Possibly, the trigger sears are worn. So you may need a new trigger set, of you can't find replacement parts.

Or it could just be that you need to adjust the buffer tube.

If the hammer is popping up in front of the bolt then the bolt is traveling way too far back.

Start by screwing the buffer tube into the lower until it touches the buffer retainer, if that doesn't work then you will need to inspect and replace the buffer itself if needed,
If the buffer is fine and you screw the tube in as far as it will go and the bolt still rides over hammer then you will need spacers in the buffer tube until the problem is solved, coins usually do the trick.

But all of this shouldn't just happen, have you modified it or substantially dismantled it in any way?
