The [223-22LR] adapter has just come, and I am extremely happy with it. I can finally hunt in my neighborhood with surpressor and subsonics. Rimfire rifles are not available for Polish hunters. Your adapter gave me the opportunity to shoot with my 223 single shot Rossi Varmint: cheap and silent. I will recommend it to everyone! Groupings are also not bad at 45 feet. I hunted a fox today and shot it with 22lr adapter and it was damn quiet! I love it!
