Yeah, I built a couple of those this year . Great looking guns but like all underfolders they suck to shoot and I sold them both.
I thought bout one of those and having both gas and front sight swapped with 74 ones but apparently swapping the gas block is quite a pain because holes don't line up.
Nice setup. You experience any of the overgassing issues people have been talking about? Also, the AK purist in me notices you need a cleaning rod in that SAM5
Yup, she got a kns piston in there!
