Look. I realize you have a shop, that has nothing to do with it.
What I'm trying to tell you is there is there appears to be variance from gun to gun on the size and style of the stock handles, this effects how it locks into the bolt. Just because it works on your gun, there is a posibility it may not work on others. Before you kick into production, you may want to send a few out to test on other guns to be sure that this issue wasn't just isolated to mine and Kyle's 712s
I'm trying to tell you what we went through, and hopefully something you can avoid.
That's a valid point, the older models vary in other ways from the 2013's models. And so on and so forth.
