Layout guide really works great, holes are dead nuts accurate. Great inexpensive and simple solution, and very fast.
Totally invaluable tool for building on blanks. It truly does eliminate the need for a stupid paper template or an expensive drilling jig.
Guide is great. Works well. But dont be stupid, get the layout punch, it also can double as the spacer for your bolt guide rails!
I ordered one of these, I still used my template under it to make sure. There is no need for a template if you set this up correctly. All the punch mark came out spot on with this guide. just need one for the trigger guard now. then we can stop fighting trying to glue on templates and having to clean it afterwards.
