I just picked up a 18" 6.5 Grendel Sabre Defense barrel. It has their Gill Brake on it and I want to replace it. Is the thread size different on the 6.5 Grendel. What is the size? It is the Mid-weight/ Fluted/ 18" length/ w/ front sight/ pre-ban/ w/bolt assy.
Also does anyone know the inside barrel diameter for the gas block (it has a mid-length gas system) cuz I want to swap the front sight/gas block for a low profile so I could put my 13.2" Larue rail on it. I emailed Sabre D. but no response yet figurded I might get a quicker response on here. Thanks
