Ok, i just bought a ats tuner for my vudoo and it looks goofy as hell with just the thread protector, so i have a brake on the way,and no its not for recoil its for total looks only,but im curious if it will affect p.o.i with the tuner? Im thinking so,and is no big deal . I will adjust tuner till it shoots one hole again then go from there,just curious what others have done. i bought it for tighter groups out at 200 plus yrds. And yes it works, on a 6in plate at 200 yrds it was shooting a estimated 2-4 in group now its shooting a 1.5 in group. Any input on what others have found would be great,gonna add this brake and retune.thanks .
