The metal that locks the legs in place is weak - FAB Defense SPIKE Tactical Bipod

Nice looking bipod and the design is pretty good. Unfortunately the metal that they used is weak as adjusting the legs forward and back a couple times has worn down the grooves that lock the legs in place. On one side particularly, the groove was machined too shallow and the leg slips out of the locking groove without much force on the leg (applying pressure forward or backward) making the bipod useless.
