The Procedure
What I did was use the ACE adapter as a mount for the pistol grip, simple enough:)


remove the existing stock
insert reciever adapter may need to tap it in with hammer and pry it out
material needs to be removed for adequate clearance of rear trigger guard rivet
when you remove the adapter you can see where you'll need to clearance it, make a dimple with a drill bit or a channel with the Dremel
Make sure adapter can be inserted without too much force, it will be snug still
mark center of hole where the buttstock used to attach on bottom and use the #3 drill and tap for 10x32 NF hole, ACE provided me with extra screws so you can use one of those or you may have to pick up a countersunk screw
Although not necessary, I drilled the receiver so I could use the holes tapped in the sides of the receiver adapter, slide the adapter part way in to determine the location and use the 11/64" or 3/16" drill bit for the holes. I wanted the adapter held as securely as possible to the receiver.
Now for the tricky part the PISTOL GRIP STUD
I made a template from my FAL rifle to get the proper angle of the stud

the PG stud is angled back 80 degrees
this is where having access to a drill press and vise would be helpful although with patience I imagine it could be done by hand
mark a point 7/8" back from "lip" where adapter steps up from where it goes into reciever, this is the aproximate location of the PG stud, you will probably want to check for yourself as to the best location on your gun, put the adapter in the receiver and put the grip where it should go, and use a drill bit down the hole to make a slight mark, I don't think it has to be perfect, like I said on mine the setback is 7/8"
once you have determined the location of the hole, it must be drilled with the #21 bit slanting to the back of the firearm 10 degrees from vertical

try to keep your drilling centered so your stud doesn't end up angled side to side, you just want it angled back!!
Tap the hole with the 1/4x28 NF tap, TAKE YOUR TIME go slow and back it out often to clean out chips, keep it oiled
the aluminum will gall up easily and you won't have sufficient threads.
after tapping, apply locktite (or JB weld if the threads are loose) to the section of all thread and screw it in, you may want to pick up another 1/4x28 nut and jam them together to help screw in the stud
slide the PG over the stud
time to fit the PG, file the grip to clear the "step" between the receiver and adapter
remove some material from the rear of the grip so it doesn't hang over the adapter

once you are satisfied with the fit, trim the stud so that 1/2" protrudes through the hole down inside the grip
install PG with nut, or nut and washer.
Assemble stock to adapter, or stock to folding mechanism then to adapter.
DONE
Like I said in my other post, this is a work in process, I plan on doing something different for sights eventually, a muzzle break, etc...
As far as the front end and charging handle

I filled in the checkering on the sides with epoxy, and used a drill, Dremel, and file to make the slots, and then covered it with Duplicolor spray can truck bedliner (looks good, and has a real grip to it)
the charging knob is from an Israeli Galil, I cut the stock "lever" down so the Galil know would fit and welded it on.
Thx All, and Good luck!!

PS: I used a modified G2 single hook trigger group set to get the parts count up.
