The front and rear sling mounts are on opposite sides for one, which I don't care for but the fact that the swivel is on the front of the stock rather than the rear, it makes it very awkward for anything other than a traditional sling.

It is like that because the stock folds, or else it would bind up withe stock folded, and it was designed for that sling, if you want something more tactical you can get russian 3 point or single point slings. The sling is bombproof and comfortable though. It was made to never be tooken off the rifle so you wont lose your rifle and i agree with this belief. I have a magpul ms3 on my ar and its cool but is is toyish in comparison, im sure i could break it if i tried alittle and it is rediculously bulky, i dont need to quick adjust it is just silly.
I just put the sling over my head and have never had a problem, over my back when i walk far. But whatever floats your boat i get people like different stuff.

I really do want an ak. They're cool as hell and I love the simplicity for combat enviroments. It's a 3 part field strip! How easy is that! Cheap ammo and mags that's fairly accurate for a fighting gun. The nostalgia of owning and operating one is kick ass too.

Do you guys prefer the ak 100 series folders over the triangle folders?

I know I want: high end stamped ak 47 or 74.

Arsenal slr 104 or 107 are my choices, along with rifle dynamics rd series.

Besides mag cost, it seems the 74 is a better option in my opinion. I like being able to carry more rounds than 7.62, faster follow up shots, and it's the same cost as 7.62.

I'd rather have a triangle folder myself for aesthetic reasons and also because recoil pads are available for them to extend the length of pull. Pads for the 100 series folders are as rare as hen's teeth.
