Also, a great way to attract unwanted attention from the BATF.
Anything that is a large caliber "full automatic" is certainly going to be examined by the Feds. Offering a .25 caliber pcp, full auto airgun WILL come back to haunt us.
My advice...don't buy the full auto. Fun to shoot once or twice, but after that...what do you do with it? We don't have "human wave" attacks by raccoons, rats, or unwanted birds.
Let's us some common sense, or we will pay the price when we have airguns that are equal, in close range, to the killing power of full auto powder burners!!!! Remember "Bumpfire"???
You say ".25 caliber won't attract attention" Let's remember the Japanese army fought an entire war with .25 caliber rifles, carbines, and machine guns!!!
Further, we DO NOT have Second Amendment protection!!! That leaves any government law enforcement agency free to demand limits/restrictions/laws prohibiting power, shot count capability, and caliber. Look at Illinois...it's already illegal to own an airgun with a caliber larger than.17, and velocity higher than 700 fps. Wake up!!! It's not only possible, it's already had the precedent set....
Below is the link to what we may expect nation-wide if the airgun industry continues to approach form and function of powder burning firearms:
