need help to id ak barrel no gas port

[trotsky]

It's probably a PolyTech that came with one of their "full parts kits" about 6 years ago? Those barrels ere undrilled, though the parts were pressed on (have no idea why).

This is a good barrel for a Chinese AK - bet Informer could mount it to a receiver for you & do the required gas port drilling...

i have a threaded pre ban ak barrel with no gas hole port only marks says china on rear sight.is it possible to drill hole and what size?

[slapshot]

The barrel in question is mor e that likely a Poly Tech Barrel. The Site housings and gas block were installed at the factory. The gas hole is drilled thru the gas port. There is a Starter hole inside the Gas Block. I don't remember the hole size in mm I would just convert it over to a Number size bit.
I think it was 5/64 or 7/64, i'll check and e-mail later.

Those barrels didn't have the f.sight ,gas block, or rear sight pined, or holes drilled for pins either ,I think.Have to do that first.
I read here that you can just drill it through the hole in the gas block,being carefull not to hit the other side of the barrel,but what about burrs?How would you avoid or deal with them?
