    A work in progress

    Out of the box the lower looked great. I liked the SI mag release. Elftman trigger, and sig ambi safety installed without issue. Monkeying with a magpul showed promise with dropping free and smooth engagement of the bho. The PSA mags were another story. Extremely tight. I contacted Lingle and am having mine swapped out with one from the next batch. Most of my on hand mags are PSA so hoping the change helps.

    This is the way to make your stribog the best it can be 100% improvment. This very high quality aluminum lower from Lingle industries is unmatched I couldn't be happier and the ability to use the curved mags fixes any feeding looks great feels great and performs great. If you own or plan to own a stribog this lower receiver from Lingle industries is what you need. I couldn't be more pleased. Pay attention to their web page for dates of availability when sold out. You need this lower

    worth the wait and the money

    love the product. worked great with magpul mags. my psa mags were snug but worked great. my only complaint is the tight tolerances. i had to use a dead blow Hanmer to tap on my grip, and my lower onto the upper. to seperate, i had to use a flat head screw driver. i will need to do some filing, just didn't have the time too.

    This exceeds my satisfaction. Great product and I'm glad I waited for the aluminum release. This is a must have product if you own a Stribog. Keep up the good work guys. If you get into making more aftermarket parts for the Stribog count me in. Their customer service is top tier. 5 Stars across the board.

    Totally impressed

    This is a must have fix for any stribog owner. The PSA AK-V mags were a little tight at first but are now amazing. The fit and finish is awesome, my big is now reliable and so are the mags, being able to have my bcm grip and geissele trigger make all the difference too. Honestly grandpower should just outsource their lower manufacturing to Lingle. 10/10 recomend!!

    Aluminum scorpion magazine lower

    Posted by Stephen S. on Mar 8th 2021

    Tight,right and pending actually being able to get more 9mm,outta sight! Being able to use my binary trigger is a huge plus(now I just need yet another lol) Has a thick parting line on the front of the magwell,though this is the only cosmetic blemish. The receiver is otherwise beautifully machined and thickly anodized.

    This is a much needed upgrade for the Stribog! Machining and tolerances are perfect. Worth every penny!
