Rad!!!
I’ve done -19 (I think) to around 90 but to see it function at that temp for that time is something cops in cold places want to see. Keep that stuff coming!!!

I was shooting some 3 yd Eleanore drill's yesterday,
1/2 way through the 2nd mag my hit's were low,
thinking it was just me screwing up on hold over, I
took some shots at a 25 yd plate and shot under,
I checked and all witness marks were on the money
so I moved up to 15 yd's and all were low.
I went back and shot paper at 7 yds to find poi was
4.5" low.
It just so happens, I'd received a call a couple hrs earlier,
a 507K I'd ordered with a lgs 10 days ago is in.
This one has 3500 +/- rds and is my second Holosun
Holosun in 6 or so months to take a dump, the first was
a 407C VII that lost zero in the first few hundred rds.
I know their customer service is very good and it'll be
promptly taken care of but, it doesn't instill a lot of
confidence for daily carry.
The 407C was on a Primary Machine direct mill M&P 2.0C, optic sent in
with slide and installed by PM, POI went 5" high and a couple " right.
The 407K is on a 365XL installed by myself, proper torque, blue Loc Tite,
both optic's had paint witness marks on the mounting and adjustment screws,
none of which had moved.
Both sights had some adjustment after loosing zero, although not nearly enough
to compensate for the loss, not that I would consider that optic for carry or run
an optic at the very outside of adjustment for other than fun.
In 11 years and well in excess of 100,000 rds of shooting slide mounted red dots, I have never had one lose zero. HOWEVER, at a recent Dave Spaulding class I attended he said he has seen it happen and had it happen to him. Furthermore he says that is his biggest hang up with the MRDS.
As another current thread reminds us, iron sights also occasionally lose zero. A serious red dot shooter should own a Wheeler laser bore sighted, or equivalent. We use ours almost daily, between mounting and check optics. The Wheeler gets us within an inch or two at 25 yards, and quickly shows if a zero has gone awry.
Likes pretty much everything in every caliber.
