I have tens of thousands of the tungsten-core 5.45 rounds just because it was so cheap.
I then went out and built a couple AK-74s.*
(For other readers, yes 74, not 47.)
Milady, trained by the USAF Security Forces for base defence, got pretty good with the M16A2 for a mechanic, but she really doesn't care for either it or the M4.
But after she got out, she discovered the 5,45mm version of the Romanian SAR-3 AK74. Being a notorious motorcyclist and under-the-truck-seat user, finds the folding Romy/Polish/East German *crutch* sidefolding wire buttstock to be just the ticket. Even with the fairly narrow buttplate of the folder, the minimal recoil of the 5,45 means *no problem* for her. And what she saves on AR15 accessories, she spends on East German and Polish 5,45 magazines.
I remain fond of the original 7,62x39mm M43 chambering, and have both a Romy G and a Polish underfolder AKS. But it's the RPK versions that really get the job done, in either caliber.
Very wise my friend!
Mil-surp is now banned from import, so you got in when you could, and wisely so! 7N6 doesn’t have tungsten though—it’s mild steel that will still penetrate 1/4 inch steel. 7N22 is the tungsten core variant. If you have that, I’ll be interested to know how you got it since I’ve never seen it before in the states. 7N10 was imported very sparingly.
I’ve shot AR’s, and 47’s, and there is nothing like a 74.
My brother was a Marine (3rd Division) in Iraq/Afghanistan for several tours. The Romanians they worked with used 74’s and he said that gun turned “insurgents” into jello.
Brother-in-law worked contracting in Afghanistan and he got hold of an AK-105. He said the round would penetrate windshield glass way better than any M16/M4 he used.
