7075-T76 Aluminum Alloy

Proudly designed and manufactured in the USA.

Due to demand, we’ve produced an oversized tactical knob made from high strength 7075-T76 aluminum alloy designed to fit all our bolt handles. This ubiquitous design is made from the best T76 temper that we can source and then mil-spec hard coat anodized (type 3) for durability. The threaded section is 1.2″ (30.5mm) deep, so it will shoulder up against every type of handle we’ve come across. The knob has 5/16″ x 24 TPI threads. Weighing in at just over 1oz (33.6g), our alloy knobs are CNC turned to tighter tolerances than what is possible with the molding process of our carbon fiber knobs. We manufacture these in significant volume to keep the price as low as possible. You would be hard pressed finding a stronger, harder and more durable alloy knob at this price.

This bolt knob was designed by Area 419 to be the best all around bolt knob for competition and general use.  Its main feature is the finger groove which allows you to manipulate the bolt with just your pointer finger without searching for the ideal position each time.  Your finger automatically catches in the groove to assure the fastest, smoothest bolt manipulation.  There are two knurled surfaces located on either side of the groove to give a sure grip.

Made in the USA from 6061-T6 aluminum and anodized flat black.

Bergara and CZ 457 bolt knobs are threaded M6x1

This is a high strength replacement bolt knob, CNC turned from stainless steel (304) for the Lithgow CrossOver. Our bolt knob replaces the factory synthetic item. It is 2mm longer and 2mm wider and mimics the style of the classic Winchester 70 bolt knob. No gunsmithing is required to fit the bolt knob, it screws directly onto the CrossOver’s bolt handle (M6 thread). In production, the bolt knobs will be glass bead blasted and then cerakoted to match the original factory finish of all external metalwork.

We recommend installing the knob onto your bolt handle with a low-strength thread locking compound applied to the threads (nothing stronger than purple loctite 222 or equivalent).
