"Boy is that lower nice, set screw to adjust receiver play, set screw pin for the bolt catch, flared mag well,"Got the lower parts kit ordered, for the hell of it i called one of my lgs and they had one aero m4e1 lower in stock for 139.99. Ended up going and picking it up lol. Boy is that lower nice, set screw to adjust receiver play, set screw pin for the bolt catch, flared mag well, im half tempted to swap it out with my psa lower on my pistol lol. If i wasnt so ocd about the psa logo lower matching the psa logo sba3 brace id swap it. Now i gotta try to wait for a good deal on a 7.62x39 upper. Bad when you almost have birthday shopping done but still need to shop for christmas lol
When you were shopping for a lower to build your pistol on, that's why I recommended the Aero as being that much better or should I say easier than darned near any other lower,not to mention feature rich.
BTW Aero has a brother/cousin company with AR and Glock products it's called Grey Ghost Precision. https://greyghostprecision.com/#
I have used their Glock parts and will not use any other than their Glock slide completion kit, all their strikers/FP.extractors are from billet stock.
Much like Glock used in their Gen 1 & 2's,before Glock went to investment cast and then more recently MiMed parts.
