first welcome to the forums 
second iāve not heard about this dimpling of receivers and trunions together before. What does dimpling them do that is so important? also can you explain what a swell neck is and what it does, and what its proper spec is? Dont get me wrong, im trying to understand your reasonings as to why all that is so important.
The ādimplingā is a couple of the rivet-holes in the front trunnion are slightly countersunk - and once the holes are located and drilled, the sheet metal of the receiver is displaced into it. Then pre-formed rivets (āswell neckā) are inserted and peened in place.
The idea is, thereās a little more surface-area and a bit of mechanical-interlocking to hold the front trunnion more securely. The Soviets didnāt do this from the outset, and Kalashnikov or one of his Engineers came up with it in response to some trunnions loosening under heavy use.
Recall that Soviet workers were somewhat less-than incentivized to ensure a solid fit and perfectly-tight rivets. This took a little of the āBubba-Tovarischeā factor out of the assembly.
Is it more Solid? Absolutely. Is it something that was an Oversight on Mikaelās part on the original AKMs? Debatable.
I would daresay there are original, Soviet-made AKMs floating around out there - probably somewhere in the Ukraine right about now - that are perfectly-serviceable rifles, with no issues, that have never seen nor heard of a Swellneck Rivet.
I just picked up an unfired GF-3, with low serial number 0001xx, can you add the years made on the generations list? It would be nice to know when it was made. Thank you
Welcome to the PSA community

iām fine with whatever you two wanna do at this point. i just spent time re-reading the stuff from january and i see nothing has changed now here in april.
so yeah, go for it gg and sp.
If anyone ever wanted a prime example of the toxicity of r/ak47, there you go.
Agree. People who think they know best, or claim to be the smartest in the room, are not. I know because i am around them every day. I love being at a meeting or training session and hearing someone say āthis is why i went and earned a Ph.D.ā. That is the point i really start to pay attention. Then later i usually find them at the hotel bar, where it is easy to play ā20 questionsā with them and embarass them in front of everyone because they rely more on their own ego instead of book or street smarts. Yes, i have a doctorate as well. But my āstreet smartsā, which mainly came from how my parents and grandparentās raised me, are far more valuable.
Iām just a dumb hick from the hills of PA, blessed to hang out with some really smart people, world class smart.
ditto, desert tho
Enough force and pressure to deform the rivet metal would probably also deform into the dimples the rivet is being mashed into.
Iāve read some folks putting down the PSA AK103 for not being a perfect clone of the Soviet rifle. I use and shoot my rifles. The basic AK has very good attributes, and the 103 adds some nice incremental improvements. As far as Iām concerned the PSA AK103 is an excellent rifle on itās merits, and I recommend it to anyone who wants a solid functional rifle that will give good service.
well your right about the folks who bash because the rifles are not perfect clones of the russians rifles, which to me is ridiculous, as if i wanted one to be an accurate representation, or clone of a russian 103, iād just buy one of those and be done with it. The fact is that PSA makes excellent AKs that are pretty dang good clones of the original Russian Models. Yes, sometimes the assembler may get over zealous and possibly put a bit more crush into some of the rivets, but that doesnt stop their AKās from running awesome and being just as reliable as any other AK 103 on the market.
I agree with your final assessment. If you want an excellent AK103 buy with confidence the PSA one is a solid functional rifle.
Hence what Iāve said from my first post on such about the swell neck / dimple thing. Iāve personally upset enough rivets by all means to fill my closet. PSA from examination doesnāt spinset the rivets. Itās a youtube hater creating his own bandwidth. I try to refrain from derogatory due to his claimed military service.
