SAR-3s are a unique breed of AK. Your best bet may be Red Star. As you get more into using the rifle, if you experience problems with the magazines, it may be that you do hot have Weiger mags. They are probably the only .223 mags that work reliably with the SAR-3. Century International and Copes Distributing sold Weiger mags at one time but the mags are getting hard to find and cost about double what a standard 7.62X39 mag costs.
No guns, no peace.
Know guns, know peace.
