Don't you remember Charles Schumer SCREAMING on Capital Hill about how easy it was to turn a semi-auto AR15 into a full-auto M16?
Colt detractors would say that Colt took the PC approach, bent over, and changed their design. I'd say that Colt saw the writing on the wall and did what they had to do to take that rhetoric away from the antis. And guess what? A few years later we're worse off anyway, except that the antis still can make the kitchen table machine gun argument because the cloners still use small pins...
But is 1/7 the way to go? How many people really want a barrel that requires them to use heavier, more expensive, bullets? I don't remember hearing of a single person who has asked a dealer for a 1/7 rifle lately
You're kidding right? Are you a dealer? With a 1/7 ROT barrel you aren't required to use heavier bullets, so your entire premise is bogus. With a 1/7 ROT barrel you can stabilize anything, from lightweight varmint rounds to heavy OTM rounds. That's the beauty of 1/7, you're not limited AT ALL...
As far as demand goes, apparently you missed these threads:
AR15.com forumites BEG Bushmaster for a 1/7 ROT barrel
AR15.com poll for Bushy 1/7 ROT barrel
I do recall political heat as being probably one of the reasons Colt--sometime in the early 90's--went to large fire control pins. It was probably a good decision at that time, since much of Colt's income came from govt contracts and they no doubt felt threatened, but I notice nobody else changed.
But since Colt is now unfortunately not the large volume AR15 maker it was then, and everyone else uses small pins, I do not understand why there hasn't been an attempt to change back to the original size.
It clearly would help sales, reduce production costs, and simplify parts and service issues.
If ATF is really blocking that move, it's hard to believe that some of us wouldn't know about it. Shouldn't every other maker be subject to the same restriction? As you said, the cloners still use small pins, and you can buy 3 and 4 position conversion kits all over the place.
Maybe since Colt is still a military contractor that might have something to do with it but, if it is, it would help them to get the word out somehow.
On the 1/7 issue:
I don't want us to depart from the thread into just one or two items, but would like to respond with what I know, or think I know at least.
A 1/7 will shoot anything? Not for me.
I'm not a ballistic expert but have been unable to get my COLT 1/7 HBAR non-chrome-bore to group light bullets properly--with either my loads or any factory load I have tried. And that includes some loads that will go well under MOA all day long in a 1/12 barrel (as you know, the original M16/AR15 ROT for 55gr). It does well with 75 & 77 gr but nothing else. If someone has a 55 or 52 grain load that will do so, please share it with me.
Demand for 1/7?
I had missed those two threads. I read them. I don't see anybody wanting a 1/7 to shoot light bullets, only heavier (much more expensive) bullets. And that's a valid need.
The poll shows, if I remember correctly, 69% of 226 people want one. And they seem to be serious shooters, not the average gun buyer, or the person who is limited to short range shooting.
I don't see 1/7 barrels for sale in any quantity at gun shows, and those I do see just lay there, they do not sell quickly.
I do see people trading 1/7 uppers for 1/9's.
I don't see them for sale in gun shops very often, and dealers tell me most people don't want a 1/7 if they just want to plink or shoot in quantity (which is most AR shooters).
I don't see Bushmaster (or OLY etc) rushing to produce them, and they're pretty good at reading the market.
So if there's a case for a 1/7 being the barrel I would produce in quantity, I don't see it yet.
A few, sure, but not a large % of production.
