Â I've seen the Yeager video where the barrel pin and barrel movement is shown--scary. In the video comments, Vlad notes that this video was made in 2019, before PSA released their AK clone, which is shaping up to be pretty good.

Markus Becker Posted November 21, 2020 Share Posted November 21, 2020 Ok, if American made AK are so questionable, where do the good AKs come from Americans buy? Pre import ban guns and post ban handmades both costing and arm and a leg? Link to comment Share on other sites More sharing options...

Pre import ban guns and post ban handmades both costing and arm and a leg? There are still a few imports. I have a Romanian WASR that I bought several years ago for $600-ish USD. Now they are pushing $800-1000. A couple of American companies have finally started releasing quality domestic AKs, that hopefully will be 'reasonable', around $1000 USD. This also depends on USian politics.  Link to comment Share on other sites More sharing options...
Markus Becker Posted November 22, 2020 Share Posted November 22, 2020 Thanks, how much do ARs of similar quality to the new US made AKs cost? Link to comment Share on other sites More sharing options...
Simon Tan Posted November 22, 2020 Share Posted November 22, 2020 What is AK quality? The benchmark for a long time after the ban on Russian imports (Saiga, Molot) was Arsenal(Bulgaria) SLR series. Those are now also unobtanium as Kazanlak is at full capacity servicing the middle east (Saudi, UAE etc. and clients). The major problem was the production of trunnions which need to be forged and machined. To save on this, they tried to use cast parts, with predictable results. Currently PSA and others are now starting to produce their own forged trunnions. These are doing quite nicely and will improve availability as well as pricing. Mark ups are mostly secondary and speculation. Rifle Dynamics is usually seen as the Yoda of AKs in the US. LOOOOONG time ago I gave Bill Geissele his first standing order for triggers. Today, he's a titan in the industry and his ALG AK trigger is really good. Link to comment Share on other sites More sharing options...

As Ruger is known by its proficiency in casting, I suppose that is the reason for not being Ruger-made AK clones.

A case of an overall bigger part that can take the stress even if it's made in a nominally weaker manner? Link to comment Share on other sites More sharing options...

Impact stresses could appear in a localized manner, especially near stress concentration areas. Link to comment Share on other sites More sharing options...
Markus Becker Posted November 22, 2020 Share Posted November 22, 2020 That could be it, or not ? Kinetic energy wise 7.62 is more powerful than 5.56. Not by much but it could be just enough to make a difference. OTOH, Ruger makes them in 7.62 too, don't they. It could be the dimensions. Or a combination of the two.  KP15 polymer lower! Polymer lowers can be done but not(!) on the same dimensions as aluminum lowers. I bet that goes for cast and forged steel as well. Link to comment Share on other sites More sharing options...
sunday Posted November 22, 2020 Share Posted November 22, 2020 (edited) I studied metallurgy and machine design back in the day, but the real small arms specialists here are Simon, and Bojan. I know that if one varies the dimensions of certain parts, you could reduce the stresses they should cope with. Case in point: by putting the locking surfaces the lock has to interface with in a barrel extension -using a rotating bolt, for instance- to you could use a lighter receiver, like on an AR15. If you use a mechanism with a flap locking in the receiver, then you shall use a beefier receiver, like on a BAR.

It jammed frequently and a trip to the gunsmith at the store where I bought it revealed that the piston was slightly...bent. After repair or replacement (I forget which was done) it runs great.  Link to comment Share on other sites More sharing options...
