Does the "HiRise" block/mount on these Bushnell TRS-25 provides absolute or 1/3 co-witness?

Lower 1/3 on an ar platform. Keep in mind that the regular trs-25 without a mount gives absolute co witness with the medium height mount, and lower 1/3 with a high mount.

The sight will 1/3 co-witness with the irons depending on what sights you are using. I am currently using gen 2 magpul Mbps sights. The emitter in the sight is located at 5 o'clock and partially blocks the front sight so that you can see the FS post and the left blade. Personally I would buy the sight w/o the hi rise block and invest in a better mount. Daniel Defense makes a absolute co-witness riser that runs around $60 on amazon. Good luck

Yes, at least in my M&P; 15-22 with the original sights and with the new MBUS...

It is considered a high mount, providing proper clearance and eye position. If you have a fixed sight and low power setting on your scope, you will be able to see that front sight. You might try a folding front sight to cure that problem. If you are trying to co-witness iron sights and scope, it will not work right, because of magnifying effect, even thou the height will be right.

Co witness is viewing iron sights through the red dot optic. A full co witness will align the dot in the center along with the iron sights. (Aligning all three sights if needed) a lower 1/3 will have the dot in the middle with the iron sights aligned just below the dot. Co witnessing is generally used as a means of using iron sights as a back up to a dot sight, while keeping the dot sight mounted. Either way the dot and iron sights should ALWAYS be sighted in separately. Hope this helped!

I have an F-marked front site base and Magpul flip-up rear. With this setup I have no co-witness. I had to order a mid riser to see through it at all.

Co witness with irons and a red is when the red dot and irons line up. That means if you look through your irons with the red dot on, you'd see the red dot on top of your front post. So whether you aim using the red dot or the irons, your going to hit the same spot. A 1/3 co-witness means the red dot is not on the same line as the irons but is a bit higher on a parallel line. However you are still able to use the irons through the lenses of the red dot. You'd usually see 1/3 cowitness with fixed irons so that you could use the red dot without the irons obstructing your view. absolute cowitness is usually with flip up sights as you can flip down the iron sight when using only the red dot.

I have a flat top with offset front sight, but with the Nikon mounts it should not impede the reticle or center of target but it will show in the site picture.

Depends on the sight that you are using. I am using a Bushnell 3x9x40 I tried it with and without a riser. Without the riser it was clear of the sight. But i am also using a redfeid red dot with laser and found that it will not clear the front sight without a riser. I also have discovered that the Bushnell works very well with the set up. without the riser I can centre my Bushnell scope to the A2 front site for deadly accurate distance shot. It is a good mount for AR platform. I hope this helps.

Have only used the unit on a tripod. Any surveyor tripod will work with I believe a 5/8" thread. Have no experience using with a target detector, so don't know if audible. Sorry.

Depending on the mount you choose, and what iron sights you are using, then yes, it will co-witness...

co-witnessing is based of the height of the dot from the rail, so if your bushnell is a 30mm it should work.

It functions the same as an aimpoint pro, but the comp c3 comes with a lower mount so depending how high you want your optic ( the co-witness concept).

Yes, the block is a separate part. I found the cost of, with or without the high rise block, to be about $5-10 dollars difference from the TRS-25 by itself and bought it. That way I had the option of using the high rise or buy a mid height one (better value for resale). I ended up using a UTG QD mid height mount so I can 100% co-witness on my magpul sites, but thats my preference of site picture.

I have this Bushnell TRS-25 on my AR-15 mounted to a UTG # RS08S3 3 Slot medium profile riser mount. My AR-15 is stock with the A2 front sight. This mount allows co-existing sights to be used in case of battery fail. That way back up sights are a click away.

No elevation adjustment. TMS offers 2 different heights, 42mm and 36mm. I have the 42mm mounted behind a Lucid HD7 (40mm) and it works fine. Should work with any red dot advertised as "lower 1/3 co-witness" 36mm would be needed for absolute co-witness. (35mm)

It is set up at the standard sight height for an AR. What determines the co-witness capability is the mount height you use for your optic. The mount for your optic will determine whether it will be absolute co-witness, lower third co-witness, or completely prevent you from using the iron sights. Do research on the mounts and optics you want to use. But, this sight won't be the reason why it won't co-witness. It is a standard height iron sight.

im not exactly sure since i'm not familiar with your rifle. I have the standard A2 front sight and a rear magpul flip up (probably as you do). I had to switch the highrise to a shorter one (from UTG) to get a better lower 1/3 co-witness. the high rise mount the TRS-25 came with was a little high. good luck

Co-witnessing is the relative vertical linear alignment of your iron sights with your electronic sight. "Absolute cowitness" means that your electronic sight vertical plane will be the same as your iron sight vertical plane. 1/3 upper- or lower-cowitness means that the electronic sight will be offset above or below the vertical sight plane of your iron sights; meaning that you'll see the irons through your electronic optic above or below the reticle. I personally prefer absolute, but many other opinions differ. Hope this helps.
