| When it comes to mounting it on a carbine I see a lot of rifles with half the optic on the upper and the other half on the hand guard. Can some one explain this to me? I know that having the optic mounted farther down the rifle is better as far as speed and target acquisition goes, is that all? |

If you aren't going to mount a magnifier is this still a wise place to mount it or should you move it back a little? The further back the optic, the greater the FOV through the optic which makes finding the reticle faster/easier when shooting from awkward positions w/sloppy cheekweld. Tomac |
| no particular need to move it backwards any.why would you want/need to? i personally like mine being out in front of me a little ways,it gives you a better ability to use your periphial vision to track/engage your target. as long as your eotech is'nt touching the handguard your gtg.which model do you have? the 516,517,557 all have a built in riser/base that is specifically for the ability to be up over your hg. |

dont compute there, tomac!?..... so the more backwards you go, it helps your fov and cheeckweld? wtf?  i hope you was meaning forward "with the optic"........Take your Aimpoint/Eotech/whatever. Hold it at arms-length, look through it and locate the reticle. Move your head slightly to either side, notice how much movement is needed to lose the reticle. Bring the optic to only a few inches away and repeat. You'll discover that having the optic closer to your eye gives you a wider FOV through the optic where the reticle is still visible. This means an optic closer to your eye is more forgiving of sloppy cheekweld than the same optic further out, making the reticle faster to locate & use. Tomac |
| Interesting topic. I would tend to agree with Tomac. Most of us typically just put the optic in a certain place and leave it there. Very few of us actually train with the optic in multiple positions. I have my 553 mounted on my upper and overhanging on my HG a little. Tomac's point is well taken especially when I have to where a gas mask on an entry. Your entire FOV changes when wearing a mask and getting anything remotely close to a usable cheek weld, while wearing my mask, seems nearly impossible! There have been times that I have had to actually hold my rifle or subgun out in front of me to be able to even pick up the reticle at all! The placement, IMHO, does effect your FOV! Also keep in mind that what works for one does not necessarily work for another. Use your gear, mix things up a bit, and practice shooting not only from a standing, static position but from several positions (prone, on your back, on your side, etc..). Of course if you aren't LE or MIL please do these in the presence of a trained firearms instructor! |

Policetacteam has it right. Last summer during my carbine classes I learned the hard way how difficult it can be to quickly acquire/use the reticle when shooting from awkward positions (on your back, urban prone, rollover support-side prone, etc) and have come to appreciate having the widest FOV possible through the optic (YMMV). I also found the Eotech's outer circle to be invaluable as an aiming point close-in when POI doesn't yet coincide w/POA and/or as a bore reference point when shooting from unconventional positions.

Ive got the 512 in the mail coming to me. Why wouldn't you want it attached to your handguard? Mine is free floating and gives me one uninterrupted rail. so I could have mine running in between the two Outside of the discussion on forward or back for FOV, your 512 will look like it's more forward than it is. The long battery compartment is not part of the mount. In other words, with the 512 mounted at the end of your upper the battery compartment will over hang the hand guard quite a bit, but it's not actually attached to it. Bridging the gap between the upper and the rails is often seen as bad, but I think this can be discounted a little with a solid, free float hand guard and a red dot versus a scoped rifle. Could be wrong, I don't bridge the gap anyway because my optics are mounted rearward or have a mount that only attaches to the upper. |
| i'm understanding whats being said but,...... i think personally that it sounds as though some are thinking in terms of a powered scope; in that the best way to benefit from it's advantages is in getting it close to your eye. the advantages of the aimpoint/eotech red-dot is not anything like this in terms of magification. hence,my end of receiver mounting. the value of the eotech is in that your eye is drawn to the donut and your peripheal vision is able to pick up side movement.i thought that was the whole idea behind the red-dot. i'm not saying mount it over your handguards,....just far enough away so that your peripheal vision is also utilized. just my opinion guys,you go w/ what feels natural to you.good discussion though,thanks. |
