The rail is a good thing. I have also put their sling kit on mine. The stock extension is currently out of stock, and I can't find one anywhere for mine. K-T is expecting to make more, but it may be as long as 6 months. I'm waiting for something to come in from Ebay, and can let you know how that goes. You might look into a front grip for the rail, or a laser/light setup. I have a light kit coming also. I even ordered a rail mounted bipod for range use. You're only limited by your imagination, and a little research. Have fun with it.
