I'm sure that you can mount anything on anything. I have several different size swivel stud (2 piece) units in my parts box that either clamp on the barrel (.44 Mag Ruger DEER Slayer size) or the magazine tube of a .22 repeater size. The larger would prolly fit your strut for a CLEAN looking solution. Most here will likely say that bipod mounting to the barrel (or strut) or even using the Harris Gas Block adapter will negatively affect accuracy. Mount a SOLIDLY anchored swivel stud in the stock forearm and consider floating the Gas Block as described on this forum, I did (along with EVERY other trick found herein) and my #187 series SS Ranch is a consistent 1.250 MOA performer. YMMV !! Joe
