Have a question for three-gun optics. Someone else has a very similar topic but I did not want to bogart his topic, so I will start my own. Getting into three gun, something I have done exactly zero times so far. I have shot USPSA in production for the last year. I have accumulated some optics to try out on my AR. The AR is nothing special, basically I have two options, both pretty much stock except for some furniture changes; RRA Tactical Entry and an M&P 15T. The M&P is my wifes, the RRA is mine, and both of us intend to do three gun. I know there is stuff I can do to the ARs besides optics but my question centers on optics for now. I intend to shoot tactical, and I am a bit confused as under some rules tactical seems to be equivalent to limited, depending on what rules you are working under.
Anyways, here are my optic choices, obviously with BUIS being present. Questions though, on a 1-4 optic, can you reliably cowitness BUIS when the optic is set at one power?
Burris XTR 1-4/24
Millet DMSII 1-4/24
ACOG 3.5
Aimpoint T1
Primary Arms M4 clone
Burris Fastfire (the only mount I have is a ring mount that goes with the Burris)
I am thinking of letting the wife have the Burris for her gun, and running the ACOG on my rifle, at least for stages/matches with some tgts out to 100 meters and beyond. Question, can you switch optics between stages w/o changing divisions?
If we are just shooting local matches with stages basically in pistol bays, the wife can use the T1 and I can use either the PA clone or the Fastfire (I'd need to buy a new mount for it and I am not sure the Fastfire is the best option as a primary RDS, seems to be more of a backup for a rifle).
I am actually considering getting rid of the Millet as it is NIB after a warranty exchange and I have since picked up the Burris XTR. Also, considering sending the PA clone back as it is also NIB, and a recent purchase, and I made the unplanned purchase of the T1 after buying the PA. I haven't brought the PA to the range yet, but just playing around with it in the house, I do not seem to be able to acquire the red dot w/o cheek weld as easily as I can with a genuine Aimpoint. I may be wrong, and that is just playing with the PA in the house mounted on the rifle.
So what are recommendations and considerations given this lineup?
Specific Questions:
1. Are limited and tactical the same divisions under some rules?
2. Can you switch optics between stages w/o changing divisions?
3. Can you reliably cowitness BUIS with a variable optic when it is set to 1x?
4. Is the Burris Fastfire a decent rifle Primary RDS such that I should buy a stand alone mount for it?
5. Given the assortment of optics that I currently have, is the PA and Millet optics sort of redundant meaning, do I already have something that does the same job better? With selling the Millet and sending the PA sight back, I could have roughly $300 to do stuff like buy a stand alone mount for the Fastfire or purchase something else that is more suited to the options I have.
Now, to make things murkier, I also just picked up a SCAR 16. I don't think that really changes anything as it's close enough to an AR that it shouldn't really change my optics considerations but maybe I am missing something?
