Thanks guys, as you can see it is a lot of work to do. these are labor intensive guns to produce and when doing over 20 at a time, it takes a while. Even though I have done over 200 of these so far there are still unexpected problems that lead to delays, like having to spend several extra hours removing the barrel scrap form the US barreled kits.
This coming week I will be starting the lowers, there are several machine operations to do on these as well as fitting the semi fcg parts. this will take several days.
