One quick question on ammo.  You mention that you're using Wolf steel case ammo (in the grey cases).  Are the WASR's that have gone 100K rounds done so with these bi-metallic rounds?  I ask as similar bimetallic rounds can chew through AR barrels (throats, gas holes) in 10K-20K rounds.  

If so, those are some durable eastern block chrome lined barrels!!


To be fair, comparing 5.56 to the significantly slower 7.63x39 isn't a good comparison from a wear perspective.



Also, BFV is using their guns for full-auto at close range. They don't consider a barrel to be "shot out" unless its key-holing at 25m (or is it 15? It's somewhere in this thread). Any other user would have long since replaced their barrel by then.

Bump for an awesome thread. Now I'm reconsidering my potential N-PAP purchase, at least at the current price point.

Ron,

Any chance you guys have fielded some of the newer VEPR rifles from FIME/MSR?

After reading how well your VEPR-12's were holding up, I'm curious to know if they're still doing well, and if you've decided to acquire some of their "rifle brethren" or not.

We don't have any of the VEPR rifles on the line but we do have a Saiga 7.62x39 conversion for customers who HAVE to shoot a real Russian weapon. As for the VEPR-12's not one single failure since they've been put on the line.

I haven't updated this thread with any new info lately but I was talking to the armorers about the 9mm AK's we got from Atlantic Arms. Those things are still running strong with no broken parts and zero issues. We've had two of them on the line (both running suppressed) for a little over/under 12 months and they are running flawlessly. It's a GREAT weapon for females or younger kids that just don't have the size and weight to handle a 7.62x39 AK variant properly in our range.

On another note, we are going to test a couple different AK's on the range. Since this thread was started in order to help the average shooter on what works and what doesn't work, we are going to build several AK's from flats. Some receivers will get the "home"-made type of heat treating and others will get proper heat treating from a facility that specializes in it. I want to do some hard testing and see how well they hold up to a factory WASR or Arsenal. We will be using both chrome-line and nitride barrels and see if we notice any difference.

If you wouldn't mind, please install a buffer in one or two of them. It would be nice to see if buffers do or do not cause damage over time (so long as the guns run with them installed, that is).

I believe I made mention and I'm not sure what the relationship between IO and Pioneer Arms is but those AK's did not last. Trunions cracked within days and other catastrophic failures. We took them off the line, welded up in the inside of the receiver, punched the barrel, destroyed bolt face and welded all back together to use as a display gun for customers.

Pioneer Arms were made in Poland and contracted by IO. They used the same build practices and, as far as I know, parts as IO does. IO was trying to capitalize on the "Radom" name by fooling people into thinking the rifles came from the FB Radom plant, when in fact they were just in the same town.

Honestly one of the best threads probably on the internet.  Thanks for keeping us update and informed along the way with so much information.  Just had two questions, one since I rolled the dice on a C93v2 not too long ago I was wondering how well they are holding up since hopefully the round count should be up? I didn't see any updates with exploded rifles so thinking they are still chugging along just fine and also I was curious about your krinks and how they are doing specifically if you guys had any SLR-104UR's online, thanks?!

The C93V2 doesn't get as much use the standard WASR's but it hasn't suffered from anything breaking at this point. The carrier still looks decent, no noticeable wear or "egging" of the hammer/trigger pin holes and it's still shooting "straight".

AKOU has plenty of experience with breaking RAS47's in semi-auto. If Ron has any on the line, I'd assume they're breaking left and right.

He has some and at last count they were doing fine. The C39V2 only shares the bolt and carrier with the RAS47, and only some of the bolts suffered from poor heat treatment, not all. The C396V2 is a milled receiver which is not made by Century, so none of the rivet problems, trunion and head spacing issues of the RAS47. Further, the V2 resolved all issues associated with the C39 original like the sling mount points and the like.

The V2 addressed a list of problems from the original , none of which affected function other than a run of soft bolts early on, and they upgraded the barrels to a Green Mountain melonite barrel, which has proven very accurate for an AK. They also went to Wolff springs  , where the original springs were not the correct poundage, resulting in some peening on the rear of the bolt carrier tail and the receiver.

I still plan to replace the bolt and carrier with a Polish one, but the rifles are fine. I still wouldn't buy a RAS47 due to Century's rivet mishaps.  

This thread is great for information, let's not fill it up with conjecture and misinformation with comparisons to rifles that aren't remotely the same.

I wasn't even talking about the C39, thank you. Got one of the early models myself, right after they started lining the bore with chrome.

My bad. I apologize.

I will point out though that the V2 uses a melonite instead of chrome lined like on the C39, both good barrels.

Agreed, the green mountain barrels are superb, and the C39's tend to be fairly accurate.

Mine is a little odd, though. I was able to snap off more than a few sub-MOA to 1.25 MOA 5-shot groups with Golden Tiger, but I have yet to find any brass cased ammo that holds tighter than 3 MOA.

Well maybe, but it seems the RAS47 made it to 5000 rounds, barely.  Can't say that for the DDI.

Barely sounds about right, it was falling apart. Hell, the stock was held on with duct tape. Cheesy furniture aside, Century's rivets still scare the shit out of me, and the wear patters on the bolt were concerning. Like Rob says, I wouldn't recommend a RAS47 to anyone.

I'd say DDI deserves a chance to work out the extractor issue, since they just introduced their rifle. Looked to me like they had bad heat treat on the extractors, or they used a steel that was too hard and brittle. I was hoping they would've hit one out of the park with that, too, but it's for the best that they find out about the extractor issue earlier, rather than later. Given time, they'll find and fix the issue.

I'm wondering if they could just order extractors from Bulgaria or some other combloc country until they can produce their own in-house extractors that don't have issues. If I had the money to burn, I'd pick up one of their triangle stock models and swap the extractor for a surplus one, see if makes a difference.

I wasn't aware that Atlantic had 9mm AK's, that may be something I'll look into...

I'm interested in seeing the results of your heat treating test, I've never done mine at home, I use the Polish blanks and I've always sent the receiver out to be properly heat treated but always wondered if the home treated receiver could withstand the same amount of abuse/round count...

Much appreciate your input on this thread...and its on my bucket list to one day visit BFL, in fact I was just telling my wife we should go there for our 25th anniversary, she gave me the "nice try" look...LOL

Thanks Ron. Not that I run my Atlantic 9mm AK as hard as you guys but it comes to the range with me every time I go. I've fed it nothing but craptastic ammo and it continues to run without any signs of major wear or broken parts.

We lost several AK's over the last 2-3 weeks and it's MY opinion that had we changed recoil springs sooner AND had a buffer inside the action, we wouldn't have lost that many.

Also.. we are going to put our first AK on the line that was made with a AK-Builder flat and heat-treated with the MAPP gas method. Not trying to destroy anything on purpose, just want to test and research for ourselves if having the whole receiver heat-treated will make a difference under heavy use.

Very interesting. If you could, would it be possible to have one rifle using just a buffer and one that you just change out the recoil spring on a regular basis? I've been pretty vocal about not using buffers, but will certainly say I've been wrong given enough data.

I agree. If you could test with buffer and without, that would be pretty interesting. Lots of folks are anti-buffer, but with the volume you guys are running at, it would be tough to dispute your findings.

Are you saying that changing to wolf springs will stop peening on the bolt carrier tail, while not affecting cycling?  Is there some spring poundage number that is different, optimum?  Are you saying it is not a carrier tail metal hardness issue?

Is it correct that changing to a Polish carrier and bolt will require headspacing?  Changing headspacing requires the capability of pressing the barrel further in or pulling it fractionally out, is that right?

The V2 addressed a list of problems from the original , none of which affected function other than a run of soft bolts early on, and they upgraded the barrels to a Green Mountain melonite barrel, which has proven very accurate for an AK. They also went to Wolff springs  , where the original springs were not the correct poundage, resulting in some peening on the rear of the bolt carrier tail and the receiver.

I still plan to replace the bolt and carrier with a Polish one, but the rifles are fine. I still wouldn't buy a RAS47 due to Century's rivet mishaps.  

This thread is great for information, let's not fill it up with conjecture and misinformation with comparisons to rifles that aren't remotely the same.
Are you saying that changing to wolf springs will stop peening on the bolt carrier tail, while not affecting cycling?  Is there some spring poundage number that is different, optimum?  Are you saying it is not a carrier tail metal hardness issue?

Is it correct that changing to a Polish carrier and bolt will require headspacing?  Changing headspacing requires the capability of pressing the barrel further in or pulling it fractionally out, is that right?
you can switch bolts/carriers, but you have to check headspace with GO/NO GO gauges to make sure it will function. It's inadvisable to bother with a different bolt or carrier unless there is a problem with the existing one that affects function, because fixing a headspace problem is a PITA.

Early C39s had weak action springs. Changin  to a stronger one prevents the carrier tail from slamming into the receiver.

Peening is a problem with the spring, not carrier hardness. If the carrier is soft, it will peen. If the carrier is hard, the receiver will peen. Fuck all that, switch recoil springs and be done with the peen altogether.(Hey, my sister said something similar, once. )

The C39V2 had only one main issue; the lack of a side rail. Century engineers followed the centuries-old  tradition of Russian engineers and got piss-drunk on vodka, said "FUCK IT!" and designed their own side rail instead of getting $3 surplus rails, or licensing the mastermount side rail.

The recoil spring has zero effect on the bolt carrier tail as the tail does not contact the rear trunnion or receiver at any point during cycling.

Right right, carrier tail hits the hammer, my bad. Can't remember what it was century put out that had problems with the carrier impacting the rear of the receiver, thought it was a problem with their AK's...

Methinks i need to stop posting while drunk.

Do you have any 5.56mm AKs on the line?

I'm also curious about the 7.62x39 vs 5.45x39 durability and even barrel life even though I'm positive the 5.45 will have a shorter barrel life.

What buffer do you guys use in the AKs? Link?

Any interest in acquiring a Dead Air PBS-1 Wolverine suppressor to use on an AK?

I'll ask the staff but I'm pretty sure the Romanian WASR barrels have outlasted the Arsenal 5.45 "Krinkov" barrels. The armorers recently re-barreled four of the Krinks with the chrome-lined barrels offered by AK-Builder.

You must be busy Ron. Started to miss reading your new inputs. I'm glad for one, the WASR is a good rifle for you. It's affordable and tough from your information. So I had to order one. Again, glad to hear from you. I hope business is going well.
