Specs of The AR-TT
Overview
The LAT is The Triggered Company's match grade refinement of the Disruptor — a 3-position forced reset trigger built for shooters who want the absolute best pull quality and variable rate-of-fire control in a single cassette. Lighter pull. Three positions. Named after a legend.
If the Disruptor is the standard, the LAT is what happens when The Triggered Company pushed further. Tested beyond 6,000 rounds under a course of fire derived from the USMC M27 IAR evaluation criteria.

What Is ARSE Mode?
ARSE — Assisted Reset Semi Enhanced — is The LAT's third position and the feature that separates it from every other FRT on the market. Unlike the standard forced reset mode where the rate of fire is driven by the cycling of the BCG, ARSE gives you shooter-controlled variable rate of fire.
- Pull it firmly — get a slightly reduced pull weight forced reset at a controlled cadence
- Pull it gently and let it run — the trigger resets at full speed and the rate follows your BCG's cycling rate
No other trigger in The Triggered Company lineup offers this. It is unique to The LAT.

Named for a Legend — Major Larry Alan Thorne
Larry Alan Thorne — Hall of Fame Badass
Born Lauri Alan Törni in Viipuri, Finland, Thorne fought Soviet communism under three flags — Finnish, German, and American. By 1943, Stalin had placed a bounty worth three years of a Soviet General's salary on his head for his raids deep behind Soviet lines during the Winter War and Continuation Wars.
After the war, Törni made his way to the United States, became Larry Thorne, and — through the personal intervention of Wild Bill Donovan, founder of the OSS — joined the United States Army as a Green Beret. He returned to his life's calling fighting communism in Vietnam.
Major Larry Alan Thorne was killed in action in Vietnam in 1965. His remains were unrecovered for decades, identified in 2003, and he now rests at Arlington National Cemetery. His decorations span three nations and include the Mannerheim Cross, the Bronze Star with "V" device, the Legion of Merit, and the Distinguished Flying Cross among dozens of others.
The LAT carries his initials. Every round fired is a tribute.
