I did measure my LOP, after reading up on the subject. Luckily, I got ahold of CDNN, first thing on Monday, and switched my order to a grade 1 bl-22, instead of the micro midas, it showed up at my LGS today, it's a sweetheart, and fits me pretty well, I had a grade 2, bl-22 about 35 yrs ago..got hard up for cash, and sold it, I've regretted it ever since.. Took me awhile but I finally got another one..And unlike the Browning BAR-22 I have, parts are easily found for bl-22's.
