So ive just order my vz (it hasn't arrived yet) and i had this idea. Ive always liked the look of the 15.4" barrel over the long 18.5". So i got the idea to move the front sight block back down the barrel to the 15.4 position and machine a custom muzzle brake (think ak type 103) to hide the remainder of the barrel. My question to cgn members is: what will this entail and how should i go about doing this? Should/can i machine the front sight block so it fits over the thicker part of the barrel? Or should/can i machine the barrel down so that the sight block will fit? What do you guys think?
