You have to drill two holes in the rail and drill and tap one hole to install a non-folding stock on your Ventilator.
First picture is a non folding stock with AeroCrank.
Second picture shows threaded insert (there is one each side) that needs two holes drilled in the sides of your rail.
Third picture is hole in the bottom of the stock, front of the slot for the trigger. The bottom of the rail must be drilled and tapped for the bolt that goes here.

For the sides of the rail you will need two 8-32 x 1/2" screws. I used hex button head stainless steel screws. I could not find a source for Torx button head Ti screws.
For the screw in front of the trigger slot, you will need to drill and tap your rail for 10-32 bolt. You could reuse the Ventilator bottom bolt. It is 1 1/4" long. Check and make sure it's not too long. I used a 10-32 x 1" stainless steel SHCP (Socket Head Cap Screw), again I could not find a source for it in Torx Ti.
The Ventilator's lower butt stock screw is behind the trigger slot.
The Ventilator butt stock (sides) uses the same screws that also go into the trigger/latch box. These might also be too long without the folding stock. I used stainless steel hex button head screws, 10-24 x 1/2" since the heads were a little lower profile than the stock screws.
With a non folding stock the Ventilator safety will seem to stick out to far. It can be left "as is" Or cut shorter. If cutting the shafts shorter, be sure to have the smaller OD "step" (by the threads in the center) machined on. Or you can cut the knurled heads of and machine the ends. The ends could be machined as simple as a 45° bevel, or machined as a rounded end.
Your Ventilator could have either a brass or stainless steel (maybe Ti?) safety, depending on the year made.
Picture is both brass and S.S.

I am not familiar with the Firenock folding foregrip. Your Ventilator forearm can be used with a non-folding stock.
