Around 2013 I started shooting Rimfire Rifle Optics division in Steel Challenge matches. Paul let me shoot his ARX-160, which is a fascinating “.22 trainer” version of the Italian 5.56 assault rifle. While an interesting gun with some nice features (Very light, uses standard Umarex mags like the M&P 15-22, and can mount any Weaver/Picatinny optic) it has a rough, heavy trigger. In 2017 I decided to try and build a Ruger 10/22 specifically for use in Steel Challenge. The result is a pretty impressive rifle for a reasonable price.
