I bought this at the local shop for 430 yesterday, the barrel simply says Model 10. From what I have read it looks more like a 10T, It does not have the detachable magazine but does have the 24" heavy barrel, it is threaded and the previous owner added a pretty beefy muzzle break. I just want to know what I actually have. Planning on changing the stock and adding a detachable magazine if possible. Tried attaching a photo, but i'm not that smart with that yet. Thanks for your help.
