The new MCA-22 Rimfire Chassis from LUTH-AR is a lightweight and simple chassis designed to fit any shooter. I can’t tell you how many guns growing up didn’t fit my length of pull, my cheek weld, or were comfortable to grip. Similarly, as an adult, I find it extremely difficult to find shotguns or rifles that fit me comfortably and give me a clear line of sight for whatever sights or reticle I’m using. Mark Roth with Roth Performance solved this issue with his Modular Chassis Assembly designed for semi-auto .22LR rimfire actions and barrels, with inspiration from LUTH-AR’s stock designs. This chassis fits any Ruger® 10/22® or similar receiver, trigger group, and barrel (standard or bull barrel).
I’m probably a bit partial to LUTH-AR, but their adjustable MBA rifle buttstock is the only stock I use on my competition rifles and the only one I’ve found that I can customize to me. As a company, LUTH-AR is innovative, listens to the feedback they receive, and many of the people who work there, including the Founder, Rany Luth, are competitive shooters. They find solutions to competitors’ and shooters’ problems that are commonplace throughout the industry today. The MCA-22 Rimfire Chassis was designed by Mark Roth, Co-Founder of Roth Performance, who is also a long-time competitive shooter and entrepreneur. Roth Concept Innovations, LLC (Roth Performance) is an innovative company that develops new firearm products to solve problems or improve existing firearm products and manufacturers custom shotguns. Between these two companies, I think they are successful in offering one of the best customizable and comfortable rimfire rifle chassis on the market today.

Here are 5 benefits of the MCA-22 Rimfire Chassis:
1. Adjustable and Ambidextrous
The biggest benefit of the MCA-22 Rimfire Chassis is the ability to adjust the length of pull, the cheek piece, and the butt pad to you. Just like one size does not fit all, firearms do not fit everyone either. The industry is full of aftermarket accessories like stick-on cheek pads and extended butt pads, but those items still might not allow you to get that perfect fit for your firearm. This one chassis doesn’t require any aftermarket parts to set up the gun for any shooter. The best part of this chassis is it’s completely ambidextrous for both left and right-handed shooters. Here are the specs of the adjustability:
- Length of pull adjustable from 11.25” to 15.75” in .75” increments
- 1″ vertical butt pad adjustment
- Click-adjustable cheek piece – front and back .750”/up and down 2”(+1”/-1” from bore center)
2. Easy Installation
The installation process could not be easier. Depending on what kind of 10/22 action, trigger group, and barrel you have, you may have to unscrew one or two screws on your old chassis to remove these three parts from the gun. The installation on the MCA-22 Rimfire Chassis requires dropping in the action, trigger group, and barrel and tightening the installation screw on the bottom. There is one difference if you’re using a bull barrel rather than a standard barrel. The chassis has an insert already in it that perfectly fits standard barrels. If you have a target or bull barrel, you will need to remove this insert to make it fit. With the insert removed, it can accommodate barrels up to .920″ diameter.
3. Accepts Aftermarket Accessories
The optic of choice will depend on the action/receiver. Most will have a Picatinny rail to set up a scope, red dot, or iron sights. The chassis itself has two locations to accept Grovtec threaded QD cup inserts. It also has a 5-slot M-LOK® compatible foregrip bottom with 1 M-LOK® slot on both sides of the foregrip. If you like varmint hunting, you can sling this 10/22 rifle easily and not have to carry it by hand.
4. Lightweight & Perfect for Teaching Kids
I taught my then 5-year-old nephew how to shoot .22 action rifles and pistols two years ago. I wish that this chassis had existed back then. Our biggest struggle was he couldn’t get his cheek on the stock and see through the scope at all. The height was all wrong for him. The stock was too long as well and made it difficult for him to reach the trigger. We also used the back of my old truck and a bag for support because he couldn’t lift the gun without getting quickly fatigued. The MCA-22 Rimfire Chassis is only 2.09 lbs, compared to most .22LR rifles that are anywhere from 4 to 5 pounds and beyond. I could teach 100 kids how to shoot with just this one 10/22 chassis simply because I can adjust it for each one.
5. The Ultimate Competition Chassis
Finally, the MCA-22 Rimfire Chassis is perfect for use in Steel Challenge, Rimfire Challenge, NRL22 Competitions, Practical Rimfire Challenge matches, and countless other rimfire matches. While plinking around with just iron sights, I realized how fast I could swing the complete rifle from left to right while practicing Steel Challenge stages. Speed is everything in competitions like Steel and Rimfire Challenge, but you also have to be able to hold the gun up for multiple strings on multiple stages. Even I get fatigued with a loaded out pistol caliber carbine, topped with a primary and offset red dot, so I immediately see the benefit in using a 2 lb chassis rather than something heavier. There are quite a few shooters, too, who shoot both red dots and iron sights on the same gun. They use a QD mount to remove the red dot when it’s time to shoot irons division and then re-mount it to shoot open or optics division. Depending on the red dot and the mount used, you may need to raise or lower the cheek pad to have a good line of sight for your red dot. Adjusting the cheek pad takes seconds with this chassis, and you’re immediately off to the races. Pretty cool!
I have recently started to shoot more Steel Challenge, and I enjoy shooting NRL22 as well. I cannot wait to shoot a match with this chassis and see how I do. I’m also looking forward to teaching my youngest nephew how to shoot as soon as he’s mature enough, and I’ll be sure to use the MCA-22 Rimfire Chassis designed by Roth Performance and produced by LUTH-AR.
What I love most about this chassis, though, is the joy that it brought me. I tend to forget that enjoying shooting guns is what got me into shooting sports. I rarely plink for fun, or I’m always in competition mode rather than shooting for the pure joy of shooting. It was very rewarding to giggle and play with this new chassis, just like I did as a kid.
If you’re like me, you appreciate a good product that solves a problem, but buying American-made products is also important. The MCA-22 Rimfire Chassis is completely made in the USA and the two companies who came together to make this a reality give back to the shooting sports and are proud supporters of the 2nd Amendment. It doesn’t get much better than that! Learn more about this chassis and get yours today on LUTH-AR’s website.
