Should not have probs with any new rifles its all makers not just daystate, and a 300 pound bsa ultra or aa s200 will match any top end rifle for performance when matched to the right pellet as we know its what fits you or pushes your buttons, Im a big fan of the hw100 and always will be cracking rifles but not without probs i have had 3, 2 crept over power and the last one was inconsistent over the chrono and Darryl looked at it, it is running sweet and has done ever since, but since getting my airwolf it hasnt hardly been used, im a daystate fan they are superbly accurate and reliable even
