Hi
Anybody tried this combo, want to try the KS Arms Action 3 Lugs, however MDT doesn’t recommend 3 Lugs action on their 6BR Norma mags unless Some tweaking done on the mags. I’m still on the parts gathering stage, so no final decision yet, Tenacity is my other option which I have 2 and very happy with it, can always use one of my Tenacity/ 308, for the 6BR, but I just don’t switching barrel . Opinions please
 
MDT has the disclaimer, but I call shenanigans on them. The 6BR MDT mag works perfectly fine in my Terminus Zeus. I will say that, if I run the mag very high, forced up into the action until it hits, then I can't run the bolt forward. So I just let the mag have a bit of slop vertically.

The only guy I know running 6BR cartridge in a KS 3lug, uses the double stack style 10round magazine.
 
I stayed away from 3 lug for my 6BR (I use MDT mags), I ended up going with an Impact (2 lug 90 degree) and it feeds great.

I also have a Zeus 3 lug on my practice rig and it feeds 223 great. I really like the 3 lug 60 degree actions and have an itch for a KS, if I ever build a dedicated F Class rifle it will be on a KS of some kind (caliber dependant).
 
I run a KS Arms SAR 3 Lug in an MDT ACC with the MDT 6BR Mag and have no issues whatsoever. I was also a shade torn on this but Mike at KS Arms straight up said they designed this action to feed the 6BR and its variants reliably from these mags. And he was 110% correct, i've never had an issue with feeding. Feel free to fire me a message if you have any questions but I can speak from first hand experience. Also, I would HIGHLY recommend their barrels. Mine is a 6mm 7.5t MTU. Dennis at Go Ballistic did the work. The photo below is 3 shots at 500 yards off the bag in photo 1, measured roughly 1.3" with a 107 SMK and Varget with Lapua Brass.

Don't hesitate on the KS SAR 3 Lug action, I have that and a Tenacity and the KS is where its at. Go Big Tactical has 15% off the KS 3Lug right now till tomorrow I believe. I thought about grabbing another one at that price for a future build.

Now that’s encouraging, I already a barrel ordered from them a month ago same profile snd twist as yours. Actually mike just answered my inquiry and told me the same thing, no problem with 3 lugs and MDT mags. Now let see if its on sale at GBT. Thanks

You have to add it to cart, then click "redeem code/coupon" or something along those lines. And enter EMT15 and you'll get 15% off but gotta e-transfer to pay.
If you want to use CC use CC10 and get 10% off instead. I think that sale/codes expire tonight at midnight or tomorrow at midnight I cant remember. Im really debating ordering a 25 creed PVA prefit from them for my SAR and have it fluted, cerakoted and thrown into a lighterweight stock for hunting season. at 15% off it its cheaper than buying a whole new rifle lol

Is the KS 3 lug a single ejector or dual like the deadline? The sale price at gobig is tempting. Probably end up getting a barrel for my coup de grace.
