New: CPD/Duramag 20 round 6.5 Grendel mag review.

[VASCAR2]

I received two new CPD/Duramag twenty round 6.5 Grendel magazines today. The fit and finish look very good. I like the matte finish and the magazines loaded easily. Both magazines held twenty Wolf steel case 100 grain FMJ ammo. The magazines fit and ejected from a couple of my lowers without issue.

Here are the two magazines and were shipped in the plastic package.



Here is a picture of a CPD/Duramag 20 round mag next to a E-Lander 17 round mag.



This picture shows the 20 round CPD/Duramag sitting on the E-L 17 round mag. The overall size is comparable to the E-L. I tend to prefer the matte finish on the CPD/D mags.

For size comparison here is a 17 round mag with a 20 round 5.56/223 mag next to the CPD/D 20 round mag.




This picture shows the E-L 17 round mag, curved body 20 round 5.56/223 mag next to a 20 round CPD/D.



This photo shows the 17 round E-L mag setting on the 20 round CPD/D to show difference in profile. The CPD/D is lighter and feels more like a traditional aluminum 5.56/223 mag. The E-Lander mags use a heavier gauge stainless steel and are significantly heavier than the CPD/D stainless steel mag.



For comparison 17 round E-L next to early 15 round C Products mag next to the 20 round CPD/D.

Same PSA pistol with 20 round CPD/D in well.




I just stepped out the back door and fired 20 rounds of Wolf FMJ steel case ammo at my 50 yard target. It was raining so not much of a test but all 20 rounds fed and ejected perfectly. The mag ejected from the well easily and this appears to be a great mag. I like the size, weight and appearance of this mag. I purchased these two mags from Aim Surplus for $18.95 each with free shipping. PA had the same CPD/D for $31 in stock. I think this will prove to be a popular mag for the 6.5 Grendel and 6 MM ARC. I hope CPD/D can keep their production quality high and get fewer lemons.

Thanks for the review sir. Well written.

I been saying for a good bit the CPD/ Duramag's are the best of the metal grendel mags. Their 10 and 26 round mags have been nearly 100% flawless for me except for one or two I had to tweak a feed lip on.

I decided to add three more pictures. The first picture is an ASC 25 round mag next to a 20 round CPD/Duramag.

I have 3 C Product Defense (CPD) 20 round 6.5 Grendel mags that I bought some time ago (don't remember when or from whom - can't find receipts might have been last January). I think they're stainless steel but their bodies are magnetic. They will hold 20 rounds but that last round is a tight squeeze. I believe the bodies are nitrited. They're definitely not painted like my Stoner 6.5 mags. They look a little different than the current CPD 20 rounders. On my mags the middle guide rib is wider & deeper for about the first 2 inches or so. I've had no issues with these mags. All 3 feed & function well.

VASCAR2... I can't see the followers in your photos. Is the hump on the left or right side? Mine are on the left... looking from the back of the mag. Also, do your mags have part or serial numbers stamped on them? I can see some stampings on the 20 rounders that I can't quite make out. Mine have what looks like laser engraving: CPD 6.5 Grendel (Painted over).

That's strange CPD said they have never made a 20 round grendel mag before now.

Are your mags stamped grendel anywheres? Wondering if someone passed off some 7.62x39 20 round mags as grendel mags.

You can't see it in my pics because I painted over it (Duracoated). It looks like CPD's logo followed by "CPD 6.5 Grendel" is laser engraved on the mags. I tried to remove the duracoat on one mag but nothing I have is aggressive/strong enough to remove it. I don't have any acetone. Attached is a screen shot of the logo from the Duramag website. It's the same as the one on my mags.

I wish I could remember where I got them. I'd say they have made 20 round mags before but maybe sold them as 17/18 rounders.
