I think a few of the tech force rifles were made by Mendoza, though good luck finding one. I had an RM 200 in .22 for a while. I bought it used from Pyramyd and it dieseled forever before settling down though the barrel fouled with carbon till the day I sold it. It was light and handy, the trigger was decent-the double bladed style. The big issue for me was the scope would not stay put no matter what I tried. It was also built like a tank.
After 5 years I STILL want a Mendoza Quetzalcóatl,
