X2 for learning. He is spot on!
I recently had my 6-284 on a Rem 700 finish up and though it is and awesome looking varmint killing machine I have nearly the same amount invested in it as I would if I were to have gone with a custom receiver.
In fact, if I would have sold that donor rifle and added that money to what I spent on my 6-284 I would have been within a few hundred dollars of my full on custom 338 Lap Imp built on a BAT HRPIC with a Lilja, MCM A5 w/thumbwheel adj cheek piece and Jewell trigger.
You can certainly spend less than I did on my Remmy built 6-284 but if you plan on spending the money to make your Edge project all that it can be you will be close to the same money as it would if you bought a custom receiver and it will forever be a true "custom rifle
" not just another Rem model 700 that was customized.
