Try this

Standard mil-spec 7.62x39 is 124gr @ 2330 fps.  I think the BC of those bullets are around .250.  Sight height is ~1.5", IIRC, but it will vary depending on your sight.  

FWIW, I zero at 25m because that is useful for me.  YMMV.

There isn't a good zero that I've found. 7.62x39 just has too much arc to it to have a good point blank-250 yard zero like 5.56 does. Either zero at 100 yards and know your hold-overs or zero at 250 and know your hold-unders.

I asked this over in the ammo forum and started a mini shit storm.

I'm getting a 5.45 now so I quit caring (very similar trajectory to 5.56)

I was actually wondering about this the other day.

I am bout to throw a red dot on the sar, and I was thinking 50 yard zero, then I assume a slight hold over for 100 - 150 yards.

I ended up going with a 300 yard zero on my SLR105 with Konus red dot and SGL31 with PO 3.5 optic. Today I was nailing about 90% hits at 300 yards with both.

The Krink has a decent 100 yard zero and I had to use some hold over at 300 but not much, I'd say aiming at the head or neck and getting chest/gut hits at that range.


I have a 50 yard zero on my SGL31 irons and could hit a fullsize target over 90% of the time using irons at center mass at 300 yards. Dude would probably have no knees left but at least I know a center mass aiming point is going to score hits all the way out to 300

What is a good distance to zero a kobra on a SAR-2? My range allows 50, 100 and 200 yards. Can the 5.45 be zeroed at 50 yards for similar results to the improved battlesight zero for the 5.56? Or should I follow the manual and zero at 100 yards? Thanks!
