1911 2011 Bul Armory handguns range visit SAS II Ultralight

SAS II UL Optics Adjustment Issues – The Wedge Was Not Needed!

My range notes for today’s range visit:

This is the first time I’ve tried a range other than Elite. Elite closed last weekend, so today I visited XCal in Ashburn (30 min drive – 30 miles).

Shot 48 rounds of Norma 115-grain FMJ. There were no fails.

I also shot 64 rounds of Fiocchi 115-gr FMJ. There were no fails.

Total rounds this session was 112 rounds of FMJ. There were no fails.

I spent a majority of the 1-hour session adjusting my new optic (Holosun HS507K-X2 ACSS). It was initially frustrating because I couldn’t hit point of aim at all. I kept adjusting the sight and was able to get proper windage but couldn’t get the proper elevation…no matter how much I tried, I couldn’t get the dot lower than 6-8″ above the bulls-eys when shooting at 10 yards.

I finally stopped and decided to remove the optic wedge I’d installed (was supposed to fix an issue with the SAS II UL having elevation issues when an optic is mounted). Once I removed the wedge, I reinstalled the optic and was immediately hitting the bulls-eye. It still needs to be fine-tuned, but I’m quite happy with the functionality of the optic and that I solved the elevation issue!

I bought a crapload of ammo, but only got to shoot 112 rounds, since I was attempting to adjust the optic’s point of aim and since I had the issue with elevation.

I wish I’d shot a bit more to break the 500 round count.

I’ll attempt to visit again next week. I’m probably going to apply for membership before then.

I almost decided to put the irons back on tonight, at the range. The only thing that stopped me was that I’d forgotten to bring the irons with me. That forced me to bird-dog the issue – I didn’t need that optic wedge I’d installed and I shouldn’t have immediately installed it. That’s what I get for believing an internet source – bottom line is, don’t believe everything you read on the internet! Trust but verify. If I’d have installed just the optic and not the optic wedge, I’d have not had an issue at all.

Bul Armory Optic Reflex Sight SAS II Ultralight

Holosun HS507K-X2 ACSS Vulcan Mounted to the SAS II UL!

This optic is a lot smaller than I thought it woudl be, but it’s also made for smaller handguns (which is why it’s denoted as 507K).

It was rather easy to remove the “iron” rear sight. In fact, the rear sight was loose and was rattling around! It was probably due to the stout JHP I’ve been recently shooting.

I bought an optic shim (I also bought an extra one, for redundancy purposes), as the 507K has zeroing adjustability issues with the SAS II UL.

I cleaned out the optics screw holes and then used the screws that came with the optic to secure the optic to the slide (used blue thread locker).

The optic works well! I have it set to use the ACSS reticle, have the lighting dimmed a bit, and have the setting locked in place. I also have the Shake Awake feature enabled.

I’ll have some time to shoot it tomorrow (will try to visit a new range, as well).
