Those Tapco side folders century puts on the WASR look pretty crappy in person.
I have a German set as well--I put a rail on the bottom of the of the bakelite lower, I can mount stuff to it...I was hesatant at first-- but my bipod can use the weaver rail to... its the best way to attach a bipod to an ak, I get real serious accuracy with the set up....my little rail is only an inch1/2 long so its not to abtruseve. I wouldnt even consider really using a wood lower -- the german bakelite works great, and the set cost me 19.00 bucks.
