The front sight is a RIA replacement. I won't be shooting critters around here over 150 yards so I'm not going to fuss with it. I have also heard the Aguila is a weak load. I'll run one through the chronograph and report. I scored a 8 pound keg of Lil' Gun and 1000 rounds of very clean pulled GI 110 gr bullets and will be reloading some real soon. Regards, Rick.
