I just traded in the Mini-14 on an AR. That was my last real lemon.
I owned a Jennings Bryco years ago in .380. Every time you fired a round the slide barrel assembly where the rear of the chamber was would move back a fraction. By the time I sold it was a good 3/8" off (and yet still shot, albeit wildly).
Tomorrow is the most important thing in life. Comes into us at midnight very clean. It's perfect when it arrives and it puts itself in our hands. It hopes we've learned something from yesterday.
