I've tried many and many have problems.
Some are just not very stable.... Like the one from Mystic. It's ok for a beginner but you will outgrow it. The wiggle will begin to drive you nutz.
Star Shooter kept rotating due to barrel torque mid string and that caused some grief as I didn't notice at first. I modified it by adding a couple screws on either side of the top plate with thumb nuts to prevent rotation.... That did fix the problem. Unfortunately Star Shooter dismissed the recommendation despite my rant on the point.
Keep in mind that most any bipod will work fine for one shot, like for tactical or hunting applications.
The problem with F-Class is that you need a bipod that will remain stable for 12-17 shots.... without canting... and that either does not move under recoil, or will easily return to the original position.
In the end, out of frustration I just made my own (several times over the years).... but there are some decent options out there... expect to pay plenty for a good one.
Well, I will have to disagree on the stability issues (not sure how you have set it up) and of course, how far you can go with the MPOD.
I do know that the MPOD has helped someone win a World Championship in FTR... has been used to set NRA records in both individual and team. Won matches at the provincial and state level. Been used by shooters that went on to Team USA.
Helped me win a bunch of stuff and even onto the Cdn National FTR Team a couple of times.
I think it is still the lightest FTR bipod on the market and it has even gotten under some F Open and ELR cannons. The new cant adjustment doesn't move during a long 20rds relay and reset is easy if the shooter has set up the rifle and follow through properly.
The design favors what I call "rear steer".... ideally, the bottom of the buttstock will have a taper so fine elevation adjustments can happen with the rear bag - sliding fore and aft. Otherwise, once set up, I don't need to fiddle with it.
Other excellent bipods includes Henry Remples design which is the grand daddy for most of the bipods used today. Built like a tank and about as heavy.. it works and has sat under a number of top Cdn FTR shooters. If you have 4lbs to make weight, it is a solid piece of kit.
The Phoenix is a light variant of the Remple... has its quirks, very popular in the US and I have seen a few in Canada. There are a variety of Remple variants
The Joypod by Seb is another very popular design. Again, has its handling quirks. Very nicely made and presented..... some love the joy stick adjustment... others have moved away from it.
The Star Shooter has a solid presence out East and the manfs are very nice people with a strong love for the Sport.
There is another design from Italy that is a marriage of Road Race bike and a Sinclair bipod. Also very light, adjustments with very small hardware.... looked fragile to me but have not used one personally.
there are a few home grown scissor jack type bipods as well.
Thats kind of the list off the top of my head..
