Greetings Ron,

I have a Tiger SVD that has been fired very little and is safe Czar status.  I really love the rifle, and have been considering putting a lot more rounds through it.  I saw a few pages back that you put two tigers on the line in 2015.  Just wondering how those have worked out.  I know you did wear out the NDM-86 you were previously using.

Given the collectibility of the Tiger, and the scarce supply of parts I think all would understand my hesitation.  However, if there is one thing I have learned from all of the Battlefield posts, it is that military quality firearms can shoot an extraordinary amount of ammo.

Thanks,

Shawn

5.45x39 = 55k
7.62x54 = 58k
7.62x51 = 60k
30-06 (molot)  = 60k

More of Fuller's nonsense, he should stick to something he's qualified for, like "de-horning" (using sandpaper).

5.56 military loads can push 60k or higher depending on the load. If 5.56 ammo is run through .223 chamber the pressure can spike well over 60k.

Why do you think some 223 AKs have the more robust RPK/vepr style front trunion?  This is how the Yugoslavians were able to handle increased chamber pressure without blowing out the headspace at relatively low round counts.

I know all about that, it's why I own an M85NP, that's not all they did to accommodate the 5.56 in that pistol, chrome-lined bore and chamber on a CHF barrel too and 1.5mm receiver. It's the most overbuilt pistol i've ever seen.

But it's pure overkill.

Anybody really think something like a chicom type 84 is somehow weak and won't hold up to a lot of 5.56 down the pipe?

We did receive two of the PSA Gen 3 rifles last week. I will update Palmetto State on their performance on a regular basis and let them make updates. They are not paying us in any way for this "testing" as I would really like to have a source of quality-made AK's made here in the States.

Outstanding, thanks Ron, look forward to updates! I guess it goes without saying that the rest of us would also like a source of quality US-made AK's,

Ditto on the springs, cheap and sure can't hurt, bought some Thisbugger +5%'ers for all of the AKM's, great springs!

No way i'm putting a buffer in though. And i'll never need to go that far I think, semi-auto rifles that get shot a few times a year should be fine without 'em I reckon.

Understand, but my RPK is a transferable MG so I'm gonna err on the side of caution. My son would be pissed if I broke it.

@HendersonDefense

This may have been asked earlier in this massive thread, so if it has I apologize, but were your WASR's built with new production parts or demilled military parts (eg. 10/63's)? If it's both, have you noticed a difference between the two?

TIA.

Probably just utilizing available parts in inventory.
Zastavas were imported with rpk style recievers in 762 as well. O-pap i think?

The bulgarian 556 stamped AKs dont seem to need any additional reinforcements to accommodate the caliber, any more so than 762 or 545.

So the Bulgarian AK milled receivers have yet to fail, are these Arsenal SAM7’s (or similar models on the same receiver)? I’ve seen some say that stamped lasts longer than milled because milled receivers tend to crack where the barrel is pinned in (much like it does to the trunnion of a stamped AK) but the data you provide debunks that.

I'd be curious to see how well a KNS Adjustable gas piston and KNS Anti-Rotation FCG pins hold up to constant abuse; I wonder if you'd see any egging of the FCG pin holes, or if the piston would help decrease wear on the gun over time.

I don't understand why these are even made or why anyone would ever use one. AK pins are able to rotate by design, they're supposed to be that way.

And so are AR pins, the KNS pins do look very cool on an AR i'll grant you that, but rotating pins are a redundancy to guarantee the triggerset works even if the trigger and/or hammer are locked up on the pin due to rust or whatever, you are taking away an important feature, not adding one, this is NOT an upgrade at all but in fact a downgrade.

Probably nothing, lol. Even at BFLV these guns aren't going to get dropped or banged around too much, and they'll be constantly inspected. And being a civilian myself I can guarantee that unless the SHTF I probably will never have to worry about one of my pins rust-locking to a trigger.

I actually snagged a pair of anti-walk AK pins years ago from some guy off EBay, they weren't anti-rotation, just anti-walk with a threaded end on the safety side that takes a small screw, so ostensibly you didn't even need to use a sheperds hook/retaining plate on it. I never did put them in anything because their OD is at minimum dimensions so they are a little loosey-goosey when installed (plus the end piece doesn't screw in enough to lock the side-to-side play out, but that's probably best for this design anyway). But I do still think this idea has some merit if done right, but in the end it's still a solution looking for a problem like the KNS pins IMO.

Thanks so much for this thread! Wanted to know, how are the Krinkov SLR-104URs holding up? How long do barrels, receivers, and other parts last on these and how does this compare to full-length rifles?

Any updates on the mapp gas spot heat treat home builds btw?

I saw somewhere where people talked about some Polytech milled receivers having poor heat treatment, so my guess is it stemmed from there?  Arsenal receivers are very well made, and extremely strong.

I believe the arrangement between Henderson Defense and PSA called for Henderson to report back to PSA who would then release any results at their own discretion.

Oh, that's not a bad idea (assuming PSA gave them the guns).  Not as helpful to us, that's for sure, but much more beneficial to both of those businesses.
Link Posted: 10/16/2019 3:58:23 AM EST
PSA’s complete radio silence is deafening.  Perhaps someone who’s been to Battlefield can tell us whether they’ve had an opportunity to use one of the PSA AKs.  Just knowing they are still on the line would be encouraging.  PSA will have a tough time keeping up with demand next year if;

1.  They get good reports from Vegas, and

2.  They can build them fast enough to pay for their development

Link Posted: 10/29/2019 9:37:31 AM EST
Here's something that is about par for the course. This WASR-10 lasted three weeks shy of a full year on the range. The trunion will suffer a catastrophic crack on the right side and about 50% of the time it will also suffer a crack on the left side where the carrier engages it. The receiver rarely suffers a stress crack on the right from the bulge but strangely experiences a stress crack on the left side where there isn't a bulge in the receiver.

V/R
Ron
