well ive shot about 5000 rounds through my lm4 and the bolt catch seemed to get all soft on me. now instead of having a nice hard press on it to release the bolt, it just requires very little force to release the bolt. No i dont have any mods and no its not the bolt face. This happens when i put in a brand new bolt with no wear also, it just releases very softly with very little force. Also when i split the receivers i notice that the bolt catch seems like it isnt very springy anymore. What is wrong with my lm4? im new to gbbrs and dont know much so any help is appreciated! Thanks!

If the BCG face is fine and the bolt stop is fine then it's either the detent spring or plunger that's worn out or the buffer spring could've lost some tension. I doubt the buffer spring would've lost a lot of tension to be the cause so it's probably the detent plunger or spring.
