The Harris is made on the exact same machines as they did from the beginning the actual inventor and creator is dead, his family runs it and has turned down every offer to upgrade. That is clue number one
We switch bipod on guys in class all the time to prove this point,
take the lowest common denominator in the class, someone who is demonstrating solid fundamentals and switch the bipod. Every single time without fail, guys will see an instant improvement, often as much as a 50% improvement. Groups that hover around 1.5" will easily become 3/4" with a simple bipod swap.
While many accomplished shooters will claim the Harris is fine, that reality is, they simply adapted to it over time and often have so much rifle over it, it's pretty hard not to have great groups. When you invest a ton in a system and throw a cheap bipod on it, it's the same as training hard for a marathon and wearing Danners to run a race. Sure you can put crappy sneakers on a great runner and he will beat a bad runner, but why work so hard?
We see 100s of students every year and 75% show up with Harris, but once they see what we show them, the class dynamics changes:
There is a reason you see entire lines of high end bipods in our classes, because it makes a difference
Every class here in AK has 16 Students, every class, and without fail, we only see about 2 Harris per, and the next time that student comes back, he has dumped the Harris
We switch stuff all the time, you cannot debate the results,
Look at this bipod, nothing about it says precision, it's completely out of square
