A Border Patrol statement issued Monday says agents working a remote area about 55 miles up the river from McAllen found the cache of weapons and paramilitary-style gear.
Among the items found Friday were four assault-style rifles, two hand grenades, body armor, two-way radios, military-style uniforms and 16 fully loaded 30-round ammunition clips.
No arrests were reported relating to the find.
