One Cartridge Two Zeros: SIG Romeo 9T (ad-free)
Added 2023-01-23 12:01:00 +0000 UTCMy full SHOT Show roundup is available for Patrons here:
In its continuing effort to provide everything for the US military from shoelaces to fighter jets, SIG has developed an optic which resolves a challenge with .300 Blackout and other calibers which offer both supersonic and subsonic loadings. Namely, how does one zero an optic for such a rifle? SIG's answer was to build a red dot optic with two separate emitters, each creating an independent reticle. One is green and one is red to easily keep track of which is which, and they are each zeroed independently. A single button cycles between red, green, and both on simultaneously.
Beyond basic durability and waterproofness, a number of other military concerns are addressed with the Romeo9T. Its emitters are positioned vertically, and the glass is designed to prevent any light spillage out the front of the optic, where it could be seen by enemy forces with night vision gear. It also has an emergency brightness feature - tap the main button once and the reticle jumps to maximum brightness (a second tap returns it to whatever the previous setting was). This is to allow rapid adapting to brightness when using NVGs. Moving from darkness into a lit room or having outdoor lights come on will render a reticle set to VNG brightness completely washed out and invisible, and this feature allows a quick solution.
The price is expected to be (IMO) eye watering, probably because as long as it's the best (or only) option, military budgets will pay for it regardless.

I shoot 300 BO (suppressed, what the heck other reason IS there for the cartridge to exist!) out of a Remington 7 AAC bolt gun. https://www.thetruthaboutguns.com/gun-review-remington-aac-model-7-300-blk/ I have topped the R7 with a Russian Federation produced fixed power 8x56mm 30mm tube scope having very low output LED illumination for bottom settings and the good old (USSR developed) multiple "chevron" reticle. Net result: I have shot wary predators at 25 to 50 yards under no moon, total overcast conditions using only the ambient light reflected off that cloud cover from a town 5 miles away. If there is ANY moon or even bright star shine, I can generally see to shoot quite well out to 50 yards +. If there is SNOW? Or more than a "new moon"? 100 yard shots are easy. Subsonic and past 100 yards, ballistics and velocity prevent sufficient certainty to pull a trigger as animals WILL move when THEY like and the trajectory is "over the rainbow". I have fired enough 220gr. subs and 150gr. supersonics (Ca. 2100fps) to know WHICH Chevron to use with WHAT load and WHAT range. God help me if the targets are ever trying to kill me back and adrenalin enters the picture. I'll certainly screw the pooch- But for carefully planned ambushes of predators with no thumbs, it works. And it was CHEAP. If the "predators" ever develop light amplification optics of their own, it is totally passive. If technically proficient predators are scanning for RF emissions from unshielded digital electronic devices, it's not emitting those signals either Scope uses 2 cheap alkaline button cells for over 48 hours of reticle illumination. There are no tiered menus to hunt through and choose scope/reticle functions from and get lost in. Your milage may very. We make no written or implied warranty of suitability to your applications. See fine print. Eat lots of carrots and give your eyes 15 minutes of acclimation time to ambient light levels. DO NOT look at your cell phone screen while lurking and fry your night vision. (Hell, anyone who carries an unshielded & powered up cell phone while hunting sophisticated predators is going to die PDQ of a drone strike anyhow). Look at 8X56mm night scopes from Zeiss, Swarovski and Meopta to confirm this technique...

2023-01-24 05:42:15 +0000 UTCwork fine in my ar15, though supressed the supers cycle way fast... also i have a holosun acss reticle that works for both super and sub with a 50 yard zero... though you have to remember 2 dope sheets

2023-01-23 12:44:35 +0000 UTCThis is all cool, but isn't the recurring issue with super/subsonic loads that they have such different pressure profiles? I was under the impression that AR15s struggle with running. 300blk super and subsonic, without an adjustable gas port.
