My Romanian made WASR 10 AK-47 is just plain fun. Mine is stock except for a tactical grip replacement as the standard ak grip is tiny and horrid and i don't understand why they don't just charge 20 bucks more and put the good grip on at the factory. The wood furniture heats up fast making this gun a little less than a workhorse at the range. If you plan on shooting a lot of AK without some kind of heat shield for the front stock, i strongly suggest wearing a glove. That's what I do as it makes the gun bearable to handle after 100 rounds.
After about 1500 rounds, I feel confident this gun is gonna keep on shooting failure free. I have seen the manual controls get a little sticky when it gets dirty, but the piston and bolt still crank when fired so it doesn't seem to affect the reliability of the weapon.
Someday I'll have the money to invest in a machined metal higher quality version...or even better yet..an AK-12. Time will tell.
FUN FUN FUN GUN!
