Primary Arms 3X LER Red Dot Magnifier Gen IV

Massive upgrade over the Gen 3.
<br>
<br>Side by side comparison the Gen 4 is just better in every way. Glass is clearer than the Gen 3 and MUCH less fisheye distortion. The design of the magnifier also makes it easier to mount behind a dot on limited rail space (no flared from objective that sticks out from in front of a mount).
<br>Don't listen to the ignorant reviewer that says the Gen 3 is better because he doesn't like the rubberized coating on the Gen 4. Fact that coating helps with durability. And handling the two side by side you can tell that the Gen 4 is better built.
<br>Having now used both the Gen 4 is well worth the upgrade.

It's Light Years ahead! I had a Gen III that I had little interest in for several reasons that I will not get into here. The Gen IV reset everything. The optic is now behind the mount and allows your red Dot to stay to the rear. The sight picture is brighter and more clear. The body is rubber armored but is a little wide and won't work with a flip sight that doesn't have a decent offset of the axis. I think the PA QD flip sight is a bit bulky but it works well where other won't clear the BUIS and/or charging handle and it offers lockdowns at 45 and 90 degrees. Please excuse previous negative comments and understand that this is a great piece of equipment.

Well built 3x magnifier at a bargain price! Put this on one of my AR's behind a PA/Holosun HG503g-ACSS and I'm quite impressed with the edge-to-edge clarity and brightness. A couple of X-Y turns to center the reticle and a twist of the focus ring to present a razor sharp image with a decent eye relief. Mounted on a flip-over, it's out of the way or back in play in just a couple of seconds. Bundle this with top-shelf customer service and lightning fast shipping andit's a no brainer!

This is my first experience with a magnifier with a red dot. All I can say is I am super happy with the magnifier. Very clear, sharp, and crisp image. Works perfect with my Sig Romeo 4C on my AR Pistol. I can hit steel plates at 200 yards. Another great product from Primary Arms. Shipping was super fast too!

Works perfectly with the American Defense swing to side magnifier. Glass is clear.

HS503G sight is on a .300 BO pistol. I did add the following :
<br>--Primary Arms Advanced 3X Long Eye Relief Magnifier, Black PA3XLER-AD. It is functional as close as 15ft. 100yds is unbelievably clear! I'm not a great shot, but my normal group with this is at 50yd- 1/2", and 100yd- 1.5".
<br>--Primary Arms Quick Detachable Flip To Side Mounts - Standard Height, Black PAQDMQF-01. This is NOT "slap to the side" mount, but I don't need that. It is "move to the side" and that works for me.

I attached this with: 'American Defense Magnifier Swing Off Mount - Lower 1/3rd Co-witness' - Works beautifully with my Holosun HS503C! Lines up perfect!

I bought this magnifier along with the QD flip mount and I love it!!! The view is clear as crystal! And the mount is solid as a rock. The best part is that it lines up perfectly with my Aimpoint PRO! I'd totally recommend this to anyone I know.

Very impressed with this magnifier! Very good eye relief. This is the first magnifier I have used so I don't have a lot to compare it too but for the price I don't think you can beat it. I am sure it's not the quality of an Eotech or Aimpoint but its also not the price of an Eotech or Aimpoint. Unless you are getting deployed I would strongly recommend looking at this before dropping $400 on a magnifier.

I have two of these current and previous Gen. Both work like champs! I don't see well in the distance so 25 yards without magnification would always be a problem. Not anymore. Good Stuff

I am building an AR-15 for my son. I bundled this 3x LER Magnifier and swing mount and chose overnight shipping and got it the very next day. I installed it and everything went together perfectly. I put the rifle to my shoulder and after a few very easy and minor adjustments the sight picture behind an Eotech 517 was brilliant crisp and very clear. Absolutely no smudging of the center dot inside the reticle. Compared to my Eotech G33 magnifier on my Daniel Defense the sight picture is so close to being the same! Sure it's a bit larger in size than an Eotech but not by much. The body is very rugged and the glass DOES collect as much light even on the overcast day that we are having today. Honestly If I had known then what I know now.....I would own 2 of these things and saved over $400!!! Way to go Primary Arms! Nice piece of hardware for such a low price!!! Get one and pat yourself on the back for the $$ you just saved!

Running it with my PA advanced micro. Both with American Defense absolute QD mounts. Great quality use it on my patrol rifle

Works great behind my EoTech 512 and I'm very happy with it. Can't go wrong for the price. The glass is very clear and bright. I would highly recommend this to anyone on a budget and not looking to spend the big bucks on a more expensive magnifier. This one will do the job just as well and save you big $$

Works like described. The standard height PA flip to side mount works perfectly with my EOTech holographic sight. Would recommend to the old men I see at the range every time I'm there.

Perfect magnifier at the perfect price. offers good eye relief and is crystal clear. i would highly recommend this!

I have owned both the Eotech G33 and Vortex VMX-3T and much prefer this magnifier. The eye relief is excellent and allows me to keep my normal cheek weld when I move the magnifier into position (I had to move my eye forward for both the Eotech and Vortex). The optics are crystal clear, and it works extremely well with my Aimpoint T-1 and my Primary Arms MD-ADS. One very minor nit is that the caps need to be removed and a tool used to re-center the red dot when moving the magnifier from rifle to rifle. It is really just a personal preference thing to have the dot centered (PoA and PoI don't change when adjusted), and I would like to be able to do a quick finger adjustment when I hot swap the magnifier. I highly recommend this magnifier! I would also recommend the AD swing mount to go with it. I have the absolute co-witness version, and the magnifier does indeed clear my Magpul MBUS when I swing it out on all three of my rifles on which this magnifier has been mounted.

Super fast shipping as always with Primary Arms. The product is very solid feeling and has great optics. The eye relief on this model is on par with the $500 magnifiers. I just couldn't justify spending close to what my AR cost on a magnifier. This fit the bill and then some. You wont me sorry. Please note that with any optic you AR will gain a bit of weight.

The magnifier lined up perfectly with the Bushnell TRS-25 on my AR-15. Purchased along with the PA flip to side mount. Quality product. The long eye relief is as advertised at about 3.5 inches. Focused easily. Made zeroing in at 100 yards quick and painless. Great customer service. I'll be a lifelong customer if they keep releasing products like this.

I've been waiting months for this to get into stock and was about to say F'it BUT glad I didn't!!!!! eye relief is perfect and a steal at $99!!!!! PA QD mount is awesome also! The service is always good.

So, I now own both Gen III and IV. I was waiting for Gen IV for months. I actually broke down and bought a UTG unit a few weeks ago, but returned it a few days before Gen IV went on sale. I wanted Gen IV that bad...Well, gen IV unit is slightly lighter (good) than Gen III, but the "rubberized" cover on Gen IV plain sucks. It looks cheap. Compared it my my Gen III... no comparison. Gen III looks "pro" made, Gen IV looks like a Chinese knock-off but with a good eye relief. I also bought a PA QD flip-to-side mount. Same as my Gen III setup. The new mount has noticeable play in it. The old one is solid like a rock. So overall, I put my Gen III setup back on my 9mm AR15 right behind the TRS-25 and put the Gen IV into the "parts" drawer. When I get another red dot I will take the IV out. Overall, I would have not bought it if I could "touch-n-feel" it first. I am sure it's a good product and will work for anyone without the Gen III (if u have it - keep it!)

I was on the fence on getting the aimpoint magnifier but i couldn't see my self shelling out that much cash for 3x zoom. So when i saw PA was making a gen IV of theirs, i scooped it up...looks great on the rifle and the turrets to focus the red dot to the center is nice. Cant wait to get to the range.
