I have owned my Firebolt for 2.5 years and have had no problems.I took it coyote hunting and shot a 70 lbs. female at 217 yrd. She was on a dead sprint when I hit her and she dropped in her tracks.My Firebolt is in the .45 cal. and I use the Precision Rifle .357 Dead Center bullet that weighs 195 grains with 120 grains of Triple 7 FF.This inline shoots 1/2 MOA and I wouldn't trade it for any other in line out there.

Good Luck
