SP10 & SP45 Stribog UMP Lower

Perfect fit much better from stock lower.

This is exactly what it took to build a Stribog .45 Very excellent ...the fit up it 100%. If you own a Stribog, get one. ?

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.

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

Must have

Excellent product! Tough to snag, but well worth the effort. Lost a star due to the wobble when installed. The 3/4-inch tension screw provided was too short to fix the wobble, so I had to buy a 1-inch tension screw from Lingle's supplier to fix it. It's going to seem like you are stripping the screw when you tighten, with the 1", you are not, keep going. There are other options from the same supplier (Hex-Drive Long-Nose 18-8 Stainless Steel Spring Plunger 1/4"-28 Thread, 3-13 lb. Nose Force) that work well. Check the Stribog Reddit. I wish they had an FDE option. I saw one recently, no idea where the guy got it from, as I didn't see that option when I bought mine.

Excellent upgrade. The set screw has to be forced onto the lower the first time and takes finessing to get through the coating. Once it does, it made a big difference in tightness. INWT pins do work, A3 don’t. Get anti walk trigger pins.

Ive been a long standing customer of lingle since the beginning. Hes always put out amazing products and will continue to bet he puts out More competitive products as time goes on. The stribog 45 lower is exactly what I needed to put the finishing touches on my SS build.

Couldn't be happier! Being able to customize everything from the grip to triggers and safety selectors is a huge step up. I'm running a Geissele Super Dynamic 3 Gun trigger with radian safety selectors and it feels great. Definitely a step up from the polymer lower.
