So I bought a Spike's Tactical BAR rail when I ordered my Stag Arms with the intent to install it when I received my rifle. Long story short the muzzle break is pinned and will require some machining. I would prefer to have the barrel cut down from 16.5" to 14.5", re-crowned and threaded. Is it legal to do this since the rifle is already classified as restricted? Would it require re-registering the length? If it is legal to have this done, by the time I paid a shop for the work, would it be just as cheap to buy a new barrel? The only other option I can see would be to drill out the pin in the break in order to install my new gas block (I am not interested in cutting down the A2 sight). Thanks and sorry for all the questions, I am still pretty new to the world of ARs.
