PSA KS-47 + Csspecs 65G mag + 65G AR Upper

[AP Smizzlers]

Hi Horde!

I've come up with an idea and I'm looking for feedback.

Why not get a Palmetto State Armory KS-47 lower, marry it with a CSSpecs 30 round AK Grendel magazine, attach an AR 6.5G upper and have the best of all worlds?

CSSpecs has a note about their springs and followers having issues but I talked with them on Thursday and it sounds like that has been resolved and shipping will start within the month.

I asked them about this idea and their answer was "we haven't tested that but it sounds like a great idea, and would help us sell a lot more of these magazines."

I'm seriously considering putting one together once the mags are for sale and see how it goes. Thoughts?

May be a winner if you like the AK style of magazine release and inserting. I find the AR system much better.
I wouldn't think there is a greater COAL capacity in the AK mag? Might be a plus or minus there.

Oh, I thinks Gavin said there are some parts that would not be interchangeable so if you wanted a different trigger for example it could be a problem.
Get one, try it out and post your results!

There are two versions of the Csspecs magazines, Vepr and AK so I assume you?d want to use the AK mag. I think the receiver is longer on the Molot Vepr compared the AK-47 lower receiver. The advantage of the Vepr is long stroke gas piston and possibly a stronger bolt design compared to an AR-15 6.5 Grendel upper. The Vepr in 6.5 Grendel requires more work to change the stock and pistol grip and I don?t think the barrel has a threaded muzzle.


Sounds like a doable build and would probably prove to be more accurate than the Vepr 6.5 Grendel.

I originally saw the VEPR 6.5 Grendel version of the magazine and was going to buy one (rifle and magazine) but the standard AK version appealed for the AK/AR Grendel mashup idea.

Also, if the idea is a failure for some reason, I could make a 7.62x39 pistol out of it.

If you do it. Order a 7.62x39 pmag as well and let us know how it works out with grendel.

Not to hijack the thread, but if MagPul can make a 7.63x39 polymer mag, why can't they make a 6.5 Grendel?

Two very diffrent mag well designs that's why.

I know guys at the range that tried 7.62 x 39 P mags in 6.5 Grendel,jams. They’ve also taken 6.5 Grendel magazines apart and tried to put the followers in P mags ,jams.
P mags are my to go to mag for .223 or 300BO. Flawless never had a jam.I’ve emailed mag pool before and asked about a 6.5 Grendel p mag, they said they are working on it. But up to now they haven’t been able to design one that works flawlessly. So I wouldn’t hold my breath waiting for a P mag in 6.5 Grendel, it may never happen.

You would be the first person in history magpul as told that too.

The rest of us they have and continue to tell us they are not interested in making a 6.5 grendel pmag because the mag walls would be too thin to fit the ar15 legacy magwell.

Now they can and should build a 6.5 grendel pmag to fit the six8 sized recivers.

Or a PMag to fit an AK receiver with 6.5 Grendel AK magazine.

Because the lower will only work with PSA KS 47 uppers.

And stripped the upper down and drop a 6.5 grendel barrel into.

Bam ks-47/6.5mm grendel.

Ive had the same ideal for a while, Have a sbr'd KS47 receiver sitting in a drawer for 2 years that I havent built, I was going to use my faxon GB 12" on it but ended up building that on a normal ar SBR receiver. If you end up doing it please post results and mag function im very interested.

[m796rider]

ETA: I have parts inbound from PSA -- let's find out if this works.

This is an interesting idea... I'm actually thinking about taking my 12" Faxon barreled AR upper and combining it with a KS-47 upper/pistol lower/BCG.

My biggest concern is headspacing -- I'm stuck using the proprietary KS-47 bolt which is cut to work with AK mags and has the common 7.62x39 0.125" bolt face depth.

Might look something like this with a CSSpecs 30 round 6.5G AK mag (looks a bit goofy IMHO):

So it sounds like a Type 1 chambered barrel would be needed. I'm curious if the conventional barrel extension will work with that setup, the PSA KS-47's have a large single feed ramp.
