I scored a couple of the magazine on the left from Daniel over at Kaneohe gun shop a few years ago. He said they were old stock gave them to me cheap I don't know the brand but it works really good!! Never had a failure even after leaving the mag loaded for a few months. Other than that magazine I've always had no problem with my factory colt x39 20rd mags only problem is finding them for sale lol. Asc 28's suck. Lol

That's a different looking magazine

How have the ASC 10s and 20s been working ?

And what brand upper are you folks running with what mags?

I picked up a PSA mid-length upper and a few ASC 10 and 20 round mags.

I'll report back on my experience after Junior's baseball season ends and I get a chance to try it out.

I only got the asc in 30 round capacity
Let us know how it shoots

Have you looked into that PSA KS-47 lower? Uses standard ar lower parts, but uses ak mags! I believe it's compatible with any 7.62 x39 ar upper. I love mine!

Those appear to be "frankenmags" or so they designated that term for them. Idk the exact manufacturer .

I run a home piece'd upper. With asc 20 rounders and 10's with the dremeling mods all have run flawless. Except 1 fail to feed. I blame ammo though cause the bullet was seated crooked. It was fiocchi x39 factory ammo. Still got plenty crooked ones to shoot hahah. I'll use it in my ak tho. AE ammo is flawless for me and pretty darn accurate. Similar to stangs groupings.

Baracus...

I think it's a proprietary upper for te ks47. I think on te website it only accepts their upper. I'll check again later to be sure.

Iraqvet8888 did a good review on it.

Yeah. My whole thing was I just wanted to pop uppers and not deal with a different lower.

Wow!  That's quite a bit of work to ensure those uppers function properly.  Hope all of you get them sorted out. 

A shooting buddy just picked up a PSAK-47, which appears is a barreled receiver and then you complete the "build".  He was one of those who had 1 or 2 decent AKs a while back when they are good quality and at a good price, but then got rid of them.  He's now getting back into guns other than ARs.  He went with a DSA FAL recently and not this.

yes, it is a bit of work to get it to function properly.  although some people's uppers work without doing any work.  from what I read its hit or miss.
hopefully what I've done over the weekend will have it working properly.  will test it this weekend.   :thumbsup:

Yup agreed hit or miss. My faxon barrel was/ is gtg without dremeling the feed ramps. Upon first inspection I already noticed the ramps didn't have a taper to it. It was almost if not perfectly straight and definitely wider by like a millimeter. I got the flame fluted so I can't speak for the regular barrel.

You would think  if they just made an ar10 feed ramp on the ar15 extension (idk what ar10 feed ramps look like or if the same size but I assume it's not to fit 308 boolits) it'll save us consumers grief! Charge the extra $5 and i wouldn't complain haha!

After widening the feed ramps ever so slightly, I tested it today.
80 rounds of Tulammo. Zero feeding problems. I used c products mags. 10, 20, and 28 rounders.
Seems to be functioning good now.
Also I'm waiting on a wolf stronger hammer spring. Just an insurance policy for the hard Russian primers. Out of 240 rounds fired had 2 soft hammer strikes. Although looking at the primer it looks like it hit hard.
I already have the enhanced firing pin so after I put in the wolf hammer spring should be very reliable.   :thumbsup:

Good job bro,

Yup the wolff should make it run flawless. I'm actually wanting to disassemble my arx39 and sell the not needed parts lol. Nothing wrong, just want a 5.56 again.

I'm trying to negotiate with my girl to let me blow money on my rifle again lol. I made twin x39 rifles (only differences are barrels, muzzle brake handguards lengths, and I spray painted my rifle) everything is exact same haha. She loves the idea of spending the time and money to make a "his/ hers" kinda thing lol.

Anyways good luck and good job

Btw what buffer weight ya running? I gonna try run some tungsten weights.

Idk the buffer weight
Everything is milspec in the lower I only changed the stock to magpul
Also have a stronger buffer spring coming too
What are the advantages to running different buffer weights?

Softer "felt recoil"

By increasing weight the bolt will have to move more mass backwards. Thus longer lock time . But bolt going home will be more stronger as well. That'll help with bolt bounce. But we not need worry about that cause that's mainly a full auto thing.

According to others it'll slow down all perceived movement of bolt. And prolong your ar15 parts. Think of it as driving in traffic , stop and go. Stepping on accelerator hard is light weight bolt. Just letting off brake and moving forward without accelerating is a heavy buffer . The later scenario would mean your engine mounts will last longer.

Idk how much is true but increasing weight in my buffer from 4.3 oz (started with that) to 5.5 oz. my recoil feels more like a push than a snap.

That's just my opinion.

I weighed the buffer and its 3 oz.  idk I might change that out later, we'll see.

today I installed the wolf hammer spring and the chrome silicon buffer spring.  also changed to an ambidextrous charging handle bc the times a round did get stuck it was easier to clear with a larger charging handle. I could just grip a larger one better.  although now I shouldn't be getting any rounds stuck any more.

modifications I did to the rifle and mags so far:
dremel the front of the mags for more clearance (C products defense mags work better for me)
widen the feed ramps and smooth the sharp edges with dremel
enhanced firing pin (came with the assembled radical firearms upper)
wolf stronger firing spring
stronger buffer spring (JP enterprises chrome silicon spring)
Ambidextrous charging handle

Spikes T2 4oz buffer is on order

I installed the wolf hammer spring, Spikes T2 buffer, and JP enterprise chrome/silicon buffer spring and tested it at the range today
fired 60 rounds of Tula and zero problems.  the last 140 rounds had zero problems
it's working good now.   :thumbsup:
