I have a 556 with the side buttons on a flat top. Just wondering if it makes a difference were it is mounted. I have it as far back as I can with a troy flip up sight. I see people mount them everywhere. I see them as far forward some times with nothing behind it to block the buttons. I know you should not mount it on the front hand guard as there is a little play there. were I have it now is a nice balance on the rifle. the farther forward the bigger the receptacle is tho.

I prefer mine as far back as possible to maximize FOV through the optic (this makes it more forgiving of imperfect cheekweld like when shooting from awkward positions). Reticle doesn't get larger the further forward you mount the optic, it's an optical illusion.

I have had the exact opposite taught to me. The closer the optic is to you, the bigger the optic appears in your FOV so therefore, by placing the optic further forward, you will have a better view of the "battlespace." The actual FOV THROUGH THE OPTIC should not matter if you shoot using both eyes like you are supposed to. I put mine in the middle simply because that all of my friends that used EOTechs in Iraq/Afghanistan told me that is where they are supposed to be placed. I also so a tactical carbine vid that said the same thing. Maybe you can check out some pics of where the magpul guys are someone puts their non-magnified optic... they use aimpoints but it is the same exact principle

Hmmm...the reticle size doesn't change based upon its distance from your eye but it does take up more or less space in the optic's FOV.

I subscribe to this methodology. I also consider the balance of the rifle which means I end up mounting it as close to the rifle's center point as possible which is usually above the magwell.

Reticle doesn't get larger the further forward you mount the optic, it's an optical illusion. Tomac Would an optical illusion that affects an optical sight be relevant? I mount mine more based on balance than - the reticule appears larger the further out you move it, but the difference in receiver space is pretty negligible, it's not like your mounting it on the trunion of a .50 cal, and the reticule's way out there. Otherwise, RDS placement is more an issue of accessory mounting and integration, and personal preference. There's no "right" place to put it. ~Augee |

Usually right above the magwell is what works for me. I wish I could figure out where these myths come from about having a better view with it further forward.. seems to pop up every few months, get argued out, and then proven wrong. |

I've got a 512 that has rear buttons. That means I need to move it forward a bit from the BUIS.
Basically puts it over the mag well so I just move it as far forward as I can. (Magpul HG and no top rail) Logically, I think of it this way. Many guns have rails are only on the upper. That means you have limited space to put them. Those guns with HG's with rails also have TONS of other crap mounted out there.(flashlight, VFG, laser, blah, blah, blah...) Weight begins to be a problem so they even mount them back on the upper to spread it out. If you are limited to the upper rail, its limited space. We're talking +- 2 inches typically of actual movement on center. Does it really make much difference? Probably not for +-2 inches. Go with what you like and what works for YOU. |
