BoreSmith Patents Triangular Patches and Dual-Diameter Brushes

The U.S. Patent Office has awarded BoreSmith utility patents for two unique gun cleaning products. Patents were issued for BoreSmith’s triangular Pyramid Patch™ as well as BoreSmith’s dual-diameter JagBrush™. Both products were designed by Shane Smith, a mathematician/physicist who used his scientific and firearms knowledge to create innovative bore-cleaning products that may well work better than conventional patches and brushes.

BoreSmith’s clever Triangle Patch™ (aka Pyramid Patch) presents more cleaning surface area to the bore wall than does a conventional square or round patch (of equivalent size). At the same time, the unique geometry makes Triangle Patches much less likely to jam in the barrel. This is because the notches in the sides of the triangle allow the patch to sit more uniformly on the jag (without bunching up). The Triangle patch can be used with a standard jag but works best when paired with BoreSmith’s patented dual-diameter JagBrush. Order Triangle Patches HERE.

Triangle Patch Function and Geometry Explained (See 1:18 time-mark):

NOTE: Despite what you may see in this video, you should insert brushes and patches from the chamber end first, using a well-fitting cleaning rod bore guide. With bolt-action rifles, NEVER insert a cleaning rod (with brush or jag) in through the muzzle. This may damage the delicate crown of your barrel.

Patent Awarded to Dual-Diameter JagBrush
The JagBrush is like a standard bore brush but has two different diameters on the bristle section. Bristles in the front are smaller, while the rear bristles are similar length to a standard bore brush. When a patch is pushed through the bore using a JagBrush, the smaller bristles will grab the patch, leaving the longer bristles exposed and creating a dual-­action wiping + brushing system. JagBrushes are offered in a wide variety of calibers, in both bronze and nylon versions.

6.5 Grendel is Approved as SAMMI Cartridge — Alexander Arms Gives Up “6.5 Grendel” Trademark

At the gun industry writers round-table meeting earlier this month in Kansas City, KS, Alexander Arms made important announcements regarding the 6.5 Grendel Cartridge.

1. The “6.5 Grendel” has been officially approved as a SAAMI Cartridge. (This means that cartridge dimensions will be standardized for the purpose of manufacturing brass, loaded ammunition, pre-fit barrels, and 6.5 Grendel-chambered firearms.)

2. Alexander Arms has officially “relinquished” its trademark claim on the term/label “6.5 Grendel”. This opens the door to other companies offering products (such as ammo, barrels, magazines) which are identified by the 6.5 Grendel moniker.

Here is the text of Alexander Arms’ Official Press Release:

The 6.5 Grendel is an Official SAAMI Cartridge and Trademark is Relinquished.

The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) has adopted the 6.5 Grendel as an official SAAMI cartridge. As a result of the cartridge’s official recognition, Alexander Arms will relinquish the trademark “6.5 Grendel”. Bill Alexander states: “One of the primary purposes of trademarking the name was to protect the integrity of the design. With the adoption of the 6.5 Grendel cartridge standard by SAAMI, the design is now protected, and any confusion in the marketplace as to the specification of the cartridge has been eliminated.”

SAAMI’s formal adoption of the design specifications for the cartridge has led Alexander Arms to announce that it will relinquish its federally-registered trademark and that “6.5 Grendel” to be the common commercial name for a cartridge that adheres to the specifications adopted by SAAMI.

Alexander Arms is proud that a cartridge of its design has received this important designation, and is pleased to take this important step in the continued market development of this breakthrough cartridge, which is perfectly matched to the AR-15 platform.

According to The Firearm Blog, “Hornady submitted the cartridge to SAAMI last year but the application was rejected because Alexander Arms refused to relinquish the trademark.” With the waiver of trademark objections by Alexander Arms, look for greater production of standardized 6.5 Grendel ammo and brass. We can also expect more factory and custom rifles to be chambered in the efficient 6.5 Grendel cartridge. Some gunsmiths had avoided working with this cartridge because of Alexander Arms’ trademark claims. In fact, the were even concerns about sales of “6.5 Grendel” chambering reamers, so some gun-builders developed slightly-different wildcats in order to get around Alexander Arms’ objections. But that is all “old history” now….
