Hal, now you just need to take one of mags and make a feed tower to go onto a 100 rd. 5.56 round drum ,Recently fiddled around with my SAR3. Solved the mag problem by using Tapco Galol mags.
One had to buy a Red Star Hammer to fix this issue.... I am not sure if they are still in business....Most SAR 1, 2 ,3 models were decent factory builds and functional.
The biggest problem with the SAR 3 was the lack of correct 5.56 magazines.
The East German Weiger's or Romanian copies were uncommon.
Century tried to use DDR 5.45 bakelite nagazines but they wete problematic. Users often tried other types and feed failures were common.
The SAR 1 and 2 were much less problematic and magazines not an issue..
The SAR rifles were in the $225 - $250 price range when first imported.
The SAR 3 suffered from trigger slap and attempts to use a standard profiled hammer was not mechanically a correct fitment.
The SAR3 bolt profile required a diffetent hammer face profile so it would contact the rear bolt face and firing pin squarely.
If not properly profiled the hammer struck the bolt tail at the bottom and often light struck the firing pin and started to open the bolt tail.
Misfires were then possible.
Re-profiling a hammer to work properly in a SAR3 is not difficult but most owners were not versed in this process.
Any AK hammer can be profiled to properly contact the rear bolt face and firing pin of the SAR3 bolt.One had to buy a Red Star Hammer to fix this issue.... I am not sure if they are still in business....
when I converted my SAIGA 12 to pistol grip and SBS'd that's what I used to secure the pins............except I didn't buy it, I made it in about 40 minutes using 28ga. sheet metal.
. Also Very easily installed a "Pin Retainer Plate". There is no reason to ever again struggle with a "shepherd's hook".
