Where are these had in Canada? I'm toying with the idea of getting a second one, and I'm looking at something with a 1:12 twist
 
1:12, good luck. You're looking for a surplus M16 upper or an SP1. Most modern (A2 and up) uppers are 1/7 or 1/9, with a few 1/8 kicking around.
 
Seems to me, a 1/12 twist would do much better with lighter weight bullets. But really, I'm still just toying around with ideas, I'm not actually set on buying one
 
Your best bet would be to pick up a good, used Colt SP1 on the EE. You can sometimes get a deal on one that is only a couple hundred more than buying just a factory upper. They don't sell well in this age of the 'tacticool' so owners looking to sell usually are a little more flexible on pricing.

I think Sean at Freedom Ventures was going to be carrying STI Uppers and Lowers. Not sure if that has come to fruition or not, but he did mention it a while ago when I inquired about getting another Upper for my STI!

Catalog says in August....actually, I'm pretty close to just flat out buying the STI AR....so many benefits in both the upper and lower halves, especially at that price point.

Have you fielded yours yet with a scope? I was curious as to what kind of accuracy they are getting.

I've read two reviews from gun magazines, one mentioned average sub MOA results with 69 gr sierra matchkings, with the smallest group being 0.5 MOA
 
With the 1-4 Millet that I have on there now, I was getting 1 1/2" - 1/14" with AE FMJ, and under an 1" with my lightly loaded 60 grain Vmax reloads.

The gun is a dream to shoot with the Compensator and Trigger that it ships with. In hindsight, I would rather have the Competition upper, rather than the tactical one that I have. Once Sean gets the uppers in stock, I will likely buy the Competition upper, mount the scope on it for USA excursions, and use the tactical one for Canada IPSC and multigun stuff!
 
You really think the competition model would make that much of a difference? STI says it adds stability, but it only extends the HG by 1-2"

Having the flexibility of mounting a front sight seemed more preferential to me
 
I find the hand guard too short! My thumb gets on the gas block, and gets burnt! It probably has to do with the way I grip the front end obviously, and a forward grip might solve some of this, but that is just my observation and shooting style!

And really, how often has it happened that a scope fails, and you complete the rest of the competition with Iron Sights? Pretty slim chance.....I mean, it is nice to have a back up plan, and if my life depended on it...that's one thing....BUT......
 
I like to shoot both irons and scope but don't want to buy two uppers, too expensive...I usually grip the gun at the mag well, but am considering one of those slanted vertical grips too

Its my presumption that a 1:12 twist would be better suited to a 55gr round at say 200 yards.

A 12 twist is certainly designed around the shorter, lighter bullets.
However, if you are not planning on going anything under 55 or similar in size/weight pretty much every currently available twist out there will shoot them just fine - 9s, 8s and even 7s...with the benefit of being able to stabilize longer/heavier bullets too (up to a point depending on the twist you choose).

I agree with X-man regarding the SP1 being one of the best bets for sourcing a 1:12...but then again, unless you are after the nostalgia the SP1 offers, I wouldn't bother.
 
1/9 handles 55gn quite nicely, 62gn as well. If you were wanting to shoot 40gn then I could see going with the slower twist.

Still, if you're on a budget and looking to get into AR's then 1/12 is still a good route like others have pointed out. I picked up an M16A1 clone for $900 simply because they're less desirable to the tacticool crowd. If you don't plan on accesorizing, something similar (SP1) would serve you well.
 
My 1/7" AR shoots 52 gr SMK's like gang busters.

Only worry about twist rate for heavy bullets.

Worrying about slowing the twist rate to optimize shorter lighter bullets is "overthinking" it in a big way.
