So here's a dumb series of questions for everyone. Again, realize that I'm a complete noob/idiot. Anyway... What's the big deal about AR-15s? Why does everyone talk about building them, as opposed to buying them? What's the lasting appeal of these guns? I'm not questioning/challenging it - I'm just trying to understand. Oh and here's the biggest question: not counting 22lr (simply because I've never, ever, ever even seen the ammo in any store, even price-gouging shooting ranges), what's the cheapest *realistic* AR-15 configuration to operate?
I guess I didn't mention that I got a hell of a deal on a brand new Mossberg 500. I paid less than what a Maverick 88 sells for. So now that puts me at owning a handgun and a shotgun. A rifle is missing...
Heres what i see as pros to the AR-15 platform
-Super customizable. You can pick whatever stock you want, foreend you want, grip you want, ect. it all just stems from a universal lower (ie a AR-15 lower will work with any AR-15 parts).
-Can be done cheap (M&P Sport or a PSA offering for ~500 bucks or so) to super expensive (ie a JP, Larue, JP, ect).
-Even cheap rifles these days tend to be good shooters. My PSA which i built for ~700 bucks (PSA premium upper) shoots MOA which is pretty good.
-One lower can service any AR-15 type upper (300blk, 762x39, 5.45x45, 6.8grendle, ect....just need different bolts/mags for some.
As for build vs buying....
You can build an AR with tools found around the house. Well the lower at least...uppers take a bit more (torque wrench, armorers tool, and vice block). So you can generally piece together a AR of high quality parts for cheaper than buying a factory model with the parts you want. If you are just going for cheap though then it is hard to beat the newer offerings there (mp sport for example). By building you also get exactly what you want right out of the gate instead of upgrading things.
As for the "cheapest to operate"....really you are looking at 556/223 or 762x39. but both cost about the same these days so i would still go with the 556/223 as it is way more common so be easier to source parts for at a LGS type place.
on another note i picked up a dillon 550b. Got it setup minus the priming portion and loaded up some 223 i had preprimed. Now just to get the priming setup and ill be gtg!
