| I have the primary arms red dot in 3MOA.... if I put their 3X Magnifier behind it, will it make the dot larger? i.e. turn it into a 4 or 5 etc. MOA dot? |

I am assuming that the Primary Arms work the same as the Aimpoint / EOTech 3x's .... it will not make the dot larger but the relative moa will change on you in relation to whatever power magnifier you have (3x, 4x, ect). moa is relative to distance ~1" at 100yards is ~1moa
.................... inches * 100........................ MOA = –––––––––––––––––––––––––– ............1.047 * distance in yards........... so...if you are shooting at a target 100yrds away you and have a 2moa dot, the dot will cover right at 2.1 inches. However, if you have the magnifer on, the target will appear 3x closer (~33.3yards) so 2moa at 33.3yards should cover only 0.7 inches. but...this isn't how it works. The dot will cover the same amount of space at 100 yards with and without the magnifier so with the 3x the 100 yard target appears 33.3 yards away but the dot still covers 2.1 inches on the target so a 2moa dot will appear to be ~6moa. So yea it triples the size of the dot and the size of the target...the dot will cover no more and no less of the target with the magnifier than it would without the magnifier. ***Sorry I was doing the math as I went and honestly did not know how it was going to turn out so i probably rambled but to answer you question, yes the dot will go from 2moa to 6moa (or 4moa to 8moa) but it will not cover any more of the target than the dot would without the magnifier...the 3x magnifiers are designed to help you see the target better, it only help a little when it comes to accuracy*** |

VIDEO What could he be doing wrong? |
| If you're talking about his poor groups, it looks like he's changing the resting position from time to time, he's not getting into his natural point of aim, and a couple of other things. I didn't have the sound up, but if he said the dot got bigger, it does, but it also makes the target bigger, so the dot covers the same amount of the target regardless. |

It made the dot larger and made it harder for him to see the target. |

It will also make the target appear 3X larger. If you sight on a 6" target at 100yd with a 3moa dot the dot will cover 1/2 the target. If you use a 3X magnifier you now have a view that looks like a 1X 9moa dot on a 18" target at 100yds. The sight picture on the 100 yrd view with the magnifier is the equivalent of standing 33.3yrd from the original Un-magnified target ( 3moa dot on a 6" target).
Your equivilent view is equal to the zoom x target size at the same distance, or the distance/zoom and keep the same target size. Hope that makes sense. |

VIDEO What could he be doing wrong? I mean...he is just not thinking about it. You see the target like it is 3x closer than it is so he is probably thinking in terms of target size vs dot size and not even considering distance. He probably is gauging the dot size on target w/ the 3x magnifier @ 50yards against the dot size on target w/ out the magnifier at ~15 yards. He wasn't doing anything wrong...he was just thinking about it wrong. |
