The SINCLAIR INTERNATIONAL AR-15 Magazine Safety Block is designed to ensure safety on the range by rendering AR-15 rifles inoperable.
It features a bright yellow color for visibility and securely locks into the magazine well, requiring bolt retraction to unlock.
While it provides a visible indication of a safe weapon, it does not replace the flag required for NRA/CMP competitions.

The Sinclair Priming Tool is crafted from high-quality materials such as stainless steel and aircraft-grade aluminum, ensuring durability and a lifetime of trouble-free use.
It is designed for precision with features like a tool head that locks the case head square to the priming punch, and it provides excellent leverage while being sensitive enough to feel the primer seating.
The tool includes housings and punches for both large and small primers but requires separate purchase of Sinclair Priming Tool Shellholders, and contains no plastic parts to wear or break.

Sinclair Priming Tool Shell Holders are precision ground from stainless steel for durability and precise fit.
Designed specifically for use with the Sinclair Priming Tool, ensuring compatibility and optimal performance.
Accommodates a variety of cartridges including 308 Winchester, 243 Winchester, and 270 Winchester among others.

The Sinclair forend adapter provides a stable surface for shooting, compatible with Freeland-style and Anschutz accessory rails.
Features an extra-wide, anodized aluminum base with twin runners for smooth rifle recoil management.
Includes a Sinclair Picatinny Rail Adapter for use with rifles that have a Picatinny rail on the forearm.

The SINCLAIR FIRING PIN REMOVAL TOOL is designed for easy disassembly of the firing pin, spring, and shroud assembly from various Remington and Kelbly Stolle bolt actions.
It is not compatible with 40X rimfire actions, but works with a range of other models including the 40X, 600, 660, Model 7, XP-100, 700, 721, XR-100, and 722.
The tool features a non-marring Delrin body and is essential for routine cleaning, oiling, and inspection to ensure the proper function of the firearm.

Sinclair Carbide Neck Expander Mandrels are made from solid carbide for precision and lubricity, reducing galling and material transfer.
The mandrels are designed .001" smaller than bullet diameter for optimal neck tension and concentricity when used before neck turning or bullet seating.
Compatible with the Sinclair Expander Die and Neck Turning Tools, these mandrels are specifically made for 30 Caliber with a diameter of 0.307 inches.

The Sinclair Stainless Ultimate Trimmer is a highly accurate stainless steel version of the Wilson Case Trimmer, exclusive to Sinclair International.
It features a unique case holder system that holds cases by the body taper, ensuring consistent trim lengths by aligning cases square to the cutter.
The trimmer integrates a Sinclair Micrometer head for precise adjustment, with no need for pilots or collets.

The Sinclair Bullet Seating Depth Tool is made from stainless steel and is designed for both small caliber (17 and 20) and larger caliber (22 and up) rifles.
It enables precise measurement of loaded round length touching the rifling using fireformed brass and bullets, and is compatible with most bolt action, single shot, and AR type rifles.
The tool comes with a Delrin action guide for bolt-action rifles and has additional guides available for AR-15's, AR-10's, and Tubb's 2000's, ensuring accurate Base-To-Ogive measurements when used with Bullet Comparators and calipers.

The SINCLAIR INTERNATIONAL O-Ring Rod Guide is designed to seal the barrel from the receiver, preventing solvent leakage into the action area.
It is compatible with a range of cartridges and actions, including .243 Winchester and McMillan Tactical, with a .720" bolt diameter.
Upgraded versions now include integral solvent ports, with custom options without ports available upon request at no extra charge.

The Sinclair/L.E. Wilson Micro-Adjust Bullet Seater allows for precise seating depth adjustments with .0005” increment clicks and a graduated scale for consistency.
Each seater stem is custom fitted to its body for close tolerance, and the die is constructed of 416 Stainless Steel for durability.
The bullet seating die is made in the USA by L.E. Wilson, leveraging 85 years of experience, and is available for 12 popular cartridge types including the 308 Winchester.

The mandrels are precision-made from high-grade stainless steel and are designed to fit both NT-3000 and NT-1000 neck turning tools, as well as most older models.
Expander mandrels are sized 0.001" larger than turning mandrels to provide a perfect fit for the neck turning process, making it more precise and easier.
These mandrels can also be used to increase case neck size up to the next caliber with the NT-EXP Expander Body.
