AK bolt carrier/gas piston troubles

First I want to make it clear that I have very little experience with assault rifles in general so please forgive me if I appear ignorant.

I have recently purchased a Romanian Ak 47 and this last weekend decided to check if everything fired and fed well. My rifle fired like it should but I soon noticed that my bolt carrier felt "sticky" as if it were rubbing against the sides of the housing. (In my defense I did clean it based off of several how to's from different sites so it was clean.) After I attempted to take my second shot the rifle jammed. It ejected and reloaded another round but the bolt carrier did not make a full seal around the barrel and consequently the round. I decided to interchange mags since I have a couple different varieties but it did the same thing after the second shot.

I have a suspision that it is one or more of the following: the housing (where the trigger and action are stored), the gas piston, the bolt carrier, or the gas chamber. I recleaned it all after coming back from the range and it still seems very abrasive (alot of friction)

I am no gun smith and I have relative knowledge on other weapon systems but this seemed alittle out of my league so any suggestions are welcome. Thanks

Hmm, Does your trigger say Tapco G2 on it? What does it say on the reciever? Is this a Century gun.
Could be a bolt carrier is rubbing on the hammer. Take a look at both and see if there are any scratch marks. A good polish on both of these parts will make a big difference. It is a must on any AK. I have a bench grinder with a buffing wheel. I polish the bolts on all of my rifles.
BTW who are you assaulting with that rifle? Is there a reason to call it that? Can't one assault someone with a handgun? a 6 shot revolver? a knife? a pepper spray?
Just kidding.

I am willing to bet you may be having that dreaded disconnector failure that I had with my WASR, I can't be the only one this has happened to.

I would take it to someone who knows AK's and have them pull the FCG and take a look for stress fractures. Mine broke on the range and slam-fired the last 2 or so rounds, NOT GOOD!

Sounds to me like the receiver is pinching the bolt carrier. It can do that if it's dry fired a lot with the bolt and carrier out the rifle. The hammer will hit that pin directly in front of it and bend it forward. As it bends, it pulls the sides of the receiver inward, pinching the bolt carrier. Disassemble the rifle and see if that pin is bent any.

Huh, first time I've heard of this, but it totally makes sense. Good suggestion, jmp!
