I have a Harris bi pod, the 14 to 30 inch model, or something close to that length. Worked great for a couple of pronghorn hunts. I liked being able to sit rather then lay down in the Wyoming cactus prairie. I also have three short bi pods, the Winchester tagged ones from Wal-Mart. Chinese junk as many here would call them. Held side by side with the Harris, I can’t tell them apart, other then the word Harris stamped on the one. Actually, the deck and hinge tabs on the Chinese made bi pods are a few thousandths thicker then the Harris. I measured them with a caliper. One is on a Remington 700 chambered in 7mmSTW. It takes a beating on that rifle shooting off a bench, and hasn’t failed me yet. Another is on a Saiga .223. Two thousand rounds, and it’s still doing what it’s supposed to. The third is on a NEF Handi Rifle in .223. No problems at all.
