Forgot about the buffer. The originals get brittle with time.
A 26 in field SuperX 1 isn't exactly light for all day carrying, but not obnoxious either. Wouldn't be excited about carrying one all day at the ready for Ruffed Grouse, but have walked a good bit for Pheasants with one. They are great for pass shooting Doves and have used one for Geese years ago. Have also use one for spring Turkey.
I have one I have shot around 20,000 for clays. Replaced the buffer a couple times and the stock spring just for the heck of it. Have also lost a charging handle. Some are in there tight and some not so tight.
The trigger group does tend to get dirty with heavy use, more so than most modern autoloaders.
