Anybody Like It ?

Any Negative Issues?

AR pattern mags are the weak link.

We'll see. Working to finish one right now.

I went with Dura mag solely based on reviews. Hope they "work".

I had one 2 years ago - Got rid of it - the mags were rough if you got anything over 10 rounds IMHO
Fun to shoot though. I got into 300BO instead.

Well, so much for my plans. Always got the AK to fall back on. I did buy a bunch of 10 rounders too, so maybe it just gets relegated to "designated marksman" duty with a scope. Watch for my WTS post on the bigger mags!

The only issue I had was with the extractor and extractor spring. I had issues with FTE every once in a while and the casing looked really scratched up. I changed out the extractor and spring, and everything started to work fine. I bought duramags and ASC and both worked fine for me.

Well post up some deets on which make and model you went with!!

Do you think a different BCG might have been in order?

My initial bolt was a Spikes bolt and firing pin, got it from OpticsPlanet. Thought, it's a Spikes, so it should be good to go, negative. Eventually got an Extractor Kit from RedExArms. That helped out. As for using a different BCG, I had extra carriers so I just used those. The only difference in firing an AR cambered in 7.62x39 is the firing pin and bolt.

Don't know why they don't have the 7.62 extractor available, but that is where I got it from.

Bear Creek Arsenal has a dedicated 7.62x39 Bolt.

For caliber standardization reasons only, I decided to abandon my build. In anticipation I bought 6 ASC Mags. Two 30 rounders and Four 20 rounders. I'm going to have to find a home for these orphan's.

I've considered a 6.5 Grendel, but ammo price and availability is steering me away from it.

Getting harder to justify most of the "latest and greatest", particularly in our current climate. I have an itch to build a 375 Raptor version but that should about do it for me if I do.

I had a KS-47, it took the regular AK mags. I think it was one of my favorite rifles. dang accurate too. never had a issue with it, no jams, went bang every time.

 

[Michael888]

Mine works Great... NEVER an issue... I do have extra ejectors and bolt.

Mine is a lefty and very accurate.

I am enjoying mine. I built it on a Aero lower and the biggest problem I've had was light primer strikes with steel ammo. I found a upgraded hammer spring with an enhanced firing pin that has solved the problem. I have a post over in the AL forum about it.

A few years ago I bought a complete 16”upper from Sanders Armory. They don’t tell who actually make their components. It is surprisingly accurate with standard steel case ammo. I used it on a lower with a Rise Armament drop in trigger. I was having light primer strikes so I bought an enhanced firing pin from Red X and it started working every time.

After about 300 rounds I started having light primer strikes again. I thoroughly cleaned it and bought another Red X firing pin but still had light strikes. Switched to a standard mil-spec trigger and started working 100% again. Have not shot it much in the last year or so. I have have C Products Defense mags in 10, 20 and 28/30 round capacity as well as some ASC 28/30 rounders and have never had feeding issues. It does have a quite noticeable recoil compared to a 5.56 AR.

A 5.0 - 5.5 Buffer will tame that recoil of a x39 in a pistol.

Adjustable gas block may help too

C products dura mag is the way to go!

If I remember correctly I am running a T(h)3 spikes buffer and yes it did help with recoil.
