Brownell's 20" A1 Profile Barrels

I still want a 1/7 twist and an F marked FSB.

[#2]

Should be popular with the light weight build crowd as well.

The intro was too long, and I felt that the A1 profile barrel did not get any screen time. One out of five stars.

Went over the barrel specs quickly.

I noticed that he didn't mention a twist rate. Any guesses what the A1 profiles twist rate will be?

Brownells stopped by a while back to get some feedback, they said it will be a 1 /12 twist with a rifle extension. Markings will be under the handguard.

Wow. I'm surprised about that in two ways. I figured it would have been 1/7 and would come with M4 ramps.

Can't wait to see if they come with a fsb too and what price tag they'll put on them.

The barrels are 20" A1 profile with a mounted FSB and 1/12 twist. They couldn't get stamping done out front, so it will instead have the markings laser engraved on the side of the barrel under the handguards so a to be discrete.

I also believe they are chrome lined.

Info per Paul Levy at Brownells when I met with him on Thursday about our product line that they carry- we both have a soft spot for retro AR stuff.

I'm holding out for the 1/7. Really, what's with all this 1/9 crap??

Brilliant!

I'm not surprised that someone eventually would step into this 'niche' market.

With all the tacticool and 3 gun bases already covered by other manufacturers and vendors

they're offering something that doesn't compete with those suppliers and has a built in customer base.

It'd be great to be able to get all my repro-retro stuff in one place.

Wanted a lightweight 20 1/7 or even 1/9. Already have a 20 1/12. Love the weight, but don't like being stuck with 55 grain ammo.

I would hope someone would step up to the 1/14 plate :)
That said the realistic best twist rate is 1/9 or 1/8.5 for most of us.

This obsession with 1/7 as the 'milspec' is silly imho. how often do you really shoot
77gr MK262 out of a retro gun? I'd wager never.

Often enough that I'll never own a 1/9

If you want 1/7, buy the McKay offering and be done with it. I'm ecstatic about the 1/12 clone of the originals.

I should get one and make a 22LR plinker.

1/7 is still more versatile than 1/9. Buddy of mine used to shoot everything from 45gr varmint loads to M855/SS109 clones from his 1/7, even dabbled with some 75gr BTHP once in a while.

If you're going to go with the non-original twist, IMO, better to go with the one that lets you use ALL the options available in 5.56mm. Why limit yourself, once you've made that jump?

ETA: Also, why 1/14? There's a reason the Army ditched that twist rate: it didn't even reliably stabilize 55gr M193 in colder weather. Unless you're shooting nothing but 45gr varmint loads or .22lr subcaliber, almost any other (read: faster) twist rate is going to be a much better option.

This is the retro forum. We have a sickness for out of date stuff.

The only reason why 1/14 was on the original guns was because the common rate of twist at the time in center-fire rated .224" barrels was 1/14 for the .222 Remington.

The AR15 was engineered/drafted around the .222 Remington, and the first prototypes were originally chambered in .222 Remington until they transitioned to the .222 Remington Special/aka 5.56x45.

Stoner never designed the gun to have a loose twist. That's just the twist rate that was available at the time. This is all discussed at length in The Black Rifle, Volume I.

The military went away from 1/14 because it didn't offer adequate spin stability in cold weather as the distance increased, so 1/12 was adopted during the production of the Colt 602's IIRC. Somebody correct me if I'm off there, but that seemed to be the best we could figure last time this came up.
