I had the same setup many years ago, except mine was a 7x magnifier. I'd give it away to a buddy. It won't hold zero. The magnifier rock back and forth, making the red dot move side to side. Replaced with a Vortex Strike Eagle 1-8x24. My newest build, I have a Holosun HS403c and Holosun HM3x. Never going sightmark.
It will def work with all three. Question is. Which caliber fo you strive for greatest accuracy with? Thats the one for this trigger! Good luck and let us know how it works out!
I have a DB10 and happened to watch a vid on a DPMS. Had never heard of this platform which is what brought me to this vid. The DB10 is a hybrid of the AR10 and LR308. I even emailed Diamondback abput what their rifle was classified as.
A lot of 1:8 higher end barrels for more refined less "duty" oriented AR-15s recommend higher grain rounds for better accuracy at range from what I've seen. Criterion, whoever Radian uses, JP, etc.
1/7 twist is most common is pistol caliber and SBR rifles with barrels under 10". So 55 and 62 grain is just fine, considering shorter rifles are not used for over 300 yard shots typicly. Most people keep their shots within 100 yards.
