I run dry fire drills with my AR15 to simulate failure of the Aimpoint.
In the event of “activation” of the BUIS (MI model) do I use my pistol grip hand to flip the BUIS up by the windage knob, or do I maintain my primary hand and reach over with the left hand and flip it up? I want to get it right before I train wrong.
Anyone else train for Aimpoint/EOTech failures? I clear the weapon, ensure no hot mags are nearby, turn the H-1 off, charge the weapon, safety on. Drill is to flick safety off as bring unto target (ready up), recognize Aimpoint is dead, flip BUIS and engage. Is that sufficient?
It seems that if you do that drill enough, you might ingrain it so that when you present the weapon you automatically deploy your BUIS.
IMHO you need to keep your hand on fire control. THis gives you the ability to continue to put rounds down range if necessary.
Also flip your front first then your rear. If you flip the front first and must engage a target you already have a so so aiming device of the front sight and your aimpoint can act as a loose rear aperature.
I would keep my hand on fire control too. I like a fixed BUIS and keep my flip up Troy rear up all of the time. It is all preference though as you said.
I run EO-techs (so i guess i really need to use a BUIS :D)
BUIS clutters up, IMHO the sight picture and distracts me. Not only is this cosmetic (i think this is the right word) but it also effects my performance.
Having a BUIS up gives me one more thing I can inadvertently shift my focus too. I would rather just see my target, and a 1moa dot with 65 moa ring.
Also I run a flip up magnifier, so there is no room for a rear BUIS.
Yea I used to think that :sarcastic: I have a Arms #40 folding BUIS setting in the box. It used to be on my rifle Once I tried the fixed with the lower 1/3 set up ditched the ARMS #40 and haven’t looked back. The rear sight DOES-NOT clutter the view I don’t even notice it unless I change my cheek weld so that I can use the BUIS. The very top of the rear aperture is at the very bottom of the aimpoint the front sight sets way higher than the rear. And when focousing on the target the rear completely disappears.
I also have a buddy that has 3 eotechs he constantly on me to sell my aimpoint set up.
“Best practice” is totally subjective…and ultimately irrelevant.
The OP’s question wasn’t whether chocolate in peanut butter tastes better than peanut butter in chocolate. Ergo, the answer to “which hand should I use?” is not “Why, the Mets won the '69 World Series.”
Instead of making up your own questions to answer, answer the one that was asked. Think Fight Club, rule #5: “One fight at a time, fellas.”
I have a standard F-marked FSB for the front with a lower 1/3 setup.
Based on a quick read of the responses it seems the correct answer would be to use the non-trigger hand. The design of the MI BUIS is more suited towards reaching over the top of the weapon (almost like a speed AK reload) and flipping it up, grasping it by the windage knob.
I was always taught to use me weak hand. As a general rule always keep your strong hand on your weapon whenever possible… As stated work from the front to back…
+1 to offhand. I only have rear BUIS, but I’ve gotten to the point where I can pop my MATECH BUIS in a smooth motion with my offhand, with a quick rear to front motion.
I will answer this one with what I feel is correct, despite the question. Run your irons in the up position.
If your target shooting and your optic goes down no big deal. But if your looking through your optic and need that time to fire to save your life and there is no dot, do you really want to chew up that extra time flipping up your sights with your life on the line? Even a .25 of a second can be a lifetime when that oh shit moment happens. Of course many will say just point and shoot if necessary while indexing your weapon using the tube as a reference, but I don’t agree with that either when you can have sights already available when up.
As for the EoTech window it is even better for running a fixed or flip up sight in the up position. With irons up, myself and pretty much everyone that I know with a lower 1/3 co-witness, looks over their rear irons to see the reticle anyway, which makes irons up no big deal. You actually have to sink your head down into your cheekweld to co-witness with irons which generally is not a natural position if your using a more heads up shooting position.
Edit - Yes I do understand that the Magpul BUS sights flip up quickly and easily but I still run mine up.
I just swapped out fixed irons (LMT fixed front/rear) for folding Troys on my carbine when I installed a T1.
Previously I wanted the assurance of immediate sighting backup because that rifle was running an EOTech that has had dead battery syndrome every once in a while (stopped when I switched to lithium AAs).
I feel there is a good enough reliability and battery life situation with the T1 that the BUIS issue is significantly reduced. The fixed irons also seemed to interfere more with acquiring the dot on the T1 than it did on the EOTech (subjective, just my experience).
On top of that, with a true cowitness, the front sight post occludes my hold-overs.
If target is close and imminent threat, I would not worry about it, eliminate the threat with what I have (T1 used as a big ghost ring), flip up the sights when there is a lul in the action, AFTER I have assessed the immediate area, taken cover, and done a tac reload.
Pat Rogers teaches what jason does. This is how I train. Larry Vickers and Ken Hackathorn teach the sights already deployed/fixed. Using your non firing hand is what I have always been taught and taught others when they choose not to do one of the above.
