Were they actual Harris bipods? There are tons of cheap knock offs out there.
I have been using the S-BRM for a number of years now.

I did replace the tilt lock to a lever which is far superior.
The sling mount is not very consistent. I saw recently someone was selling an Arca and picatinny QD mount which looks pretty slick
By the time you buy the bipod, lever, QD mount, and feet(which I haven't done) you're in $200.
