Reviews & Ratings for IMG AR-10 .308 12 Gauge 19in Complete Upper Receiver w/Two 5 Round Magazine — 15 reviews — Page 1

Has issues with ejecting, magazine staying in when shooting magnum, and the magazine springs are really poor quality so there is a lot of failure to feed issues I'd say you loaded the magazines the day prior. Had to fix that myself with quality wire springs I made myself. Had to also replace the buffer spring on my lower (which was already set up for the RAS -12) with a stronger one to stop getting the failure to eject. Also I'm not a fan of the chokes it comes with not being labeled.

This is ignoring is proprietary magazine that are very overpriced.

Also while trying to fix some of these issues I stumbled on a video where it misfired because the spring holding the pin back is not strong enough so when the bolt released forward it fired.

Lots of these issues can be resolved by simply using better quality springs.

I was not expecting a gen 12 I was expecting something that worked. Seems like I'm not the only one with issues if you look this thing up.

First off. I love how it comes in a plain box. That's fantastic. Keeps peoples noses out of my business.
One word " Complete" I was happy to see it even had a muzzle break as well as just a thread cover.
Both mages are sturdy and love that it comes with chokes. and flip sights.
Its a bit tight going on to the upper but fits well once its seated. Great value overall.
Once I get to the range I can give a up to date review.

Took me a long time to get this together because it wouldn’t fit on two different lowers. I had sanded the rear of the upper receiver until it mated. Probably took off .15 of material before it would go together. Mine doesn’t like high brass but it shoots and cycles low brass as it should. I feel like I spent way too much on this shotgun but oh well. There is much better out there but this one is mine. Also, the magazines need a little tweaking before they work properly.

The Anderson AM10 DPMS Gen 1 lower, which happens to be the one its shown with in one of the pictures in the Optics Planet ADD is a perfect fit . So I finally got the correct one . AT3 Tactical have the AM10 gen1 lowers on clearance for 115 as of 8/1/2025.ANYONE thinking of buying this AR12 LOWER , don`t unless you know your way around the AR Platform , or are willing to learn on the fly , you will need to make adjustments , you will need to tinker with buffers and springs and the adjustable gas system to get this working properly . Thats about it GOOD LUCK AND HAPPY SHOOTING .

The Panther AR .308 lower was off by a hair , just enough that I`d either have to drill the rear takedown pin maybe 2/100s of an inch to get it in , so before doing this I ordered a Anderson AM10 DPMS GEN1 , will have to see if its the match I`m looking for , if not then a little alteration may be in order . I`ll write another after .

I was very happy to find out the 12 gauge upper sold via IMG is actually made by Panzer Arms .
I bought the M4 and AR12 Pro BOTH ARE NICE , the M4 is a great shotgun , I`m feeling a good vibe on this upper ,
Bought a PANTHER AR .308 DPMS Gen 1 LOWER FOR IT , IT FITS PERFECT like its made for this upper ,
the mags slide in nice and easy and fall out when you hit the mag release . I`m ready to go .
HAPPY SHOOTING MY FRIENDS

Waiting on a Panther DPMS 1st Gen AR 308 lower to try it with , with adjustable gas which it has , and the different buffer springs on the market I`d think any short strokes can be delt with easily by simple gas adjustment or spring exchange . Can`t wait to try it out I love to tinker anyway . I`ll write a follow up when I get it all together . Good luck my friends .

Fits on top of my lower perfect. Smooth shooting. Lubed really nice. No jams or misfire yet. Comes with nice flip ups sights.

It fits perfectly an is already well lubed. Very smooth shooting.

Awesome conversion from AR10 lower to a 12gauge upper , love it
