Actually most of them are made from the same specs, more to the point, the same parts with different roll marks. Not that they are all alike. QC and certain critical parts may be of better materials and quality, like bolts, extractors and barrels.
Mil spec ARs are made to better and stricter standards and use better materials throughout.
They are in no way the same as cheapo cost cutters and if you are going to use it a lot these differences in most cases become quite transparent.
Remember the AR platform started out as an A+ certified POS (junk) that is directly responsible for deaths of a lot of soldiers, no question ifs ands or buts ,it's a fact.
Everything done to that weapon to make it Mil Spec was for a reason that was learned the hard way to make it a decent or perhaps more than decent firearm (it's ergonomics was always second to none and probably what redeemed it) for it's intended purpose.
Don't step backwards and reinvent the wheel when it comes to the AR platform. They have to be done right.
Right now I'm looking at the RUGER AR 556 and the SMITH & WESSON M&P.
Buy whatever has the roll mark you like.. that's about the difference in most of them.
The thing is, the bcg, barrel and receivers you'll most likely never change..
Colt makes the best.
"Colt makes the best."
Actually, no, I don't think they do. And the organization has been in and out of financial troubles for decades.
Several mfrs. make a better product than Colt; some for less money. Nevertheless, in the AR world, Colt has an excellent resale to purchase price ratio. Doesn't hurt that they will celebrate their 160th birthday this year.
I wouldn't recommend a Carbon 15, but if you go that route, be aware that some parts are different than what most of us call 'mil-spec'.
"With today's pricing I don't think anybody makes an objectively better rifle [than Colt] for less. The closest that comes to mind is Spikes Tactical for a little less and the only way it would be 'better' is the mid length gas system."
Well, then...we are in agreement in general...but disagree on the number of "better" ARs for the money. Opinions do count no matter how they are formed.
"Better" is relative. Most of us won't have our lives depend on them in the mountains of Afghanistan. all of my current ARs are Frankensteins. However I have top of the line parts in them. Well I guess my 6.8 is a full cmmg production rifle. You can say whatever makes you feel good but I have 2k plus Frankensteins that will out shoot any colt you can come up with. I have two in particular that are sub 1/2 moa guns. Now they were expensive to build. But if your not looking for that kind of accuracy, Than my cmmg is reliable as they get. every bushy I've ever had ran great. People love to hate bushy. Truth is they run. Without selling your first born to get one. Decide what's important, and go for it
