I agree with all of what you said here. I have a sh*t load of Magpul stuff and some of it was like a deal and other felt like a splurge. It's all good stuff, though, but just higher than other brands.I agree that some things they sell are ridiculously priced. But some of their products are top notch. My last AR had their fixed carbine stock that gave it a clean minimalist look. I like the PMags too.
I wasn't always a Magpul fan. I used to see them the same as Tapco plastic ****. But it kinda grows on you. I have a Flat Dark Earth phone case for my Galaxy 8. No screen cover but no company I've found has a good screen cover for the damn edge to edge display . And it was only $16.00 direct from Magpul.
I went with the UTG AR fixed rifle stock (also clean and uncluttered looking) instead of the Magpul for my .450 Bushmaster build. I just could justify $80 versus $38 for virtually the same thing.
