Yes, most are assembled by Burris. Just look at the Pentax package. Any that are listed as made in USA are burris assembled.
I have a lightseeker 30 and optics are not bad. The nikon and Elites are better but the Pentax has more elevation. Goofy turrents though with 8.5 min per revolution.
Wonder who got the rocket scientist award for that one.
