    Forward Mounting a Red Dot on an M4orgery

    Does anyone have any experience or first hand knowledge of mounting a red dot forward? On or really close to the gas block.

    If so, what is your opinion and practical experience?

    don't do it. red dot sights should be on the receiver. the reason is the farther forward the red dot is the more it will move as you breath and or move just like the front sight.

    Surely, wherever the red-dot thingummajig is affixed (provided it is aligned properly) the direction of the red dot itself will move exactly with the direction of the gun : so it doesn't matter where you clagg it.

    What do you mean by "red dot" ?

    If you're meaning something like an Aimpoint or other similar device, you'll find mounted at that distance from your face, you won't achieve the "eye relief" required to set the dot on the target.

    If you're meaning some form of reflex sight which projects an emitted light onto a small glass or plexi plate then though you won't suffer the eye relief issue however I'm at a loss to understand why you'd want to mount it near the gas block. Remembering that it wasn't manufactured to be specifically mounted there, you might have issues with zeroing (I'm speculating on that because I've never tried what you're suggesting)

    Stick with mounting it correctly on the receiver.

    If you mount it forward of the receiver make sure that you have a free float fore-end.

    I know that some 3-gun types mount a scope on the receiver and an RDS at 2-3 o'clock on the fore-end. Is that what you are considering?

    The target distanceexpectation is less than 75 feet, most likely under 50 feet. The mounting it forward is meant to allow a wider field of vision using both eyes. Wasn't sure if it fell under the "it seemed like a good idea at the time" category for the m4orgery.

    It is a 40 mm aperture tube type and no eye relief problems were experienced with temporary mounting. Unfortunately, it is too long to fully/securely mount on the gas block and test.

    t: Just the rds forward at 12. Do you have one to do a quick test with? Clear a house?

    take a long stick and tape a paper ball towards the end of it. you will notice while holding it it wobbles all over the place and you have to really concentrate to get it to stay were you want it especially if your moving around. if you move it towards the middle it will move around less. the result is your not chasing your red dot.

    I agree in theory, but it's no worse than your front sight post.

    Why do you want to put it way up there?
