Black Nitride 1.25" Heavy Duty Push Button Swivel - GTSW314

I am hard on my rack-grade carbines in the field. Scratches + dings happen while running drills/exercises, and before I got Grovtec's heavy duty sling swivel button, I had twice had carbines hit the deck when, for whatever reason, the push button failed. So lesson learned: never put cheap Chinese crap on a hard-use gun.
Since my first Grovtec push button swivel, I've added several more to other rifles and I've got every expectation of being able to rely on these parts for a long, long time.

Nice, deep, dark nitriding is tough and even though one of the push button swivels routinely scrapes along gravel, blacktop, mud & dirt, rain & pond water, snow and every other type of weather over the last 4 years, the nitriding still looks beautiful and definitely is doing its job

Grovtec is local to me, too, I just learned. Glad to know that.
