Its really nice because its durable and reliable, and pretty accurate for a 6 inch stub barrel.
The pump stroke is a little bit hard, but not too bad - prevents double feeding.
the 12 gram piercer is a bit slow, but they're correcting that in the 2000 model.
I only have one.
Its great stock, though I'm using it with a remote setup because I hate buying the 12 grams, they're expensive. it is truly in its own class, and it never breaks, so its a great backup. Highly recommended.
