‘93 Tula parts kit AKS-74U ‘Krink’. Grail gun. Can’t thank @shaefferzack @chefurcustom and especially @embacharmory for their work on this. The two greats of their generation having hands on this make it the priceless relic it is. by @shaefferzack

What a privilege it was to bring this 1896 Bergmann No. 3 back to life for a video @realbrandonherrera
@nikolas_koval and I spent a few months reverse engineering the ammo and making fresh cartridges from scratch
The video documenting this several month process is live now on @pepperboxtv.
I also have a blog post up on my website with a lot of the technical details.
Each picture has its own caption

The crazy lock work of the set trigger

Various attempts at machining the casings. We don't have a CNC lathe, so it was done painstakingly on the mill. by @shaefferzack

I designed a copy of these bizarre North Korean muzzle devices a few years ago, and forgot about it.
Justin from @jmaccustoms reached out asking if I had any muzzle devices I wanted to make and these came to mind.
So we collaborated on it.
These are available at Chefur Custom, JMac Customs, and Atlantic Firearms

⁠
The AKS-74U, or more commonly known as the “Krink.” 🔥 This one was built by my talented friend @akayjohn78 of Appalachian Gunwerks in Winchester, Virginia.⁠
⁠
This is built off the Krink 5.45 kit by @shaefferzack of Chefur Customs with a lower AK-74 receiver from @recreatorblanks. Internals are WBP Polish parts from @armsofamerica with an @algdefense trigger. Beautiful hand guard furniture from @combloc_customs and finished off with @intlmilco Russian Black paint.⁠
⁠
I may be biased, but I think this is one of the most beautiful AKs I have taken photos of!⁠
