Just made a few of alterations to my sticks. First one was to take off the foam rubber rifle rests at the top which were far too bulky and replace with cycle handle bar grip,much better as slimmer and grips the stock alot better. Second was to drill them on each side and run a sting from side to side to stop them doing the splits when in use. And the final one was told to me last week. If using a bi-pod attatch a long length of string where the bolt holds then together, the scissor bit. That way when in use either stand on the string and push the sticks away until its taught or clip it to your belt loop at the front and push away until taught. It really makes a difference and act like a third leg on a bi pod.
