Jay,
Not sure about a price but I would bet they are cheaper - they won't have HARRIS on them will they. Anything designed and made in Barlow, Kentucky by a bunch of real nice people is worth stickin with.
Jake, if you are talking about maintaining the tension on your swiveling bipods there are two ways that I know of. First is a kit that is available from Brownells that has a small washer-type spacer and a machine-tool handle. You simply remove the knurled knut and put on the spacer and then the handle. Lets you set the tension very easily and holds good.
Second is to simply order one of those little machine-tool handles thru a machine-shop or machine tool supplier, grind an 1/8th of an inch off that central bolt (means you have to take the assembly apart) and then re-assemble and put the tool handle on instead of that nut.
First way is simple, no dis-assembly and grinding, someone has found the necessary parts and packaged them for you. Second is much cheaper and not very difficult if you have a Dremel or grinder, but you have to track down the little handles.
You can "park" the little handles so that they are not in the way (pull the handle outward and re-position it where you like it).
If you would like to see this setup I can send you a jpeg, no idea how in hell to post pictures.
I would not use a swiveling Harris without this modification.
