But yet you didnt mention a magazine go no go.I speak from my own "real world" experiences... Like ive already posted, the parts that im saying are solid and which ones aren't are from my own personal experiences and those experiences of people I directly know and heard/seen it from them. Nobody has to follow these lists or parts. This is, as posted in the original post, my personal go-to parts list. It's not all the acceptable parts out there. It's just the ones I like to use. And a combination of the stated parts will make you a good gun.
I've got a few go/no-go gauges. I've got a few hundred different pin gauges because they come as sets, digital micrometer calipers, torque drivers, torque wrenches, erosion gauges, bore alignment rods, several specific task tools to assist in build like a muzzle device wrench, castle nut wrench, receiver extention vise block, magwell vise blocks, reaction rods, barrel dimple alignment block/ drill guides, vises, drill presses, several barrel nut specific wrenches for different types and a ton of misc tools. Im sure I missed a few but still.
I haven't really found an "armorers wrench" that I've enjoyed.
By chance do you have a uncle that lives in Southern Indiana thats a master in 100 different trades?
