Rare Breed edges Partisan here on raw round count — 10,000 rounds versus Partisan's 6,000+ — but context matters. Partisan's 6,000-round test used a course of fire derived from the USMC M27 IAR evaluation criteria, one of the most demanding sustained-fire protocols in the military. That's a more rigorous test environment than a standard round-count torture test. Both triggers are built to last. Neither has a durability problem in the real world.
Who Should Buy Each Trigger
Buy the Partisan Disruptor if:
- You want the best price-to-performance ratio in the FRT market — $299 versus $499+ is hard to argue with
- You're running a standard mil-spec AR-15 DI or piston build
- You want a lighter, more consistent trigger pull across all selector modes
- You want the cleanest, fastest drop-in install available
- You want to buy from an authorized dealer who bundles the correct supporting hardware with the trigger
- You want to support a small USA company that fought a $588M lawsuit and kept shipping
The only reason to consider Rare Breed:
- You specifically want the ambidextrous selector the FRT-15L3 includes
- You already own a Rare Breed and want a spare — consistency across builds
- Budget is not a consideration and you want the original market name
The Lawsuit — And Why It Makes Us More Confident in Partisan
Rare Breed filed suit against Partisan in early 2026 claiming the Disruptor infringed four of their patents. They claimed $588 million in lost profits. They asked for an emergency injunction to immediately halt Partisan sales.
The court denied it. On February 13, 2026 the judge ruled against Rare Breed's emergency relief on every major factor — likelihood of success, irreparable harm, balance of equities, and public interest all went Partisan's way.
More significantly — evidence at that hearing suggested Rare Breed's own FRT-15L3 may infringe Partisan's older '067 patent. The company that filed the lawsuit may be the one infringing. Partisan then filed a counter-suit on March 24, 2026 challenging Rare Breed's patents directly and alleging misconduct.
