So I have had this rifle a long time. It is one of the "over stamped" SAR-3 rifles made in Greece. It is a beautifully built rifle. If you had the bolt out of this next to a Real HK it would hard or impossible to tell which is which. Compared to the later HK clones and imports this is a jewel. I never really realized how short the barrel is on this thing. I assume it was imported during or prior to the AWB with the standard HK style cage and then cut to be sold. The bolt face to the end of the barrel is like 16 1/32". The width of a fingernail over. I'd like to have a comp/flash hider on it but there does not seem to be an easy answer for that. The end of the barrel only measures .56, quite a bit smaller than the normal 5/8 thread for a .30 cal unit. I really am not sure how the barrels come out of these but yanking it for threading does not seem like its a easy task. Any ideas?
