Reviews & Ratings for A3 Industries Lower Receiver For Grand Power Stribog — 2 reviews — Page 1

Both me and my buddy purchased this lower for my stribog back in jan2025. I Sent it off to have is cerakoted to match, got it back, slammed a geissele trigger in it, k2+ grip, SI safety selector, would not cycle.

My lower ls rear take down pin hole is 1/8” higher then my buddy’s. I didn’t even have to put a caliper on it you can see it clear as the day is long.i put the lower back on my stribog. Noticed that when I put the rear takedown pin in, it caused a gap. Took the pin out and the gap closed but now the pin don’t fit.

I’ve added A LOT of things to my Stribog SP9A1, but I can’t believe I waited so long to get this. It’s the ultimate upgrade. I went with a Rise Rave trigger and a Radian Talon selector, and it’s a sweet sweet combo. Additionally the AR pistol grip is a fun way to customize your setup, and Scorpion mags feed hollow points and other ammo very reliably. Nothing negative to say about this lower. Every issue I had with my Stribog was fixed by this lower. It’s what the Stribog should have from the factory, and it brings a fun platform to a whole new level.
