The Pyser-SGI Small Arms Collimator (SAC) series represents one of the most crucial battlefield optical implements available today. The Small Arms Collimator is a precision optical device that allows shooters to confirm zero/ or re-zero weapons in the field, to a high level of accuracy, without live fire. Confirming zero or re-zeroing a weapon is very important in the field. Weapon sights and optics can shift zero from many different factors including airborne insertions, falls, explosions, etc. But, the SAC can also be extremely useful when changing optics, in our case: swapping a day scope for a night vision scope in the field.
Until now, laser boresight devices have been the default means of confirming or re-zeroing weapons without firing a shot. The problem with this is that laser boresighting equipment is inherently inaccurate, causing an M4 to be off by as much as 8 MOA. On the contrary, the SAC is one of the most accurate devices of its kind (accurate to 0.25 mil, 1 MOA). Manufactured in countless variants, the SAC works with irons sights, optical sights, day scopes, and night vision scopes. They are available for rifles, carbines, submachine guns, machine guns, sniper systems, and grenade launchers. Additionally, laser SAC’s are available for use with laser aiming devices.
The Small Arms Collimator has been in use by the British military for over a decade with fantastic results. They are so good that they have caught the eye of many units within the US Special Operations Community and other allied nations. The SAC is easy to use with very little training and does not require a “master weapon.” It does not emit light or any other signature, nor does it require a down range target. A single SAC can be used on any “like” weapon system.
The Pyser Small Arms Collimator is one of the “must have” pieces of kit for any combat unit. The ability to quickly and accurately check a zero or re-zero a weapon without firing a shot is paramount to mission success in non-permissive environments. We are talking about operator safety here. Weapons and their optics can lose their zeros due to anything from a rough insertion to normal battlefield abuse. Without the ability to achieve accurate hits, a Warfighter’s combat effectiveness is substantially reduced. The SAC is the most accurate and proven method of confirming and re-zeroing a weapon. No unit or team should deploy without them for all their weapon systems.
The SAC is extremely rugged and requires no batteries. We especially like this system for its use in swapping a day scope for night vision scope. No longer does a separate night vision-equipped rifle need to be brought into the field. A lot is mentioned about “must have” kit. Well, this is actually one of those must-have items.

I don’t see WHAT it is though… just an optical boresighter?
Looks great!
Definitely a must have for your high-risk kit bag
You plug the pointy end into the barrel and make sure it is aligned correctly.
You look through your optic, in my example it was an ELCAN C79.
You then adjust your sight to the middle of the target.
You now have a rough zero, that will get you on paper.
Take it out, continue to zero your rifle so the rifle and your eyes are hitting where it should.
Plug in the collimator again, make sure it’s aligned again.
Now you might see that it isn’t pointing dead center anymore. So you mark down the grid numbers. Keep that safe.
Now you can at anytime, check your zero just by plugging the collimator back in. Something to be done during battle prep. If your rifle gets beaten up somehow, it’s quick and easy to verify if your sight is still zeroed or not. If it isn’t. Just adjust your sight back into the grid numbers you have noted down when you originally zeroed your rifle.
Hope this explains it, we had/have them in Denmark too when I was still active.
Nicely said!
I would like to add that optics mounts and their positions will play a role in the “accuracy” of the zero you obtain. It’s important to put the optic in the same place on the rail everytime as well as use good quality mounts when you have the option. With the quality of some of the mounts we have today, zero should be damn close in the same rail position.
Well, I was going to give an explanation, but Keld seems to have nailed it.
Thanks for that comment Clasky.
I would like to say that we did experience some problems. In the beginning people thought they could just plug in any collimator(We had several in each unit) and then adjust them back, but that didn’t turn out so. Make sure you rezero with the exact collimator that you originally used. Write down its serial number.
So to clarify – ideally you would need one for each weapon?
No world is ideal….
We had one per platoon and that worked out fine.
Understood, tango.
He was more so stating that you need to use the same serial numbered unit that you recorded your data with. We do something similair with the howitzers but its with the sight and the barrel. You could have ten weapons and use the same bore sight in them problems come when you use a different bore sight other then the one you sighted it in with. This is due to slight variances in tolerances etc.
Pretty cool but they don’t list a price on their website, anyone know how much they are?
Too bad it’s restricted to government sales only. Hopefully that will change in time.
