Your link goes to an AofA page not found. Not really sure of your question either sorry? WBP kit + FB barrel + quality rivets & receiver = good rifle. That's about it, and yes the front trunnion is forged on these. Some of the other parts might be cast, but then again Factory #11, Radom started using cast parts in its military guns as far back as the late '70s, so not a problem.

The early WBP kits came with a cast front trunnion, which is what Rob has in these videos IIRC. WBP later started using forged front trunnions from radom because of the requests from customers that they received. However, Ive never heard anything bad about WBP's cast trunnions.

Yes, the switch was made quite some time ago, so any kit purchased from AofA within the last several months should have the milled trunnion.

I have owned and shot many AK's, I have never seen bolt carrier tail deformation of any com-bloc, or Chinese AKM, until the USA made AK's started arriving on the scene. Due to my experience in machining and heat treating, I think the carrier is either improperly heat treated, or made from a casting instead of being forged. I'm having a hard time believing it's the hammer's fault!

The carrier could very well be made from a casting...so what? Russia switched over to using cast carriers in what? 1973 or 1974?

OK, what is the big deal with pinging? Has it caused any malfunctions? has it ever lead to a carrier actually cracking or the tail breaking off? Has it murdered a Nun lately?

Its cosmetic. Its not the USA made AKs coming onto the seen. Its people examining every AK with a microscope after firing a few hundred or thousand rounds.
Every gun has wear points, and this is just one for the AK.

Here are pics of our fully machined trunnions. When it comes to bolts and bolt carriers the only manufacturing method we adopted is machining - we DO NOT use any castings for these parts.

See, there you go, straight from the horse's mouth as it were.

And again even if cast, if done properly, so what? Many military, select fire AKMs and AK74s came from a gov't factory with a cast bolt carrier. It shouldn't mater.
Agreed, the bolt and the front trunnion should be machined always, but with many other parts you can get away with a casting just fine.

One of my Chinese AKs has a bit of peening on its carrier, and it is all original including the FCG.
I've noticed on carriers out of used surplus parts kits too. Not extreme, extreme defformation but definitely a bit of flaring.


Anyhow, WBP while you are hanging out here, I just got one of the Atlantic CG1s built with your parts.
I put it side by side with a 1967 Polish kit gun and it stacked up nicely. The only differences were minor such as the lightning cuts on the front sight base and rear sight leaf.
What impresses me though is how closely you reproduced the laminated furniture.

Also been trying out 4 of your green 7.62x39 mags in various AKs. Even gave them a go in a Galil Ace.
So far, so good. No malfuctions or concerning wear on the locking lugs.

Thank you, we are very glad to hear that your initial impressions are positive.

Hi Chris, and by the way finished up my 'video' (actually 3 parts lol) on Polish AKs. I fear I am turning into the Nutnfancy of AKs and that i ramble too much. Maybe I should hire (i.e. pay in beer & cheap pizza) an editor? hehe

Bulgarian Bolt Carrier after several thousand rounds... NO tail deformation!
