Browning 22LR. 15 rounds, light, very fast and accurate. 30 degree lever throw makes it nearly as fast as a semi-auto. I have a 6x Zeiss on mine with Zeiss QD mounts so the iron sights can be used as back-up or teaching. I've put a rubber stock pad on mine because the original was plastic and slippery. I use a slip on "barrel weight" (have to call it that here).
