    I really haven't kept track, but I'd estimate 15k or more through each barrel. I've done a lot of long, sustained full auto firing which has drastically reduced the service life though. 100 and the occasional 200 round belt dumps were not uncommon.

    I watched some videos of this optic being slammed down on the M249 SAW's top cover during normal belt loading and figured it had to take a beating to get the approved for active service. I compared the TA11MGO with Elcan M145 and it came down to either Trijicon's tritium w/light tube versus having to use a battery to turn on to illuminate the optics. I have two other Trijicon TA31RCO-M150 optics on my Colt M4s with green chevrons, so these probably helped seal purchasing the TA31MGO as I love those optics. Green is supposedly better in daylight than red to the human eye, in which most red is typically cancelled out from the natural blue light from the sun; of course both colors are excellent in low light. I believe the green tritium is expected to last around 13-14 years (red tritium lasts a year or so longer), but if it ever dies, the light tube on the top will still illuminate the center optic. Of course Trijicon will change out the tritium vile for a fee; guess I'll deal with that in about 10 years from now. Right now Optics Planet has a great deal on the TA31MGO for around $1350; that's where I got mine a few years ago during their Thanksgiving Black Friday sale (hint hint).

    Note the two black dots on both sides of the target edges; these really help in aiming as they are set for a standard 16" wide paper target (which is same size for avg upper torso - as shown in pic below). I also love the Tenebraex Killflash ARD and flip up covers that comes standard with these optics.

    And NO, I don't work for Trijicon...

    Have you noticed any distortion at the extreme edges of the reticle? I had a TA-11 on my MM-11 and the crosshairs out on the edges looked a little "warped". Luckily I was able to sell it to someone who didn't care about it.

    Both my TA31 optics have that noted distortion on the right outermost 'leg'; a bit faded, but opposite side is sharp & clear. I believe the owner's manual mentions this is 'normal' but my TA11MGO optic has no distortion whatsoever.

    Besides barrels, what wear items do you guys notice the most on your 23e’s? I’m only 3k rounds into mine and don’t have any spare parts yet except barrels

    Definitely have an extra extractor and extractor pin on hand. I had one break a while back and I lost the pin when I happened. It wouldn't hurt to have an extra complete bolt head.
