Chassis Rifle Genesis — Building a Precision Tactical Rifle Video

masterpiece arms tactical rifle gunsmithing milling CNC CAD

How is a modern, metal-chassis rifle built? This very cool video from Masterpiece Arms answers that question. The nicely-edited video shows the creation of a Masterpiece Arms tactical rifle from start to finish. All aspects of the manufacturing process are illustrated: 3D CAD modeling, CNC milling of the chassis, barrel threading/contouring, chamber-reaming, barrel lapping, laser engraving, and stock coating. If you love to see machines at work, you will enjoy this video…

Triangle Cleaning Patch — Innovation That Works

Rigel BoreSmith Brush Patch Jag Pyramid Triangle patches

Product innovation is all about “building a better mousetrap”, or in this case, building a better bore-cleaning patch. A real smart guy, Shane Smith, has invented a triangular patch that earned a patent. The U.S. Patent Office has awarded a utility patent for BoreSmith’s Triangle Patchâ„¢. This unique cleaning patch was designed by Shane Smith, a mathematician/physicist who employed his scientific and firearms knowledge to create innovative bore-cleaning products.

BoreSmith’s clever Triangle Patchâ„¢ (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). In addition, the Pyramid patch is must less likely to jam due to pleating. One reason conventional patches get stuck is unwanted 5-layer pleating. The special notches in the Pyramid patch remove all or most 5-layer pleating. As a result the patch does not bunch up and this also reduces rod bowing. SEE Triangle Patches HERE.

The Triangle patch can be used with a standard jag but works best when paired with BoreSmith’s patented dual-diameter JagBrush. There are FOUR sizes: 17-20 Caliber, 22-27 Caliber, 27-35 Caliber, and 35-58 Caliber.

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

NOTE: Despite what you may see in this video, you should ALWAYS insert brushes and patches from the chamber end first, using a fitted 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.

The Triangle Patches work great with Boresmith’s patented dual-diameter bore brushes:

Practice Marksmanship at Home with Creedmoor’s Air Gun Range

Creedmoor sports air rifle airgun practice indoor range curtain targets

Air Rifle Range BackstopWith the COVID-19 Pandemic, many shooting ranges remain closed or severely restricted. And in some cities there are still stay-at-home orders in place. If you’re an avid rifleman who enjoys shooting regularly, the Pandemic lock-down can bring withdrawal pains. The closure of outdoor ranges can mean months of forced inactivity, unless you have indoor shooting solution — such as this indoor airgun target backer system from Creedmoor Sports.

If you cannot practice at a nearby public range, Creedmoor Sports offers a great solution for those who want to shoot indoors — even in your own basement or garage.

Creedmoor’s patented 10m Air Gun Range provides a target holder and a curtain-type backstop capable of stopping pellets with a muzzle velocity up to 600 fps. The target boxes can be positioned at various heights for prone, kneeling, and standing. Creedmoor says the hardened steel target boxes provide 100% containment for any pellet passing through the target.

The 10M Air Gun Range is sold as a one-station range for $425.00 (item AGR-SINGLE), a 3-station configuration for $1614.00 (item AGR), or as a 6-point firing point for clubs for $3228.00.) For personal use, the one-station range is what you want — and it’s affordable at $425.00.

Creedmoor’s Air Gun Range is a proven, heavy duty product — the only Air Rifle target system ever tested and approved by the U.S. Military. This system is now being used in more than 800 schools nationwide, as well as the CMP shooting facility in Alabama. The 3-station range easily dis-assembles for transport and storage, fitting inside a 34″ x 10″ x 8″ carry duffle. The one-station range measures 84″ high x 30″ wide when assembled.

The Portable Air Gun Range comes with a durable curtain/ backstop that sets up quickly and easily. Velcro edging allows multiple curtains to be joined together. The curtain provides ample stopping power for air pellets. However, this is NEVER to be used with rimfire or centerfire rounds, or even high-energy pneumatic hunting rifles. This is for standard airguns only. That could be a $100 Crosman, or a $3600.00 Model 9003 S2 Anschutz:
