I have had 3 AK's
One I reworked myself at home, a Century from "back in the day."
Although I put some small time and effort in the rifle I sold it in frustration falling in to the AK's are crap crowd.
10 years later wanting to try again I went to Atlantic Arms.

I purchased a RJ132 AK47 "type" rifle that was acually a Saiga reworked to a AK configuration. These rifle are built in Louisiana by the folks at Red Jacket Firearms. ( Sons of Guns show)I got a fairly good AK that had all of the bugs worked out by a professional.
FCG was improved, cant worked out, decent furniture and it has yet to fail to fire in about 1200 rds. It consistany shoots a 3.5 inch group at 100m. In my opinon it is one of the best buys for your money out there.
Since then I have purchased one more AK an AK103, it has AK 74 look with AK 47 internals.

It too is a great rifle. It has yet to give me a problem with about 900 rounds through it. shoots slightly better than the RJ132, but I bought it used for about the same money I spent on the RJ132.
When I had questions about my used AK 103 I wrote the builder and within 24 hours he had copntacted me on the phone to discuss the rifle with me as the SECOND owner. He obviously cares about what he builds.
Since then I have done some mods on both of my rifles.
On my RJ132 I installed a Ultimak scout mount rail that replaces the gas tube with a gas tube and a rail combination.
I also installed a Bushnell TRS-25 red dot sight. This is an inexpensive and good value in red dot scope that when used with the Ultimak allows you to co-witness your iron sights.
I also installed a US Palm "battle grip" pistol grip to replace the stock AK. It is more comfortable and allows easy carry of a boresnake.
I have also modded my Safety to be quieter and easier to employ.
I am doing many of the same mod's on my AK 103, a little at a time and enjoying my rifles as I learn and shoot them.
BTW, if you are willing to devote some time to work your AK's you may soon prefer them to AR's. As a retired Combat Arms Soldier I definatly prefer my AK's to almost any of the AR's I carried in the Military.
I guess my point is, go with a good base model AK and build it a little as you go. They are great rifles and you can do most of the work yourself.
Thanks
