    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

    Posted by Ryan Crawford on May 26th 2026

    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

    Excellent, but the wobble.

    Posted by LuisRJr on Apr 18th 2026

    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.

    Stribog 10mm

    Posted by Al on Mar 22nd 2026

    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.

    Stribog 45

    Posted by Rayne2ravage on Mar 18th 2026

    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.

    Stribog .45

    Posted by Kyle Paquet on Mar 17th 2026

    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.

    Sp10 lower

    Posted by Rohan on Mar 16th 2026

    The only reason I didn’t rate the sp10 5 stars is because Lingle doesn’t have the lower small parts to compete the assembly. The take down pins on the factory lower doesn’t provide a tight fit. So a 4 not 5

    SP45A3 game changer

    Posted by Carl Higgins on Mar 16th 2026

    The quality of this lower, is as the name suggest, a game changer. I'm beyond happy with the craftsmanship and ability to place G$ 3gun trigger in with a DFCO grip and the enlarged controls that come on this lower. To me this is a must have enhancement for anyone with a stribog 45acp or 10mm. Also the new GO mags and authentic HK mags run flawlessly in this lower and release easily.
