Happy to report:
His AK shot great. Had some difficulty chambering rounds out of a couple of his mags (the bolt was sticking halfway to the rear) but after a couple hundred rounds all was well.
We had a couple funny moments, one being when we were both blasting away, he safes his rifle, runs over to me with it, and goes "Dude, my rifle is on fire or something!" I look at it and his front grips are smoking, and I started laughing my ass off, "dont worry about it until they actually light on fire bro"
Another not so funny moment for me when was I was off to his right behind some rocks, and we are both blasting cans, and suddenly my left ear is on FIRE, I cant feel the damn thing at all, just horrible burning pain. Scream a seize fire at him, and remove the commie steel case from my ear, along with the earplug that was starting to melt. Ouch! He thought it was hilarious, lol. I quickly and in an oh-so-nicely-colored way gave him a lesson in casing ejection dynamics, and how unlikle with my Colt M4 thats makes neat piles of brass, his communist rifle likes to spread brass/steel over a 20 foot square area, and launches the casings at least 5-15 feet.
All in all a good day, he was impressed how my 5.56 can throw the cans I hit about 15 feet in the air, and how his 7.62 tends to just cover them in dirt once it passes through them, heh.
