Straight out of the packet the cleats did not fit my Atlas PSR bipod however, time spent in dressing the cleats with carbide sandpaper solved the problem hence 4 stars. The cleats are very well made and very sharp they should last a long time - a suggestion - it would be helpful if the cleats had a protective sheath included included - when unused but on the bipod, the cleats can easily rip up a rifle bag or foam case

I bought the spikes for an Atlas bipod and they’re a great addition, allow you to weight the bipod far more than with the rubber feet alone. Very helpful company too, thank you.
