Fix It Sticks and Borka are without a doubt the best and most utilitarian for what you need. You will pay for the privilege, but the investment is worth it.
I’ve seen people break screws with Wheelers because they lose calibration quickly and they’re not terribly precise. Had one guy warp the housing of his RMR from over-torquing. The problem I’ve seen is at the low end of the range where lighter adjustments of 9-12 in-lbs is necessary and the wrench can’t get that precise consistently. When you’re dealing with values that low, you have to be spot-on. I’ve used Wheeler and I was not impressed, but then and again, I own a Borka set and in our armory we use Fix It Sticks. This is coming from a major metro LE agency armory perspective where we see RDS pistols, patrol rifles and sniper rifles coming in regularly for various services, including issuing pistol RDS to every recruit academy. Granted- we have the volume to mandate using higher end tools.
