New to the forum, and certainly new to red dots, 1-4X's etc.
I'm looking for my first optic to sit atop my first AR build in 300 BLK. I'm liking the idea of some magnification for working from 100-200 yards but at this time not at all interested in BDC type reticles. I'm also liking the idea of a red dot. I have a budget of about $400.00 at this time, limited but a budget is a budget.
In that range I like the Leatherwood Hi Lux CMR, the Mueller 1-4X24 Speed Shot and the Millet DMS-1, so far. There are other RDS's I like but they include no magnification.
My question: I'll use the Mueller for this, it has a 4 moa dot, I'm assuming that's at 1x. When the magnification goes to 4x at 100 yards the dot has to remain the same size correct? in other words at 4X / 100 yards would the dot decrease to 1 moa staying the same size? Obviously the dot can't magnify 4x or it would cover 16" at 4x / 100 yards. Am I thinking about this correctly?
I warned you it was newb dangerous...

I am not sure if those scopes are first focal plane or second focal plane reticles. If they are first, the reticles will remain a constant 4moa through out the mag scale. If they are second focal plane, most scope manufactures set the reticles to the top end of the scale, so it would be a 4moa dot at 4x. And now the tricky part, as you turn down the mag, the reticles actually increases in size in relation to the target. This means the reticle would actually be 16moa at 1x.
I guess if they did set the reticles size at 1x, on a second focal plane scope, at 4x it would only cover 1moa.

I have the Leatherwood Hi-Lux CMR 1-4x scope and consider it an excellent budget scope.  It is a second focal plane scope so the reticle size is constant through the magnification range.  It is  also available with upgraded lenses but I have read while the difference is visible it does not negate the original which is about $150 less expensive and still available.  SWFA usually has a package price with an S. S.A.L.T. AR mount for around $330.  I initially tested in for durability on a Marlin .45-70.  It is currently in a Burris Q R P.E.R.P. mount ($20 rebate through 12/31) and used on various ARs.  I have no experience with the Mueller counterpart.  The CMR is Chinese from a factory supposedly owned by Leatherwood and the quality control seems to be good.  Illumination is not visible in broad daylight but works well in low light.
