This is a set of genuine GrovTec sling swivel studs, machined from blue steel with a common 10-32 machine thread that fits a huge range of rifles and shotguns using this standard threading. GrovTec has built a solid reputation among gunsmiths and DIY gun owners alike for quality hardware that just works, and these studs are a straightforward, no-nonsense way to add or replace the mounting points a sling swivel or bipod actually attaches to. Each stud measures a 1/2 inch overall length with a 1/4 inch threaded section, sized to seat properly into standard stock and forend mounting holes without protruding awkwardly or sitting too shallow. Steel construction with genuine machine threads means these studs hold up to real use rather than stripping out or loosening over time the way cheaper stamped hardware sometimes does. These studs aren't limited to just sling swivels either; they're also compatible with Harris-style bipods, which use the same 10-32 stud mounting standard, making this a versatile bit of hardware whether you're setting up a simple two-point sling or mounting a bipod for more stable prone or bench shooting. If you're replacing a stripped, damaged, or missing stud on a stock or forend, or building out a new sling and bipod setup from scratch, these GrovTec studs are the correct, reliable part for the job.
