Sluggish cycling on yugo under folder. Polish hammer?

[mutt]

Finally got a chance to take my new yugo under folder out and while it functioned flawlessly, I noticed the bolt cycling was a bit sluggish. The difference in cycling speed was quite noticeable compared to the SLR107 I was shooting too. The yugo's bolt will hang up on the hammer pretty easily (when hand cycling) and I am assuming that is the main culprit for the sluggishness? I figure polishing the hammer would help. Am I on the right track? Any other areas I should polish? I was planning to use a dremel tool with a polishing attachment and some polishing compound. Is there a better way? The rifle has a Tapco G2 trigger group and a nickel plated BCG.

Is it made on a matching parts kit?What receiver are you using?
Hangup on the hammer when cycling by hand is normal.Sometimes it feels like it has a bolt hold open feture-no worries normal function.
If your using the tapco g2 it would be a good idea to polish it.I've sanded them down with 1500 g paper then buff out with dremell and polishing compound.
You also should check the depth of the disconnector spring-there was a known issue with the tapcos a while back

But for the most part sounds to me you just have to wear it in.The only other thing I can think of that would make it a bit sluggish is if your using an American made barrel as opposed to the Yugo made one is that the gas hole might be drilled a tad too small.
If after a couple of mags through it it still poses some problems ask BP tactical for help.

It's actually all Serbian, made by Zastava (N-PAP). Receiver, barrel, BCG, stock assembly are all factory. Only American parts seem to the required 922r crap: FCG, some furniture, slant brake and gas piston.

Cool. I was wondering if that was the case as well. Guess I'm used to Arsenal AKs that are a bit smoother cycling right out of the box. Thanks for the info. I'll check the disconnector spring, give the hammer a good polishing and call it good.

I wouldn't worry about it as long as it is not malfunctioning. Shoot it and it will smooth out on its own.

Don't take too much of of the top of the hammer, too much and reset becomes spotty.

Also if you take too much of it could ruin the heat treat on it and cause the hammer to mushroom.
