SP10 & SP45 Stribog UMP Lower

Excellent quality. Great finish and fit Expected no less

The plastic lower from the factory was an insult to this fine weapon. Got this Lingle aluminum one and everything is better. Any AR grip, any AR safety and any AR trigger group without having to shim it in that plastic POS. The plastic grip especially was way to small. The only thing you need is the pins. Just give them a tap with a punch and they pop right out the plastic one and reverse to install in the Lingle. I used a CMC 3.5 LB Flat trigger and a Rock River Arms Star safety. The detent is very positive with audible and felt clicks on and off, perfect. The mag has a lot less wiggle in the Lingle, it was sloppy in the plastic lower. Additionally the mag release button has a much stiffer spring. The factory mag release spring was WAY too weak. I would have liked to have the push button mag release as well but whatever...you do have multiple bolt release options. It looks great, fits tight, didn't need the tension screw at all. There is no downside to this lower, it's WORLDS better than factory. Buy it.

This thing is the shiznit! Customer service is the best I’ve experienced from any manufacturer too. Will be purchasing from again here soon.

Really great product. Runs flawlessly. It’s awesome that I can run the same grip, safety selector, and trigger as my ARs. I’m big on standardization of firearm controls if it’s possible.

I was very excited to get one of these aluminum lowers for my Stribog sp45a3. I love the gun overall but immediately didn’t like the original polymer lower that comes on it. It just felt cheap, the stock trigger is trash, the grip doesn’t feel especially good, the bolt release is shit and it just doesn’t look nearly as good. This aluminum lower that lingle industries makes fixes all of it. It looks sexy, gives you tons of quality options for AR-15 triggers and grips (not ALL AR triggers will fit though) and the enhanced bolt release is much better. The only nit picking I could do is the black coating on the lower seems to be pretty soft and scratches fairly easy and wish it would have came installed with take down pins and springs all ready to go as removing the ones from the original lower is a little bit annoying and if you damage or lose the springs you’re gonna have a hard time getting replacements without a long waits shipping them from Europe, but with some patience and care it’s not a big deal. Overall I would definitely recommend getting one of these if you want to make an already nice piece way more badass.

High quality lower! I have a LWRC 45 that is now for sale because this lower solved the plastic issue I had with the Stribog.... Game changer!
