I've had good experiences mostly from Combat Armory. Prices were super-cheap on sale items in the past, and until ~last week they offered free shipping on orders $15 and up. Their Glock Strikers (Firing Pins) seem okay, though a little 'looser' than OEM, and they subsequently rattle more. Could be a way to fix a 'too tight' Build situation caused by Cerakote getting into the Striker Channel I suppose... Springs aren't up to OEM spec, but close enough that they work, I can't recall ever buying any of their polymer components though.
There were more than a few complaints about their Trigger Housings, IIRC -I never bought one though. I did try one of their Glock barrels, and was NOT impressed. Aside from the finish not being what I expected, sharp machining edges and a hood cut too short to even make contact with the Breach Face brought my opinion of it below ever wanting to buy another one. It also fit loosely enough in lock-up to remind me of a run-out barrel with 5,000 rounds through it... I've run it, it fed well enough and was more accurate than I am, despite the loose lock-up. But it should have been better, I would buy AIM Surplus' target-crowned/flush-cut "Blem" barrels all day over the ones from CA.
I've seen I think a couple of their AR parts, they seemed okay but again maybe on the loose end of tolerances, though I am not much of an AR expert. I wasn't happy that they bumped some 'sale' priced items up 100% while they were in my cart, and still proudly advertised them as 'on sale'. My fault for not pulling the trigger (so to speak) faster, but it reminded me of Lone Wolf's shenanigans when the new owners took charge... CA also started charging shipping fees at the same time, so I passed on placing the order altogether this time around.
They are a decent company overall though, and I don't think I've heard anyone complain about their complete AR Uppers...
