Free: Contests & Raffles.
Depending in what type of hunting you do and what you are looking for I really like the quick-stix system. Makes a bipod out of your walking sticks and attaches via the rail. I find it’s super adjustable and very sturdy. Again might not be what you are looking for but if you already use walking sticks it’s a really good option
Have you checked out Spartan?https://javelinbipod.com/collections/bipods/products/javelin-lite
I am kind of a bi-pod whore, keep trying to find the perfect unit but haven't found the winner yet... I have atlas, magpul, gg&g, rugged ridge, Harris (and cheepo copies), and spartan. Each have their qualities, I will say that Harris is still the most simple, most cost effective choice that 90% of people will be happy with. I do want to try a triple pull, but DAMN it hurts the wallet!
