I hope this is the right place for this post. I also know that there are many similar threads to this. Looking for some insight on a potential next purchase. I'm split minded between -10.5 inch ar pistol built using this PSA kit (or similar). With an Aero lower. Running irons only. PSA 10.5" 5.56 NATO 1/7 Nitride Classic Shockwave Pistol Kit, Black - 5165449715 Or -12 gauge 870/500 or other 18.5/20 inch shotgun. Most likely used to save costs Either would be my "backup" road trip/camping/trunk gun. I EDC a P229 (9mm) and have an Aero M5E1 (.308) as a primary long arm with a 4.5-14 optic. I'm not unwilling to keep taking the M5, but I'm interested in getting something a little cheaper. I also have a .22 rifle.
