    Stribog Scorpion Lower

    Posted by Evan Morris on Mar 30th 2021

    I got my in stock notification and ordered immediately. Received it 5 days later. I was very impressed with the quality. It was only obvious it was 3D printed when looking carefully at the curved area above the pistol grip tang. Assembly was easy. The hardest part is the grip screw, since the square nut they include slides out easily. I recommend a cap of silicone or similar to hold it in place. Lingle could make that an interference fit, like the trigger and hammer pin holes and solve the problem. Just my .02. On the range, I fired 3 full mags, now a satisfying 105 rounds through. The first mag had two failures to chamber, but then it settled down and was perfectly reliable for the rest. This sort of thing is common with new systems, so I won’t dock it any points, but wanted you to know. I also noted that the mags don’t seat fully unless the bolt is back. I don’t recall that being an issue before. Anyway, it’s very minor, just have to adjust. Overall, I’m very happy. This opens up the platform to many possibilities and although I haven’t had any problems with my old Stribog OEM magazines.....yet. The Scorpion mags do have a MUCH better reputation. The extra 5 rounds are nice too.

    Excellent product, amazing customer support

    I encountered a user error while trying to assemble my lower to the stribog upper, sent a note and received a quick response. Excellent customer support.. Nothing wrong with the product, was my own fault. The Lingle lower is an great product and fits perfectly, even with the tail hook PDW brace. I’ve seen previous complaints with this, but it fits like a glove. A must have for any stribog owner!!

    Fantastic upgrade. Helped with my reliability issues and has been feeding HP and JHP bullets perfectly. The ability to use an aftermarket AR trigger makes this upgrade worth all the money spent.

    CZ Lower Review

    Posted by Joey on Jan 22nd 2021

    Absolute pleasure to run. Zero malfunctions after the first couple hundred rounds. This included rapid fire & full 35rd magpul mag dump. LRBHO works great. Even sprinkled in some weak mechanics and still ran superb! Increased my confidence in the platform significantly. Such an awesome investment.

    This really cleans up the look of the bog nicely, appears factory and of course the scorpion mags look great too

    Stribog Scorpion Lower

    Posted by Alexander M on Jan 1st 2021

    STRIBOG Gen 1 with HBI Non-Reciprocating Bolt. Fit and Finish excellent. Works without issue with Mil-spec Trigger and Safety. Did not reset with my LaRue Tactical MBT-2 during dry fire. I did Shoot 140 115Gr FMJ Rounds using Magpul Scorpion Magazines without issue with LRBHO. Long term hoping this will be a solid upgrade to an already reliable firearm. Can't wait to see a metal version. Also, inside edge of magwell needs rounding as it's a little pointy.

    Ohh it's noiceee .. another outfit for my Stribog

    Posted by striggygood on Dec 26th 2020

    Stribog looks good with CZ mags! its a good easy build carrying over the familiar feel of ar-15 internals. Dropped in a PSA trigger pack without any issues and used a mil-spec safety. Saved myself the hassle of the retaining pin clips with the ILWT HK style pins My biggest gripe is the tiny grip screw. Why not a full sized one?? There is a slight gap in the mating lines between the upper and this receiver. I wanted to deduct 1/2 star for the grip screw however no option for that rating exists so i rounded up. Overall, pretty happy with it. Annoyed that my existing GP stick mags are essentially side-lined .. Big plus is the common mag share with my cz evo s1.

    Stribog lower

    Posted by Unknown on Dec 25th 2020

    I bought this just as a project. I’ve never had any issues with my Stribog. Totally impressed with this part. I always, when I get something new, try and find something I don’t like about it. Kinda hard to do with this. The grip screw is kinda small is all I could come up with. Not even a real issue lol. Assembly was easy, if you’ve ever done anything with an ar15 before. Most people buying this have probably have a bunch of take off parts that could be used for this. I didn’t go that route though. I’ve never had issues with my Stribog , but if this upgrade is within your means, do it. Go ahead and buy the upgrade pins from ilwt too. Thank me later. Thanks for a great product Lingle Industries!!

    Stribog Scorpion Lower

    Posted by Shayn on Dec 22nd 2020

    After approximately 1,000 rds down range.... THIS THING ROCKS!! No fail to; eject, feed or fire from high quality to low quality ammo. Magpul mags lock up nicely and are very reliable in the stribog. Fit and finish is great! Big plus is ability to use AR grips, trigger and safety. That being said I put a LE145 rise armament trigger in, and it turned this pistol into something totally different... Better than the mpx or scorpion too LMAO! This lower is what saved the stribog after suffering from the OEM terrible mags that would randomly blow apart. GOOD JOB LINGLE INDUSTRIES!!!

    Game Changer

    Posted by SomeGuyWhoShoots on Dec 22nd 2020

    The fit and finish is awesome! I was honestly a little skeptical but when i finally received it, i was glad I ordered one. Thanks Lingle Industries for this! Highly recommend getting it with the Strike Industries mag release. Finally, a solution that has been plaguing us ‘Bog owners with terrible mags.
