How far is a click?
How far is a click?
(OP)
I need to develop a mount for an ACOG Scope that has an adjustment of 3 clicks per inch at 100 yds. So how far is a click is terms of units that I can relate to my mount? Basically, I need to know if the mount I'm developing can be level or if I need to design in an angle in order for the projectile's trajectory to match the existing peep sights.
I'm asking here because I could easily ask a coworker and look stupid since I don't know something that is common sense in this industry, or I could ask here and look smart.

RE: How far is a click?
You can obviously make "a click" any dimension you want depending on the pitch of the thread and the distance between the detent locations.

my $35 simmon 22 scope is 1/4MOA per click.

What type of mount is the scope for? Weapon?
RE: How far is a click?
My understanding is that the scopes are always designed to be level.
To some degree, this makes sense, since otherwise, you'd wind up designing for a particular weapon, since each weapon would have a relatively unique distance from sight to mount.

Again it goes back to if it is a specific weapons mount or if it is a general rail mount. If it is a mount, say for an AR-15 handle mount, the top rail should be level while the bottom is going to be tapered. The handle angles downwards. If it is a rail mount for a flat top it will probably be level. The scope should be able to adjust to compensate for elevation - there may be an adjustment on the front for that purpose. (I may be thinking of another combat scope so that could be incorrect, although the reticle elevation adjustment should compensate)
Some scopes do angle downwards depending, again on the setup. You shoot upwards to have the bullet fall on a specific zero at a designated distance. I do not know if that applies to the ACOG.
You may just want to get clarification from someone there to be sure... Sometimes its better to look "stupid" then end up being "stupid". (Although its a hard lump to swallow sometimes, you should have the internal resources to ensure accuracy no matter how "simple" a problem seems to be.)
RE: How far is a click?
The history behind the question is because we have several mounts (Picatinney rails) added to our weapon system to fit customer desired optics such as the ACOG and a AN/PEQ-2. Since our projectile doesn't follow a straight-line trajectory like the laser on the PEQ, we had to create the rail with a taper that matched the trajectory at a specific distance. It is up to the gunner to compensate the laser spot with the actual trajectory at any other distance.
Considering that the ACOG also gives a straight-line target through the retical, it will also have to be sighted in at a specific distance. Of course, this may all be a mute point because we learned from the customer that the gunners have the ACOGs for another unit. In the field, they will quickly take the ACOG off that, place it on ours, fire, and put it back on the other system. No time to sight the ACOG in to our system so it is up to the gunner to mentally make any corrections.

RE: How far is a click?
Sounds like an interesting field. I have been trying to brainstorm ideas on the rail systems (One of my ideas was already in use - figures) but I do not have the interaction with the industry. Been toying with it some on my free time just for something to do.
Anyway, hope your system works out.
