Review on Kolpin Rhino Grip XL - Polaris ATV Lock & Ride - 21511: Ultra-Sturdy, Secure Grip for Your Off-Roading Adventures by Justin Frazier

I bought these to fit my 2015 Polaris Sportsman 570. I own it and have been using it regularly for the past 6 months. This is not a durable product. They break with normal use. They don't scratch the rifle, but they don't withstand the normal stresses and strains of the rifle with the weight of the rifle. The bases of each block that hold each mount are cheap plastic and both will break off rendering the entire product unusable. I didn't ride off-road, just rode the trails with a rack-mounted rifle. This is not the best option, a waste of money if you think such a product should last more than 6 months.
