I'm back. The thing I don't like about the Choate is that they moved th pistol grip to far forward. If you like to sqeeze your trigger with the tip of your finger you will find it a little uncomfortable. But having said that, it's the more comfortable out of the box.
If you like to customize things I like the ATI better. I like to customize. The first thing I did was take a double cut file and hack a bunch of material where my thumb goes on the pistol grip, on the upper side. Then I filed the pistolgrip with the half round file were my fingers went. Rounded the corners.
I also cut the forend where the top 3 slots are. I cut the stock along the bottom edge of the top slots. I used a vented metal hand guard in place of the original.
Where the back of the reciever meets the stock they didn't gap it so you can remove the reciever cover. I cut the stock off even with the top of the reciever(with reciever cover removed). Then I notched the stock So the cover would come off.
The other thing I did was to cut the stock a little shorter for me. Which you probably won't have to do.
Then I finish sanded it and gave it a cammo paint job of my own.
The Choate doesn't need all that work. But I don't like the shortened trigger pull distance.
Which one do I shoot the most ? Hands down the ATI one. But it also is a D model so 30 rd AK mags are more fun than 10 rd strippers. The Choate one is a a regular SKS.
My conclusion: If you want to put it on and shoot, or have short fingers, go Choate. If you like to customize things go ATI.
P.S. TAPCO has a new SKS stock. It has the M-4 calapsable and SAW grip.(check out the AR15 vs AK47 thread in Gen. Disc. for a pict.) Not sure on a price.
