That's how I did with my Tavor SAR. A lefty is impossible to find in MA, so I hopped on Gunbroker and bought one from a gun shop in Florida, had it shipped to 1776 in Walpole, and they pinned and welded the muzzle brake I provided.
1776 is now closed, but Tim now works out of Gartman Arms in Foxboro. Highly recommend.
