If it was what I had, it would work fine. I built this Mak-90 about 15 years ago and used it as a go to truck rifle for a few years. Its a fun build and its pretty handy but since then better options have come along and there are a few things I don't like compared to AR's that I have.
Fully loaded 30rd steel magazines are heavy.
No muzzle device and no way to attach one.
I have found that "scout" mounted optics aren't my thing.
Not much rail space on the handguard, and none on the receiver/dust cover.
7.62x39 factory ammo costs are on par with 5.56 now, while reloading costs for 7.62 are far higher than 5.56.
Limited bullet selection compared to 5.56.
In the event of supply chain disruption, I believe 7.62x39 will be harder to obtain than 5.56 simply due to the amount of domestic production.
I wanted a fixed stock at the time, now enough good folding stock options have come about that I'd far prefer a good folder.
I know that a lot of that has been mitigated since I built mine. I would relocate the Aimpoint and add a magnifier. Unfortunately due to state laws I cannot buy any parts specific to "assault" rifles, so all my evil black rifles are legally locked in the configuration I had the parts for when the law passed and in my haste to get my AR's where I wanted them before the law passed I overlooked my one AK.
