The versatile two-in-one tool efficiently removes carbon fouling from essential areas of the bolt and carrier, ensuring optimal bolt performance and reliable cycling. Utilize the reamer end of the tool to scrape carbon from the carrier and use the opposite end to clean the bolt tail. Its distinctive, lathe-like design adapts to fit any bolt tail radius, providing a universal fit for any AR bolt. Constructed from hardened carbon steel and zinc-plated for corrosion resistance, this tool is an excellent addition to a range bag, field armorer's kit or essentials bag.

The CRT-AR's adjustable arm is engineered to operate akin to a compact, hand-held lathe, providing precision and versatility in machining applications
This design facilitates the cleaning of any bolt tail radius, surpassing industry-standard form tools that fail to accommodate the diverse tolerance variations of different bolt tail radii
The bolt is mounted on the slender pin, enabling rotational movement
As the arm descends onto the bolt tail, its scraper edge efficiently removes carbon deposits during rotation
