I’ve looked at the kriss and although tempted, decided that you can’t beat a 15-22 for a .22lr dedicated rifle when it comes to price, customization, magazines and reliability. If I wanted an all metal AR-22 trainer, I’d buy a CMMG conversion bolt and mags or PSA upper for my AR-15.

Thanks for your take.
