I've got one and I love it. You can dump 30 rounds down the pipe in less than five seconds. (If you drink a LOT of coffee, maybe even faster!)
The original Carbon 15 Pistols, both Type 21 and Type 97, had a feed ramp problem which prevented them from feeding hollow and soft points. Basically, the rounds would slam into the carbon fiber just below the dual feed ramps and jam.
Bushmaster promptly fixed it under warranty. All they did was to mill "feed ramps" into the carbon fiber, effectively extending the steel feed ramps down into the fiber.
This fix solved two problems: The first is that it will now eat about any ammunition type. The second is that it will ALSO use a 20 or 30 round magazine without jammimg. (The jamming issue using the higher capacity magazines was directly related to the feed ramp issue, also.)
Bushmaster tells me that they are fairly certain there are no distributors with the older Carbon 15 pistols in stock. So, anything you buy should have the feed ramp design flaw fixed.
By the way, I do not like the newest version; the one with the barrel shroud. It will doubtless let you hang on to the barrel while firing, thus getting around the need for the foregrip, which would put it in the "AOW" (Any Other Weapon) BATF category and is thus a no-no for Bushmaster, but it looks hokey to me.
Here is a picture of mine. I call her
Little Missy. She ain't the prettiest girl in town,
but man can she rock and roll!
For some reason you may want to shoot it at 100 yards. Just stick a good dot on it! That 7.25" barrel and 5.56mm or .223 round is great for 100 yard shooting . . . from a rest, of course!
And, you will need SERIOUS ear protection.
Little Missy is louder than my fifty caliber Desert Eagle.
