Out of spec lower. - A3 Industries Lower Receiver For Grand Power Stribog

Both me and my buddy purchased this lower for my stribog back in jan2025. I Sent it off to have is cerakoted to match, got it back, slammed a geissele trigger in it, k2+ grip, SI safety selector, would not cycle. Had a lot other project going on so set it aside for a few weeks until I had time to look at it. Buddy brought his over which uses the same trigger, selector combo, worked perfect from right the get. Pulled mine out and started swapping lowers. Mine would reset the hammer on both stribogs. His lower worked perfectly on both. While I had both lowers side by said… started to compare and notice. My lower ls rear take down pin hole is 1/8” higher then my buddy’s. I didn’t even have to put a caliper on it you can see it clear as the day is long.i put the lower back on my stribog. Noticed that when I put the rear takedown pin in, it caused a gap. Took the pin out and the gap closed but now the pin don’t fit. Funny thing is, if I leave the rear takedown out and zip tie the lower and upper together to hold them together, it runs perfect fine!! OK problem solved, the gap is causing the trigger to not reset, the lowers out of spec. Let me contact A3 and handle this under warranty. WRONG!!! Literally in my 20 yrs of being in this industry, hands down the worst customer service I’ve ever dealt with. Infact they even told me they can’t “do anything to help” because they have an agreement with OpticsPlanet to go through them. I don’t know what that has to do with warranty on an out of spec item?!?! Of further more tells me their last batch was out of spec and that most likely what I have in my possession. They literally offered. I help, told me to contact optics planet, for an order I did 3-4 months ago. On an item I sent and said cerakoted. Mind you, this is there top of the line stribog lower with both the billet boot catch and mag release, coming in at around 275.00 beans.

This company can get bent. I will forever share my experience with them. My solution will be to sleeve the rear takedown down holes on their POS lower, moving the holes up 1/8”. This is not something that the average person can do so they should be helping people out. do not buy from this company if you want CS.

This is exactly why I stay with midteir+ company’s and this is a prime example that just because something is expensive, don’t make it good. Company’s like DD, lmt, sig, geissele, BCM, lwrc, would never let this slide. Stop supporting these kind of company’s! That take your money and CS stops there.
