I have a Hadar II stock coming. Now I have to figure out what to do with it...
The Hadars used milled Galil receivers, angled up in the front. As far as I can tell they were all in .308.
I'll be doing a scratchbuilt sheet metal receiver. Various Valmet models (Galils were licensed Valmets) used stamped receivers. I posted pictures of several of them on the general AK subforum. I'll use .060/.062 4130 stock and thin a spare Romanian trunnion to match, like the thick-receiver Norincos.
Somewhere I saw a picture of a stamped Valmet that showed the weld; they just bent the sides, cut a V, bent the angle, welded, then bent and trimmed the top rails, apparently. With fancy dies they could have just stamped it bent and done the top rails on the next top. Load across the weld is compression due to recoil, so it shouldn't hurt. Lots of .060 thick milled rewelds out there working just fine, too.
I need to see if I can find some of those flat, low-profile rivets some AK variants used. I'll have to clearance the stock to clear the rivets.
I'll probably dispense with the iron sights entirely and used a top cover mounted scope. A side rail won't clear the Hadar stock.
So, I expect to have a nice targetty-looking rifle with a wood stock. Now I'm wavering about what cartridge. .300 Savage or 6.5 Grendel look good so far...
