POTD: Chicharrones' .22 Magnum All Purpose Carbine (with Unique Trapdoor)

Fred Johnson (aka chicharrones on Rimfire Central) sent us photo of his “.22 Magnum All Purpose Carbine” be build by modifying a Zastava bolt action rifle. I live the concept and the execution. Fred writes …

Here’s a creation I came up with in early 2015. I modified a Zastava bolt action rimfire rifle chambered in .22 WMR. At the time, I had a specific desire to have a “survival/truck” carbine that was short, yet still shootable by an adult.

The original rifle was 41″ long and had a 22″ barrel. I cut and crowned the barrel back to 16.25″ and I shortened the length of pull to 13.5″ by trimming the buttstock. The rifle is now 34.25″ long.

I also made a “trapdoor” buttplate, inspired by the Savage 24C. Each hole holds 6 rounds of .22 WMR ammo, for a total 18 rounds in the buttstock.

I installed a new Marbles front ramp/sight and a Williams receiver mounted aperture. On the pre-existing rear sight base, I mounted a modified piece of Weaver rail to mount the Bushnell TRS-25.

The doubled up and modified ammo butt cuff holds two to three spare 5-round magazines. With three full magazines and the buttstock full of ammo, the carbine has 33 rounds of ammo ready to go.

It shoots as well as it did before the modifications with the only limitation being the use of an unmagnified red dot. However, the red dot works very well with a 6 o’clock hold on target and of course it is much more visible in low light compared to the aperture sight.

It was a fun project.

Thanks for sharing!

    He stopped making the 22LR version when the 17HMR and 17M2 became popular due to a lack of interest.

    If you own a rimfire or are thinking of it you really owe it to yourself to check out RFC. I am a Mod there and have been a member since 2002 and we have a huge number of very friendly and very intelligent folks there. Much of what is discussed in not limited to rimfire as we have stock and metal working sub forums. Knife sub forums and many others including everything from airguns to centerfire but the vast predominance is rimfire.

    It started as a 10/22 forum but that was a long time ago. Having said that there is no better place to learn anything about that popular rifle/pistol.

    Jump in the water is fine!!

    Nice, I'd like a smaller profiled and threaded barrel to reduce weight, and give me the option of mounting my Sparrow.

      @uisconfruzed Those rimfire Zastavas have sporter profile barrels. Fat at the receiver like a centerfire gun with a bottle taper just forward of the chamber, then a smooth taper all the way to the end. Before the barrel chop, the muzzle was 0.55" in diameter. After the barrel chop, the muzzle is 0.62" due to the taper.

      Still, the Zastava is all steel and wood not counting the buttplate and it sure isn't a flyweight even after the modification. I figure with the red dot, 3 magazines, and ammo, it weighs what the original rifle did empty and unscoped.

      Here's a review of what the project gun looked like from the factory. http://www.realguns.com/art...
