I did this to my 7.62x39 AK...
I can't believe the difference it made...

Good idea Art! I wouldn't do this to my prebans but I would to my MAK90's. I've got tons of Holly main jets left over from my misspent hotrod days...!

PS---the bit in your 90 degree adapter is called a "Terry Bit". They are used in the aircraft industry.

I agree...
I'd never hack up a pre-ban...
I just picked up a (cheap) Russian Saiga AK, and wanted to "tweak" it...

Trigger was crap, so I swapped in all new trigger parts...
Didn't like the synthetic furniture, so I put wood on it...
Didn't like the bolt slamming the back of the receiver, so I came up with the idea of jetting the gas sytem...

Come to think of it, there wasn't much I did like about the (Hesse) gun "out of the box"
(At least the sights were straight)
I pretty much had to go over the WHOLE gun...

Did you use the terry bit for the enire hole or just to start it.?

So the way you adjust the gas flow is by replacing the screw? Interesting. There oughta be a way to adjust it by using the same screw, though - if that could happen, it would be a true adjustable gas system, and I'd be willing to do it to my rifle. Thanks for the info, and for the awesome pictures!

Now I can finally get rid of that old gas tube I was going to sleeve, along with the piston I was going to thin. Great work, Art!

I used the angle drill to go all the way through the gas block with a small starter hole, then drilled through with the proper sized bit for the 1/4-28 tap...

Whole job only took about 30 minutes...

I broke a tap on the fist try, and spent most of the time trying to remove it...
(Cheap tap)

After clearing the broken tap, the 2nd (Good tap) cut right through...

The AK gas block isn't made of hard metal, I just used a junk tap on the first attempt...
