Which upper would you get? I'm primarily interested in something for HD that I'd shoot supers and subs, but neither with a can. I haven't fully decided between 8.5" and 10.5". I like the compactness of the 8.5, but would go 10.5" if there's a large impact on accuracy. Velocity should only be about 100fps, so nothing crazy advantageous between the two. With 1/8 barrels, I don't know if the 10.5 would help better stabilize heavier projectiles or not. I also don't know if a 10.5 would be more likely to be overgassed due to more dwell time, or if it would be more forgiving across a wide variety of ammo choices. Help
PSA 8.5" upper-
It's cheap, with a bcg and ch included. Drawbacks are a long wait till they finally ship the derned thing,1/8 twist instead of 1/7, and the handguard is shorter than the others. I probably also prefer a linear muzzle device to keep noise away. I haven't really found accuracy data on them except people's generic "shoots well", but am leary of going 8.5 instead of 10.5 due to the 1/8 twist. I don't have plans to toss a can on anytime soon.

Mas defense 8.5" with linear comp-
it's more expensive by about $150 than the PSA, but it has the longer handguard and muzzle device I'm interested in. It also has 1/7 twist, with the option of a "match" barrel upgrade. It seems like this shouuuuuld shoot better, especially with subs, because of that. I don't really see a lot of reviews giving hard data on performance. They don't seem to have as big a track record as PSA, but seem to have better customer service if something does go wrong. I'm leary that they give two options for what the bolt steel in their bcgs could be.

Hardened arms-
They're more expensive than PSA, but still only 1/8 twist, and the handguard options I like come with a brake that I don't. They seem to have a decent reputation though, so I figured I'd toss emm in here

Radical firearms-
This one is promising. It's PSA cheap, but with 1/7 twist. The rail on it is shorter than I'd like though. With a linear comp, I'd like something more like a 9" mlok rail for mounting a light out further.

SOooo...which one out of these cheapies is where you'd go? Or would you just do something different/build your own? With the price of the PSA and radical, it almost doesn't make that much sense to piece one together for more loot.
