Most Helpful Positive Review Great upper so far
Very well built upper I do not recommend a 308 buffer spring unless you're using high brass shells I suggest using a basic AR-15 buffer spring for smoother action
Most Helpful Negative Review Parts fit but poor documentation
The upper fit to the dpms lower and the mags fit snugly in the well. Package lacks documentation - the three chokes are unmarked as to what choke, (impr cyl, mod, full) they are, no recommended shell type (low brass v. tall brass), nor size (2 3/4 or 3") provided either. Would expect more informatio...

Lower for IMG AR12 UPPER .

by Eugene, Verified Owner from PA, United States Written on August 3, 2025
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 .
Pros:
  • good solid upper
Cons:
  • You will need to tinker
Would recommend: Yes

Close but no cigar

by Eugene, Verified Owner from PA, United States Written on July 28, 2025
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 .
Pros:
  • Its close enough to alter
Cons:
  • I hate altering anything permanently
Best Used for:
  • The correct fit
Would recommend: Yes

MADE BY PANZER ARMS for IMG

by Eugene, Verified Owner from PA, United States Written on July 9, 2025
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
Pros:
  • FUN AS "HECK" TO SHOOT
Cons:
  • AMMO`S TO EXPENSIVE THESE DAYS
Best Used for:
  • Blowing things apart
Would recommend: Yes

Pretty well built upper

by Eugene, Verified Owner from PA, United States Written on June 30, 2025
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 .

IMG 12 giage upper

by Big Al, Verified Owner from AZ, United States Written on June 14, 2024
Tried it on a few lowers. Works on Alex Pro best. The mags are proprietary. I have tried multiple aftermarket mags none work. The mags feed fine in the Alex pro lower. I changed the spring to an AR 15 spring and it runs bird shot fine. With ar10 buffer spring anything under 1300 FPS will short stroke. Again! AR 10s are not mil spec. So do ur due diligence . It’s not a perfect match when trying to fit DPMS versions. I run into it All the time.

There is a reason no video can be found on this.

by Jack Payne, Verified Owner from WA, United States Written on April 28, 2024
Junk! The bolt doesn't go back far enough to feed or eject. I dropped a round in the barrel and it fires. Then take out the magazine put it on safe and dig out the spent round with a knife. The bolt hold open engagement works. So its either bad design or bad magazine that it comes with. I'm going to buy some different magazines and see if that works. Don't waste your money and time on this!

IMG 12 guahe conversion

by Big Al, Verified Owner from AZ, United States Written on April 11, 2024
Received upper quickly, goes for most items if they are in stock. Fit an Alex Pro AR10 lower dpms gen 1 compatible. Fitmen was super tight, but got it squeezed in. Cycles with mags. Can’t wait to shoot some clays . Will let u know how it runs with high and low brass also will check buffers and springs. Can anyone find magazines for this? Tried black river and does not stay seated.
Would recommend: Yes
