JohnnyK didn't ask "what's the best deal on a rifle?" he asked "what's the best deal on an AR?" That's not like asking what's the best deal on a car, or a VW- that's like asking what's the best deal on a Mustang
Yes but it is far from ideal.
The Colt 6920 is the ubiquitous suggestion that is always thrown out that really isn't that great of a rifle.
The 6920 is a great choice
Lots of good ways to go. With an AR, a lot depends on what the round count will be over the life of the rifle and how much you plan on shooting it from the bench. This will matter because some ARs will last much longer than others when shot a lot, and there are some very accurate ARs that weight a whole lot, as well as some fairly accurate ARs that are light and handy.
This is where the conversation goes sideways
Just to put this in perspective, does anyone recommend any 16" barreled, non-free float, 1.5 moa capable, 5-8 lbs trigger rifle for hunting p-dogs other than the Colt M4? What? No one? That's not even close to what's ideal? Perspective...
Here is where we throw in a big strawman argument. What does recommending a non-Colt AR in this configuration have to do with anything? It doesn't.
For those who wish to skip right to the point, this question is asked a thousand times a day. 99 times out of 100, the right answer is a 16 inch carbine.
How This Thread Went Sideways
Folks who want to be helpful or show how clever they are or just want to show how much more they know than the new guy toss out the "well, it depends on whatcha wanna do with". Actually, it doesn't Most anything you want an AR to do can be down with a 16 inch carbine.
I've come to realize that no matter what accessories you throw on an AR, there really is only about three different types before adding optics- Rifle length barrels, carbine length barrels and SBR length barrels and the 16 inch carbine will do most things the rife & SBR will. The sights determine how a rifle will be used more than anything else.
You don't think so? Then answer this- What is better for p-dog shooting- a 20 inch rifle with a free float tube, G trigger and open sights, or a 16 inch carbine with round handguards, standard trigger and a 6-24x variable?
Certainly, it would be better to put that variable on that 20 inch rifle, but the point is that the sight determines what a rifle is suitable for, not barrel length, not handguard type and not trigger. All this "It depends on how you'll use your rifle" gabble just confuses the issue
What do you think would give a new AR shooter more satisfaction- agonizing over what accessories they should have on their $2k AR that will take 6 months to fund, or an $800 6920 they have in hand in a month or two and will add accessories as they go along because they found out by shooting their rifle which accessories actually match how they use the rifle?
Why a Colt 6920 is a Great Choice
Prices on Colt 6920s i lower than they have been for many years and they are easily available. Colts are well made and you can count on them working right out of the box. It's a basic carbine and while it's configuration isn't ideal for everyone, I'd much rather add a free float tube to an $850 carbine than get stuck with a handguard I don't like on a $1400 carbine.
If the shooter decides, after sending a few rounds downrange, they've out grown the 6920 it will be eaiser to recoup their investment. During times when ARs are scarce and hard to come by, Colt price go up before any of the other brands.
Bottom line: When someone asks "What's the best deal for an AR" it's much easier to tell them to go get a Colt 6920 rather then try to educate them on their choices. This question comes up a thousand times a day on the internet and if the poster was really interested in a more informed answer, they'd do their own research and come up with the answer for themselves.
That's why saying more than "Get a 6920" is a waste of time
