An 80% lower is an 80% lower! The bang is how good you do your 20% part.
So the cheapest are as good as the more expensive??
Yes as far as I am concerned they are. But I will say this My buddy bought the 5D Tactical jig and it is the best I have seen. I had the 80% Arms jig, it was good but not as good as the 5D Tactical. My suggestion to anyone wanting a first class finished product is to either use Marginless Drill bits on your holes or a step reamer. I have used both Marginless and step reamers. The holes are perfect either way. I hope this helps you out.
Unless you just want an unknown lower, I would personally just buy a matcher set from Seekins.
