I finally drag myself to the range. Took the Glock 19, S&W M&P 15-22 and the Bushmaster. Cool, slight wind and small amount of shooters! The M&P 15-22 was first up to play. Did shoot about 100 rounds, the Nikon Prostaff Scope was an issue of sighting in at short range , I drove me nuts - I adjusted up and down and left and right, nothing! Then the 15-22extractor comes out (all three pieces) . Damn, Remington Target 22LR ammo had a play in it (mabybe). Just to be on the safe side the rifle is heading back to S&W for a warranty makeover and upgrade! I did re-install the extactor after cleaning! Smith & Wesson Forum has 4 pages on this issue. The Bushmaster had a new scope Leapers 5th Gen 6X32 Scope, after some 10 rounds short and 10 rounds long, sighted in with no issues! Glock 19 was enjoying the play time. It did not like the American Eagle ammo that I took to the range. Saturday, take that Nikon and mount onto my other rifle for test and evaluation. I does not work, I am calling Nikon for RMA!
