What's the rib width on a 3020? Thanks.
Interested in this too, as I'm hopefully picking one up tomorrow and will want to put a set of rifle-style sights. only thing I can find online says "topped with a 0.245" diameter ventilated rib...". The fact that they referred to it as "diameter" makes me question if they actually know what they're talking about. I'd like to hear from someone that owns one and can actually go measure it.
I had a set of the tru glo pro series on mine last year, the ones that fit were the 6mm. I believe the model # is TG944C. I have 2 used sets of these I'd make a good deal on them if anyone is interested.
Just got my 3020 and looks like 6mm is correct, but eyeballing it, 1/4" looks the same (although 1/4" is only 6.35mm, so it'd be hard to distinguish)
Mine is .24 inches or 6mm +- a few hundredths
Didn't like the vent rib mount had mine drilled and tapped
This I the finished m3020 drilled and tapped with a fast fire 11 and cerakote paint job and Rob Roberts 572 choke
This is the mount you will need Burris #410333 .
