The hand grip is a US Palm battle grip, the but stock looks like a magpul zhukov and the for end is definitely not a magpul it looks more like the stock from a Saiga IZ 240 AK 74 Rifle. As a matter of fact the Saiga is sooo close but the trigger is too far to the rear.
You are correct on the furniture (stock, US Palm, Zhukov (you can see the cheek riser next to it) but a converted Saiga looks just like a regular AKM or AK74. I converted my Saiga 12 and move the trigger group forward.
FYI. I’ve done this numerous times to Saigas, this is why I’m adamant that it’s a Saiga.
You can convert the trigger group and pistol grip forward to the normal position of any Saiga regardless of caliber. Takes all of 5 minutes.
To convert the front handguard and gas tube is a bit more painstaking and this moron probably didn’t know how to do it. The original FSB needs to be drilled out, removed; the gas tube needs to be replaced with a standard AKM replacement and new handguard retainers need to be installed over the new tube and barrel. After this you can then either drill back the original FSB or replace it with a standard 24mm FSB that the AK-74 uses.
This whole process takes a few hours to get it right. Otherwise you’ll end up with a jerry-rigged cant or worse.
