The Magazine Well
Use your foregrip to locate the front trunnion. The wooden "snout" (part of the lower hand guard that protrudes into the receiver) should fit nicely between the trunnion and the receiver.
This build is going much faster and more precisely than either of my others and the reason is clear, the template. I have never found one that was 100% correct before. I must have a half a dozen of them, and no two are identical so I would measure from all of them and used the measurements that seemed right, which was a very time consuming task.
After double checking as best I could, I decided that the template was correct. I just glued that sucker on, and fired up the drill press.
Here it is all drilled.
Editor's Note: While using a drill press helps a great deal, if you don't have one, don't worry. A hand drill can be used instead. Be sure to center punch all your spots prior to drilling and we highly recommend that you step drill (start with the smallest drill bit you have and work your way up to size).

Magwell is perfect.
Not bad for about 3 hours of work, the old way took me at least twice that long to get to this stage.
