Anyone ever damage an acog? My buddy dropped it about 6 feet, landed on steel, had the neoprene sleeve on it and miraculously does not even scratch the optic. Haven't checked zero yet. It was not on the rifle.

I'm pretty sure those poor acogs in .mil hands have seen worse hits/crash/etc.

Anyway if the lens arte not cracked shoot it and report back

Yes, normally with Mil it'll be either over adjusted elevation/Windage knobs or some idiot will scratch the lense/distort the lense by putting CLP on it so badly that you can't see out of it.  Also IEDs but that's another story.

During my most recent vacation in Afghanistan I saw M4s with ACOGs dropped from small cliffs or fall out the back of an Osprey taking off and even ones that survived IED blasts and even when the M4 is destroyed, the ACOG was still in tact.  I have even seen the glass cracked (target-facing front-most lens) and it was still keeping zero.  Ill expect the M4 to fail 100 times before the ACOG fails.  I think the only thing that would make an ACOG unusable is either a direct bullet strike or repeated direct strikes with something like a sledge hammer or explosives going off right next to it.  And no I don't work for Trijicon, I am a Marine.   I was so impressed by how durable the ACOG is that I bought one for my primary AR.  

If you want to test your zero, re-zero, then move the reticule by a known quantity (say 5" to the right and 5" up) and verify the zero moved the correct amount.  If not, then the adjusting mechanism is likely damaged.

I have heard of the over-adjusting the knobs but I think you would have to put considerable torque on the adjustment mechanism to actually break them.  We go to both ends of the adjustment range to count clicks since 1 rifle is often used by multiple Marines.  I have never heard of CLP damaging glass.  Can you elaborate?

It fell 6' while protected and not on a weapon?  I wouldn't think twice about it, not an issue at all.  I've seen broken ACOGs before, but nothing from that minimal type of event.

It was more of a question than a worry. I was just amazed that it didn't even ding the aluminum or even leave a mark and it was more like closer to 7 feet dropped on steel.

Yeah it had the neoprene on it but it did hit pretty hard, more like 7' into steel. I am not so much worried as I am impressed at how it didn't ding or scratch. I would assume it is ok. I talked to a trijicon rep and he said he would have no problem chucking a ta33 off of the roof of the building onto asphalt.

Haha, agreed, I treat my stuff like tools but then again I don't throw them off of roofs either. From what he told me they don't publish a lot of their testing but said the R&D destructive testing gets pretty creative and said the Millspec testing requirements were pretty much minuscule in conparrison. the TA33 was dropped 20' to concrete, scuffed and scratched, still held zero. Pretty good talk with the rep actually.

I had one that wouldn't zero because the prism came loose from its mount, but that was a factory defect and not from damage.

Seen one break while on a pre-deployment workup in 29, fell out of a 7 ton (alot further than 6ft) and landed on cement... when you looked through it there was a dark purple blob on the top half

I was issuing one out the other day from the rifle magazine and the numbskull dropped it about 4.5 feet onto concrete, no damage.

I carried a TA31 as a designated marksman for my Infantry squad. That thing was a tank. Loved it so much I bought one for my primary AR. That has also been flawless although it's treated much more kindly.

I did however drop a brand new TA33 from 4-5 feet (not mounted on a rifle) and it landed at a weird angle and cracked the eyepiece lens Trijicon being who they are though fixed it without an issue. Basically no questions asked.

I will keep buying Trijicon optics. After I get my next couple MRO's, I'll be about evenly split between Trijicon and Aimpoint, with a smattering of Leupold for good measure.

This +1

ACOGs are ridiculously tough. I read a battlefield report of an ACOG losing chunks of material from a direct bullet impact mid-firefight and still functioning without loss of zero.
