Great deal, good quality - ADE Advanced Optics Mini Green Laser Sight

Just mounted this is my Kriss Vector 9MM, I then proceeded to bore sight the ADE HG54, it dialed in great for approximately 10 yds. I then went to the range to dial it in to 15 yds which was an easy adjustment. After placing 100 rounds on target the HG54 it remained very close to the original mark. It wasn’t even worthwhile to adjust. I’ll see after the next visit if it needs adjustment again, but from what I got and the price of this optic it’s well worth the purchase. I’ll probably order another here in a bit. Great deal!!
