I have both Lyman GPH & Deerstalkers. They are from the early 2000 era and I have found the quality to be satisfactory for their price point and intended purpose. Very reliable and accurate enough to fill the freezer. Some stocks are nicer than others. The locks have functioned flawlessly although they don't have the strongest springs. The triggers are certainly not the best but you can tame them a bit and they do work. If the current Investarms quality is aas good as mine, I would buy another one.......uh. except that I don't need any more.
