You say top quality, the Ak scene is highly subjective, the Valmet usually on the top of the pile, but, you got China who built them slightly heavier than the European counter parts, thicker receiver, heavier barrel, basically an RPK in Ak clothing and what not.
Then you have the early '80s Egyptian built on Russian machinery. Oh, then there are Bulgarians and Polytechs with their fully machined receivers. Some of the Hungarians are decent as well, as are the Izmash Saigas and Veprs. Maybe lump in a Polish.
Then another question....caliber, just in x39 or...... a Yugo M76 in 8mm, a Romanian PSL-54c in 7.62x54r, NDM-86 in 7.62x54r, Saiga 12 or 410 shotgun, the Vepr in 308, an Arsenal SLR 106-31 5.56mm or the SLR 104-33 in 5.45mm, and if money is no problem the Russian SVD-63(pure sex right thar
And all the cool letters and numbers...SA85, SA93, SLR95, SLR96, MAK90, NHM90, MAK91, NHM91
And to throw a wrench in the machine, cause I'm that kinda guy
, the non-Ak variants, the bastard children, the IMI Galil, the Vz 58 and for the giggle factor the South Korean Daewoo K2 assault rifle and K1 assault carbine
It's easier to ask which to avoid like the MISR-90 or early the WASRs.
They all have their pros and cons, in the end it's a simple effective platform and any of them are fixable. Most all, with the exception on a few pre-ban ones were built here from parts kits, their quality is only about as good as the monkeys drilling the holes and behind the rivet guns.
