    Great investment. Drastically improved ergonomics being able to use my own preferred grip. Mag release paddle is more sturdy and I find the convenience features from the ambi bolt release and adjustable set screw to tighten tolerances between upper and lower receivers.

    It works great on my 10mm Stribog. I will be looking at upgrading my scar with Lingle now.

    Stribog lower

    Posted by Justin on Oct 5th 2026

    Got my two lowers in and learned they make one in fde now. I immediately contacted them to see if they'd replace one of my black ones with an fde and they said sure send it back. While I'm waiting on the fde one I've been playing with the one I did keep and while I haven't installed it yet the quality seems top notch. The oversized mag release and bolt release / catch are enough to warrant the purchase but being able to use AR triggers and grips is like the cherry on top. 10/10 would purchase again.

    Exceptionally Made

    Posted by James Reagan on May 26th 2026

    Haven’t installed my UMP lower. Still waiting on my Stribog to be delivered. That being said, the part is of the highest quality. Perfect in every way. I wish every premium part maker strove to deliver parts like this.

    Extremely great quality

    That was very impressed with the quality of the stribog 45 cal. Well worth the wait. As soon as the 9 mm gets in stock I will buy one of those too
