I like the Korba sight, I haven't seen many people use in on the utilimak mount. I noticed the magpul AR mag too. Tell about the guy using the Romy drum? I would think the added wieght would be a draw back, not to mention noise if you where in a situation that calls for discretion.
It is AWESOME for breaking contact, and counterambushing. I wouldn't do a foot patrol with one for the weight and noise as you said, but for a vehicle convoy (Which they just bailed out of) it is GREAT! -Ultimaks are GREAT, I use one.
Some Aimpoints with the low pro mount will allow for co-witness. What set up do you run? Any of your students running the Arsenal SLR-106? It is an AK in 5.56.
I have a MUCH abused WASR with a Eo Tech with throw levers on a ultimak rail, a Blue Force gear single point sling, and a Pentagon light. Now that XS big dots are avalable for AK's (I have one on my 74 that I now use for training) I am considering putting a H1 Aimpoint on my WASR and installing Big dots. No students have ran the 5.56 AK's WHILE I have been here.
That's a close up, there's 9 or 10 guys on a line, and they are bounding by teams of 2's. (First day) There are several guns firing at all times.
