If you ask me Mac tools are the best.
Craftsmen are still ok, But I've noticed quality dropping.
What seems to break on me more then anything is ratchets, Seems like the replacement is always cheaper looking then the one I brought in.
Last craftsmen I took in was a 3/4 drive, It was pretty old back when the whole thing was chrome including the selector switch.. sad to see it go but it was slipping so I had no choice.
I don't know about Torque wrenches, I need one my self for AR builds.
They can get very expensive for name brand.
HF sales Pittsburgh tools, these actually have a life time warranty.
Honestly? in general for the money they're not that bad, finish is surprisingly good on them for being so cheap, I do think their metal is more on the brittle side though.
The 1/2 drive

Seems to have fairly decent reviews. It says accuracy is +- 4%
That should be good enough for AR15 especially if you shoot for the middle of the torque range.
@ 55lb torque, you'd only be looking at say a 2 1/4lb shift.
The real question is how long will it retain it's calibration?
Torque wrenches sometimes need re-calibrated, especially if they're dropped.. always store them in a case and put them in a place they wont be banged around.
So I Guess you gotta ask your self, Do you just need one for AR work? or do you also wanna use it for something else like automotive? light vs heavy use.
If heavy use then probably something better.
On the other hand..
These HF torque wrenches are cheap enough you could probably get one just for AR work.
They're listed as 20 on HF and they've got 25% coupon for the 4th.. so walk out with 15+tax.
That's probably what I'll do.
