I saw this thread when searching for something else AK related and thought I would join the fun. Im new here but have around 6000 posts on the AK on other boards. Im not bragging just want to give a little back ground. after reading the above posts I felt compeled to comment
IMOO the AK 47 and variants are possably the most under esimated gun in regards to accuracy. Most of there bad PR is due to guys shooting ammo that is garbage when it comes to accuracy potential. that and the crap trigger and poor sights.
I have built some pretty accurate AKs, I have several stock barreld 7.62x39 builds including a 12.5" barrel pistol that will shoot under 1" at 100 yard 4 or 5 shot groups. I also have a a couple custom barreld 7.62x39,s that will do well under 1" groups. they have .308 bores and tight chambers but the actoins are pretty stock. all are scoped and have tuned triggers.
I have a heavily modifed AK in 223 that will shoot SUB 1/2" Groups consistantly. I have shot Praire dogs out to 700 yards with it. The gun runs a
26" heavy varmit barrel 1-9 twist that is floated and the rest of the gun is pretty modifed. how ever it still runs a pretty much stock bolt and carrier and and it is built on a bent tapco non fully temperd reciver. that is basicaly of stock design. The pont being is the action will shoot accuratly
IMOO all this bussiness of the pistion in the gas system causing inaacuracy and all the stuff about the loose fit of the carrier and bolt to the reciver is false. MY 223 build shot virtualy the same with no gas system installed as it did with all the gas block, gas tube, ect installed In fact the the best group to date was with the gas system installed. It has shot a .437" four shot group and 5 shot groups at just under .500"
To many guys just dissmiss the AK as inaccurate with out really trying to do any thing with it. I deer hunt with a scoped AK pistol in a local pistol/shotgun zone and I have taken deer out to 225 yards ( thats really pushing it BTW ). I varmit shoot almost exclusivly with my AK varmit build. Im working on a 260 remington version currently.
Good ammo is vital to shooting getting much out of them. hand loads and load development work are critical to getting much under 1" groups.
in 7.62x39 hand loads are almost mandatory. seating the bullet out as far as the mag will allow helps and if any brass can be found that has a thicker neck it would help some AK chambers have over .012" of neck clearance and a ton of free bore. I have a custom reamer that remidys on a custom barrel build. I have made better brass from 220 russian blown out to 7.62x39.
220 Russian is the parent round of the argueably most accurate round on the planet. the 6mm and 22 PPC. winchester brass will work pretty well for basic accuracy loads. bullet selection is not great but Graff & sons have apretty good selection. going to a 308 barrel solves the bullet problem.
Here is a link to a site that has more info about mine and otheraccuracy builds with lots of good info. (i hope its ok to post it here) I welcome any one to check it out

here is some pics of a few of my more accurate AKs. the orange target was 10 shots at 200 yards
with my 223 varmit AK build while adjusting the scope during a sight in. the circle is around 5 shots with no scope adjust and the others were with a click or two to the left. had I Not been trying to get it zeroed it likley would have been a quarter sized 10 shoot 200 yard group. Many $1500 AR,s cant do this.
Most good barrel AKs with a trigger job, optics on a quality mount, and good ammo will shoot in the 1" -1 1/4" range. some will do better. MY AMD pistol amazes me from a bench. I recently out shot a guy at a range that laughed when I was getting ready to shoot at the 100 yard target. he quit lauging when I out shot his Rem 700 308 with factory ammo.
