I have an Ak build (Bulgarian SA 93 parts kit) on an Ohio Ordnance receiver.
I was shooting it yesterday when I noticed the bolt would stay back when
I loaded it.  It fired with out a hiccup except with the promag.  

Any ideas?  Is it the springs?  Lousy build?  

The guy that assembled the gun for me was a novice, so I sent it to a guy
in Arkansas to fix it.

Usually the bolt just hangs up on the hammer when they are new.
It should wear in and stop doing it.
Don't count on it as a "feature" and watch that it doesn't slip and slam home on your fingers.

A little more info:

Just about every AK made will hang up the bolt if you ease it forward.  This is just the spring force of the hammer pressing on the bolt and bolt carrier.
A slight bump on the bolt handle will close it.
In any case, there's no reason to ease an AK bolt forward when loading.
Pull the bolt all the way back then LET GO and let it run forward on it's own.  "Riding" a bolt causes failures to feed.

However........
If the bolt is sticking open when it's fired, that's a different story and you have a serious problem that needs to be checked out to find the reason.

Thanks for the info.  The bolt does not stay back when firing.  I have not fired it too much.  I have maybe 400 rounds threw it.

Lube the entire bolt, rails on the carrier, top of the hammer that contacts the carrier, and the rails in the reciever.........I just started using a product called Rand CLP and my action is literally like its gliding on ice......I cannot believe how smooth it is.....look them up, you can register for them to mail you a free sample on their site.

Don't ride the bolt.

Not on you AK or any other semi-auto gun you shoot.

I've used OOW receivers with tapco G2 triggers. Of the 6 I built, all of them required taking some material off the hammer where it rides against the BC to get them to work without hanging up.
Tapco makes their AK hammers a bit over sized (tall), so that they will work in about any receiver with some fitting. I think the holes in the OOW receivers are just a tad high as well which exacerbates the problem when using both.
If the BC is hanging on the hammer excessively, I'd grind a few thousandths off the hammer's face, putting a bit of a radius on it as well. Lube it up and you should be GTG.

AMD65 on Hungarian receiver, built at FEG, and it hangs if you ride the bolt assembly. Still 100%

As said, don't ride CH's. As far as Tapco's G2 and grinding... no idea if the parts are hardened, but if so, then I wouldn't grind on it.

It is a k-var trigger.  The gun runs 100%.
