For most of us that have shot a lot of precision rifle and have seen what works and what doesn't work, the Atlas bipod is about the least expensive top quality bipod that you can get. I have the V8 and the CAL bipods and I would suggest trying the CAL bipod which I prefer to the V8. Get the BT65-NC bipod with no clamp and then get the Really Right Stuff BTC-Pro clamp which will clamp directly to your ACC chassis rails.
My goto bipods for matches are my Atlas CAL and my MDT Ckye pod. For PRS type match shooting, the Ckye pod is, in my opinion, the best bipod out there but they are $500 vs. $280 for an Atlas CAL. For the way I shoot, the CAL is almost as good for shooting matches as the Ckye pod.
And before someone else tells you to go with a Harris bipod, I will say that if you are on a tight budget, a Harris will work but it won't work as well as an Atlas or Ckye pod. I own Harris bipods and I can honestly say they do not allow a shooter with solid fundamentals to shoot as well as they could if they were using a better bipod. Shooting with a Harris I notice the rifle bounces off target much more making spotting impacts harder.
For tripods, RRS is the gold standard but they are very expensive, like $1,500 expensive. Many shooters go with the Leofoto 364C or Feisol 3372 or 3472 tripods which cost 1/2 the cost of an RRS. In this quality level, most people run either a Really Right Stuff BH55 ballhead, RRS leveling base (these are probably the most popular), or RRS Anvil 30 ballhead. I started out with the Feisol 3472 but now have a RRS TFCT-34 with Anvil 30 ballhead. The Feisol needed parts replaced because the anti rotation collar in two of the legs wore to the point of legs rotating and requiring complete disassembly to get working right. I think the Feisol and Leofoto are good values but they are NOT as durable or as good as an RRS.
For less money, I've seen people shoot very well with the Hogsaddle PIG0311 aluminum tripods with a Feisol or Sunwayfoto ballhead. If you're on a budget, they are a good option from a good company.
A good quality tripod with stiff legs is a huge aid to shooting. At a Camp Pendleton match one of the instructors who shoots with us had his Marines compare our RRS tripods and heads to the aluminum Manfrotto's that they were issued and the difference in rifle stability was like night and day. The Manfrottos had skinny aluminum legs that were flexing just from the weight of the rifle whereas our RRS tripods with their rifles on them were rock solid.
