers a clean, distraction-free way to focus on what actually matters. Low recoil, minimal noise, and affordable ammunition mean more time behind the gun without developing bad habits or draining your bank account. That matters more than most people realize. Skill doesn’t come from a handful of perfect reps; it comes from repetition. And repetition requires time behind the gun.
For newer shooters, the lack of recoil removes a major barrier. It allows them to focus on grip, sight alignment, and trigger control without flinching or anticipating the shot. That’s where confidence starts to build, and confidence is what keeps people engaged. Once someone realizes they can control the gun and make consistent hits, everything else starts to fall into place.
For more experienced shooters, the .22 becomes a tool for refinement. It strips things back down and exposes flaws that larger calibers tend to mask. Poor trigger control, inconsistent grip, and sloppy follow-through all show up quickly when recoil isn’t there to hide them. It’s humbling in the best way possible. If you can run a .22 well, that skill transfers up. If you can’t, it’s going to show.
The .22 LR isn’t flashy, and it’s not meant to be. Historically, most .22 platforms leaned toward traditional hunting rifles, what most would think of as “grandad’s gun.” In the last decade or so, that’s started to shift. We’re now seeing modern rifles and pistol configurations that bring that same training value into a more current, adaptable platform. That matters, especially when you’re trying to mirror the controls, ergonomics, and handling characteristics of larger caliber systems.
At the end of the day, this build is about reps — clean, consistent repetitions that build real skill over time. Not speed for the sake of speed and not dumping rounds. Just deliberate, focused shooting.
Why the Retay RA1522 PST
For this project, I chose the Retay RA1522 PST. At just 4.75 pounds, it’s an excellent option for teaching both smaller-statured adults and younger shooters, without sacrificing functionality. Weight matters more than people think, especially when you’re trying to build good habits. A lighter platform is easier to control, easier to mount, and less fatiguing over time.
Out of the box, it comes equipped with adjustable polymer flip-up sights, a folding “not-a-stock” with a QD sling mount, and lightweight polymer upper and lower receivers. It ships with either a 10- or 25-round magazine and features an aluminum M-LOK handguard, full-length 1913 rail, thumb safety selector, and a faux suppressor. It’s a solid base to build out a training-focused PDW-style platform on.
What I was looking for here wasn’t just a .22; it was a trainer that mimics a more modern system and something that allows newer shooters to learn on a platform that feels familiar if they decide to transition later. At the same time, it needed to be simple and reliable enough to keep the focus on shooting, not troubleshooting.
Upgrades
The first change was removing the faux suppressor and replacing it with the Off Grid Suppressors Scorpious. Ranked #1 at the 2025 Thunderbeast Silencer Summit, it didn’t take long to understand why. At just under 2 ounces and built from 3D-printed titanium, it’s compact, lightweight, and requires no servicing.
One of the things I like to test with any .22 setup is how it handles subsonic ammunition. Typically, reliability becomes an issue fairly quickly. That wasn’t the case here. I ran roughly 500 rounds of subsonic .22 LR through this setup without a single malfunction. This was not your typical slow-paced plinking. I was moving and shooting multiple rapid shots, 25-round mag dumps, as well as the odd slow precision shot. That kind of consistency is uncommon for the caliber and speaks to both the platform and the suppressor. It’s one of those combinations that just works. Maybe it’s voodoo. I don’t know.
That level of reliability matters, especially when you’re using a platform as a teaching tool. The last thing you want is to spend more time clearing malfunctions than actually shooting. When the gun runs, the shooter learns. When it doesn’t, progress slows down.
Next, the factory’s flip-up sights were replaced with an Aimpoint ACRO. The original sights are perfectly serviceable, but on a shorter rail, the ACRO offers a more durable and streamlined solution. It’s a proven optic with a track record of holding zero under hard use, and that’s important here. This isn’t a safe queen; it’s a training tool that’s going to see real use.
A red dot also simplifies the learning process for new shooters. Instead of managing sight alignment and sight picture simultaneously, they can focus on placing the dot where they want the round to go and pressing the trigger cleanly. It’s not a shortcut; it’s a way to build confidence early and layer in more complexity later.
To round things out, the M-LOK handguard was set up with a True North Concepts QD sling mount and a ZERO-8 V2 K-length hand stop. The QD mount allows for proper sling placement, making transitions, movement, and overall weapon handling more efficient. The hand stop adds control without taking up unnecessary space, giving the shooter a consistent index point without overcomplicating the setup.
Nothing on this build is there for the sake of appearance. Every addition serves a purpose, and that purpose is to support training.
Rattle Can Camo
I’ve always had an appreciation for a good rattle-can paint job on my guns. At the end of the day, these are tools, and I treat them as such. I know there are plenty of people who can’t stand the idea of a gun not looking factory new, and I understand, but I don’t agree with it.
Tools are meant to be used. And part of that use is understanding how they perform across different conditions, terrain, and levels of stress. A pristine finish doesn’t tell you anything. Wear does. So, what does that have to do with paint?
Depending on where you are and what you’re doing, your gun can easily become the most noticeable thing in your environment. Picture moving through the woods in full camouflage, making a conscious effort to keep your visual signature low, then hanging a factory-finished rifle off your sling. Most factory finishes, regardless of color, have some level of sheen. That sheen catches light, and light draws attention.
That’s a problem.
A simple paint job fixes that. It breaks up the outline, reduces shine, and helps the gun blend into the environment instead of standing out against it. It’s not complicated, and it doesn’t need to be permanent.
My go-to is Rust-Oleum Camouflage spray paint. It’s easy to work with, holds up well, and most importantly, it offers a true matte finish. The range of colors makes it easy to tailor your setup to the environment you’re operating in, whether that’s woods, open terrain, or something in between.
I’ve used it on rifles, footwear, packs, and even the base layer of a ghillie suit. It’s not about making something look cool; it’s about reducing visibility and making your equipment work better in the environment you’re in.
And if it wears off? Good. That just means the tool is being used.
Closing Thoughts
This build isn’t about chasing performance numbers or creating something flashy. Instead, it’s about creating a tool that supports training — something reliable, approachable, and effective.
The .22 LR has always been a gateway into shooting, but it’s more than that. It’s a foundation. It allows new shooters to build confidence and experienced shooters to refine their skills. Paired with the right platform and thoughtful upgrades, it becomes one of the most effective training tools you can have. At the end of the day, it comes back to reps — clean, consistent repetitions. The kind that build real skill over time.
