Ok, I am mainly an AR guy so don't make fun of me too badly.

Two years ago I decided I wanted to build some AKs eventually and bought 2 Childers receivers for 7.62 mm cut out for a Bulgarian side folder.  I chose to drill the trunnion holes myself.

I have recently seen the new issue Slovakian parts kits on the Atlantic tactical website.

1.  Are these any good?

2. Will I have any compatibility issues with the receivers I purchased? (Aside from the stocks which I intend to replace)
