Solid & Versatile
I used this in an armorers class for both Glock pistols and AR platform rifles and now at home. Myself and my fellow students found it a good, solid platform for a number of tasks that were doable without it, but much easier with it. For example, disassembling the firing pin assembly on the Glock can be done using the slide as a jig. This block is far more stable for that task. Installing the gas tube roll pin into a low profile gas block was similarly much easier with this block than without. My only complaint is that many of the holes and cutouts aren't labeled on the block itself, so being new to it, I kept having to refer back to the included paper description. I'll cut that out, laminate it and find a way to keep it handy.
