Planning on building an hk11A1 from a parts kit. What legality mods are required for a semi build? I searched and apologize if my Neanderthal poo poo brain missed anything already walked through.

The first mod I know of on my HK11A1 build from MM was that on the bracket that the grip stick rests on, there's a block welded on and then a slot cut in the grip stick and trigger pack. That way you can't use full auto packs. You'd also need the typical mods for any SEF pack. Those were at least the ones I could easily notice. I'm sure there are more.
