I do not own one myself, but the Sled Feet competition bipods are the Bee's Knees for F Class.
BEER BUDGET
Get a plastic cutting board to set on the ground. Now get a couple spray paint plastic caps and put them under your bipod feet. This should make a noticeable improvement as your bipod will now slide back instead of jumping.
Red, White or Blue pairs for competition, Krylon Camo Caps for Tactical Rifles.
I have not checked the Rules lately, (Old and Have CRS) so you might want to take a look and make sure the paint caps are not an issue. I have done this at one match and no one said a word about it.
