When you're running a belt-fed upper like the FightLite MCR, the feed system relies on a handful of small parts all doing their job in sync. This is the return spring for the feed cam lever arm, and while it isn't the flashy part of the gun, it's the kind of piece that keeps everything cycling the way it should. The lever arm controls the timing of the belt-feed mechanism, and this spring is what returns it to position on every cycle.
It's a factory FightLite Industries component, part number 15084, and it drops into the feed cover assembly on the MCR, Shrike 5.56, and the military AMG-2. That broad fitment is handy since these platforms share a lot of DNA. Whether you're rebuilding a feed cover or just topping off your parts stash, this is the correct spring for the job with no guesswork about compatibility.
Belt-fed guns live and die by their timing. The feed cam lever arm actuates as the bolt carrier cycles, indexing the belt so the next round lines up with the chamber. If the return spring gets tired or takes a set, that timing can drift and you'll feel it in reliability. Keeping a fresh one on hand means you can swap it out at the first sign of trouble instead of babying a worn part through a range day.
Parts like this are cheap insurance. Small springs are exactly the sort of thing that walk off during a detail strip or wear out quietly over a lot of rounds, and having a spare in your kit beats waiting on a shipment when you'd rather be shooting. If you own an MCR, a Shrike, or an AMG-2, this belongs in your maintenance box alongside your extractor and ejector springs. It's the same quality FightLite builds into their complete uppers, just sold on its own so you can keep yours running.
It's the return spring for the feed cam lever arm, which controls the timing of the belt-feed mechanism. As the bolt carrier cycles, the lever arm indexes the belt so the next round lines up with the chamber, and this spring returns the arm to position on each cycle. A healthy spring keeps that timing consistent and your feeding reliable.
Yes. FightLite lists part 15084 as fitting all models of the MCR, the Shrike 5.56, and the military AMG-2. These platforms share the same feed cover architecture, so the spring is interchangeable across them.
It is. This is the genuine FightLite Industries spare, part number 15084, made in the USA. Using the factory spring means you get the correct spring rate and dimensions for proper feed timing rather than a substitute that may not perform the same.
It's a smart move. Small springs like this can take a set or wear out over a high round count, and they're easy to misplace during a detailed cleaning. Keeping one in your parts kit means you can swap it fast instead of waiting on an order, which matters most when you're mid-project or headed to the range.
