    So many times a product over promises and under delivers. This lower is the REAL DEAL. The milling and tolerances are perfect. Replaced my Stribog lower and said goodbye to those insufferable feed issues now that I can use real Scorpion mags. I can't praise this product and the folks at Lingle enough. It is great to see a company produce such a superior product.

    We bought 4 of these for builds. The tolerances are great and fit tight to the guns. Contrary to what some on Youtube have said the Magpul CZ mags fit tight and we have had no hiccups whatsoever. We built one up with a Franklin binary and another with a Timney. Both guns are fast and reliable. We are now building 2 more and adding short stroke buffers as well as some other goodies to them.

    Excellent fit

    Posted by Dave on Jun 25th 2021

    I planned to change my Stribog lower for the magazine availability, but after seeing a few Stribogs with ruined factory magazines, switching to Evo mags seemed an even better idea. This lower certainly delivers. Excellent fitment. Magpul magazines work best as I've had trouble seating factory Evo mags, but I can't complain since my majority are Magpul anyway. Installed with CMC PCC trigger, Radian Talon selector, HB Industries extended bolt release, and Magpul K2 grip.

    Thank God this lower exists to offer a great solution to the Stribog’s horrendously bad factory mags.

    Stribog aluminum

    Perfect. Finish is perfect. Fit is tight, but perfect. Trigger fit, safety fit was perfect. Trigger pins a bit short, but I just left the plate off and they fit and work fine. Using the "new" bolt release and the bolt hold open perfectly. I ran AKVs and Magpuls with no issue. I was using Blazer Brass 115 grains and a new A3 upper. That was the only hickup, but after 3-4 mag dumps, no issue and it ran smooth from then on. I think that's break in of the upper, and I'll run some 124 and 147 next visit. Really great product, and really great customer service.

    Magazines are way to sloppy in the well

    Posted by Brian Weckerly on Jun 11th 2021

    I bought this so I could fire hollow point ammo. While I am happy with almost everything, I am not happy how sloppy the magazine fits in the magwell. It has way to much fore and aft movement so that the ammo jams on the feed ramp. I was using Magpul 35 rnd mags. When firing fmj ammo it worked well. But I found I had to push the bottom of the magazine towards the front of the weapon to get hollow point ammo to reliably feed. This is due to the excessive play in the mag well.

    Took a while to find the right parts combination but it rocks now!

    Posted by Teddy Elarmo on Jun 9th 2021

    I think I got one of the first batches made. It didn't work smoothly right of the bat to no fault of the lower at all. With different parts source for my short stroke spacer, bolt stops and my different ammo profile/reloads I knew it was going to be a project. Kudos to Luke for working with me on finding the right combination of parts. I got the right sized enhanced bolt stop from another vendor, got my reloads in bot HP and Flat nose right, Wolfman suppressor, KD Gunwerx 3 stage damper and both AKV and PMAG with LRBHO working in harmony .. reliably. And now it works perfectly. Long road to reliability but it was a fun project and Lingle customer service was awesome. Buy with confidence. If you encounter a hickup.. Luke has your back.

    A work in progress

    Posted by Jack on Mar 30th 2021

    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.

    Aluminum stribog scorpion lower

    Posted by Myself on Mar 30th 2021

    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

    Posted by Dustin Clough on Mar 29th 2021

    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

    Posted by Carl on Mar 11th 2021

    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!!
