The Brownells AR-15 front sling swivel staking tool is engineered from precision-machined 1018 steel to facilitate the staking of an original M16-style front sling swivel rivet, eliminating the need for a hammer and punch. Its wide throat design accommodates the swivel easily, while the dual, screw-adjustable 4140 steel stakes, equipped with large, ergonomic handles, allow for precise pressure application. This ensures a quick and accurate expansion of the rivet, resulting in a clean, factory-quality finish without slips or damage. The tool is accompanied by detailed instructions for use.
