WTB - AR15 with 1x7 twist barrel

[45Carrier]

I am looking for an AR with a 1x7 twist barrel. 16" preferred.

Please PM details with pic and price if you have one available of know where I might find an AR at a reasonable price.

New preferred, but used is fine if price reflects it being used.

I just got a nice fat box of 77gr SMK's for Christmas and I want to shoot them through an AR ;)

At a "reasonable" price?

I recall thinking the prices looked very reasonable when I glanced a the AR shelf this past Saturday. There were a lot of AR boxes going out the door so I have no idea if any are left. However, I was at the store near quitting time and the store was closed on Monday.

Reasonable is in context with just how bad someone wants something of limited supply. Saw a couple sites with ammo "in stock" and some were charging $600/1000 of 5.56. Many who are buying the AR's now are getting an expensive club.

I have an inside source with Wally World that told me they are still getting ARs almost daily in many locations. They are just selling out very quickly. I saw a post on another forum that said Walmart pulled ARs from their shelves which is not accurate. They only removed the listing from their website which was not an impact because they don't sell guns on their website.

So keep checking with your local Wally Worlds.

They have barrels in the $100-150 range new that's about the best you will find especially currently

I'm curious. Why does the twist matter? Is there a big difference between 1x7, 1x8 and 1x9?

My question exactly! I see it all the time but don't understand the importance.

1/9 twist will allow you to shoot bullets up to 69 grains accurately. Get a 1/7 if you are planning to shoot 77s or 80s. 77s and 80s are generally only used for target shooting, most plinkers shoot 55 and 62 grain military type ammo. I used to shoot competitively and used 69s for up to 300 yards, and 80 grain bullets for 600 yards. If you try to shoot bullets too heavy for your barrel twist, they will not stabilize and fly sideways, causing a "keyhole" and crummy accuracy.

Ditto with bullets that are too light. For instance, none of the three 1:9 barrels I've owned would shoot a 45 grain bullet worth a cup of warm spit. But they all shot 55-69 grain bullets just fine. That said, 1:7 barrels will shoot 55 and 62 grain bullets just fine.

Well, since the can of worms has been opened, its actually about the LENGTH of the projectile, not its weight specifically. It just so happens that as you make a bullet longer, it tends to be heavier. The tighter the twist, the longer a bullet that can be stabilized (and thus, generally, the heavier a bullet, too). There is an actual formula for it, but I'm not a ballistics guy or a math wiz. You can do a search online and find it pretty easy, though.

If you want to get real nit-picky, it is NOT about the overall length, but the "bearing" length, that is, the length of the bullet that actually engages the rifling. So since the bearing lengths are different, a .308 220 FMJ will not stabilize out of a 10 twist barrel, while a .308 220 30-30 (round nose) bullet will. Essentially everyone who shoots .223 competitively uses Sierra Matchking 69, 77 and 80 grain bullets.
