Texan carbine with mad dog stock

[rctk1]

I can't find any videos or instructions on how to install a mad dog on a texan. Is it a direct drop in or do i need to mess with alot of the internal to get it to fit right

Drop in. The screw in the grip is just a bit finicky because the capture "nut" can rotate but the stock has a hole so you can align the "nut" while tightening the grip screw. 

The front screw that held the forearm piece originally can be tightened too much and if it is it will lock your power adjustment wheel so tighten it gently.
