Forgive the newbness, my prior bipods were Harris. With the new Atlas, when I load the rifle forward on a smooth surface, the rubber feet rotate, allowing the bipod to travel forward. I was hoping that after the legs are extended to the proper length, the legs could be turned to the right, thus locking the legs/rubber feet. I know there are spiked feet for sale which would I think could address the problem. I did my homework on the website but the answer still eludes me.
