Hi,
I got the Archangel kit for 10-22 and do like it, although my son has a Mossberg 715T and I like the fact that the stock is adjustable on his. It is a bit bulky, but sure changes the rife. My only real complaint is that the rear sight is kind of cheap and hard to adjust. I'm going to pick up a rail mounted AR style rail sight and use that instead. It looks pretty cool with the fake suppressor! Make sure to order extra mags, as they are hard to find. No problems with feeding ammo in the 25 rd clip.
