Follow-Up
Just a follow-up to my original post, subsequent to my first two-gun Steel Challenge match. (I had previously shot one steel match with a pistol only.)
I did purchase two rear sights, including the recommended UTG sight (nice), and one front sight, but ended up not using any of these. (I'll save them for possible later use for Silhouette shooting.) Instead, I made a bushing/collar from acetyl plastic that fit onto the thick "muzzle-weighted" end of the barrel and secured it with small (#6-32) SS set screws. I made the sight post from an allen head screw, and painted it fluorescent orange. (I had previously painted the front post of my BuckMark Target this way.) For a rear sight I used, well, not much. I drew a stripe down the center of the Picatinny rail with a magic marker. The combined result is much like a shotgun sight, allowing fast acquisition and a very open viewing/sight picture, with more than enough accuracy for hitting the steel plates of a Steel Challenge match. I did a quick 25yard test off the back porch using a front rest, and packed the rifle for the range.
I ended up with a mid-pack score (5th of 11), not very fast (yet?) but fairly accurate, with no procedural errors. Of note is that I do not think any of the misses were with the rifle, just a couple with the pistol. The guns of the other ten shooters included a few iron sighted, but most were fitted with red-dot/electronic optics.
At least for now I'm going to stick with this set-up, as it seems to work perfectly well for Steel Challenge shooting. But then, I'm not really concerned with winning, just enjoy the shooting. I'm currently using this same rifle and pistol, with 4-16X Bushnell 4200 and 3-9X Burris scopes mounted respectively, for Silhouette shooting. I'll continue to have a blast shooting rimfire this winter (NRL22/PRS, Steel Challenge and Silhouette) spending as little $$$ as I can using guns and scopes/sights that I already have, or I can work-up inexpensively.
