I took my 522 out again today (it had been a while) and as always I seem to forget how much I love that gun. My only complaint is that the trigger is heavy and gritty. I’ve read up on an old AR15.com link about how to clean it up, but all the pictures are gone thanks to Photo Bucket.

Just wondering if anyone had done the modified AR-15 hammer spring mod and if you had any tips, tricks or otherwise?
