I took my SAR 3 and AK sight adjustment tool over to the range to sight it in at about 25 yards. It was a lot of fun and zeroed in quite well.
The rifle came with what I believe is a modified AK 74 mag (done by CAI), but it only feeds well with about 20 rounds. I bought some Bulgy AK 74 mags and loaded them each with 20 rounds (I didn't try to load more than that). They worked really well and I didn't even have to mod them! The mags only cost $10 each. I also took some Bulgarian "Circle 10" 5.56x45 mags that I moded by filing down the back a bit. Those work the best. No feeding issues at all. I really like my Romy SAR 3.
