Great 13” Allen screwdriver
Does a great job for its intended purpose. It’s doesn’t have the best quality handle, but still perfectly suited for tuning the gas block hidden behind a mile of rail. It torques a little, but that is to be expected with metal that is so long and so thin. It does the job great. The handle is my only minor gripe, and that’s just being picky. The good thing about the length is that it puts the handle in front of a long muzzle device, and 18” barrel making it a breeze to adjust the gas flow. I would highly recommend this product to anyone in need of reaching a gas block that’s tucked away.
