No. GrovTec US, Inc. began business in May, 2006 after acquiring machinery from a company that ceased domestic swivel manufacturing to source their products overseas. GrovTec US, Inc. is an independent, privately owned company dedicated to bringing you high quality, innovative products made right here in our Wood Village, Oregon manufacturing facility.

A recent test of our standard 1" locking swivels pulled tested to withhold tension over 500 pounds and our heavy duty 1-1/4" push button swivel rated even stronger, holding over 584 pounds of tension.

Absolutely not. Our barrel bands are of a proven design that when properly fitted, will provide you years of rugged, dependable service.  Here is a hint for installation that has worked well for others:  When assembling around the barrel or magazine tube, do not tighten the upper screw all the way at first.  Just put it in finger tight.  Leave a slight gap about the thickness of a credit card between the two halves and then tighten the lower hollow screw very snug.  Then tighten the upper hex screw.  By leaving a small gap with the upper screw, that allows it to work as a pivot point to tighten the barrel band by spreading the band with the lower hollow screw.  Then when the hollow screw is snug in place, then go ahead and tighten the upper screw and you’re done.

Drill a 5/32” hole slightly longer than the length of the wood screw stud you are installing (i.e. for a ½” wood screw, drill a 9/16” deep hole.). Then countersink a 7/32” hole 1/8” deep into the original hole.  You will find that our GTHM-286 Sling Swivel Stud Installation Tool will make it much easier to install your swivel studs.

You can use either our GTSW-34 or our GTSW-296 push button magazine cap. These are designed specifically for the 870 Express. You can tell the difference by looking at the inside of the magazine cap. The cap for the 870 Express™ has internal detent slots on the inside of the cap. The magazine cap for the 870 Wingmaster™ has dimples on the lip of mag cap.

The washers are a totally optional component of our swivel sets.  You may like the look of a white spacer like the older Marlin 336 with the "White Line Spacer" and classic Remington 700 BDL's, or you may prefer the the subtle appearance of the black spacers to provide a smooth transition from the swivel stud to the wood stock.  You may also choose not to use them at all and just have a simple wood to metal fit between the stock and the swivel stud.  The washers are included to give you the option of how you want your firearm to look.
