Help in Tucson with Buffer tube
I have a weird "request" or "situation. Long story short I moved a few months back and in the process I can't find my dang lower receiver block and I ended up dropping my vice and cracking it in half during the move. No biggie, I'm mostly buying Sionics gutless lowers anymore as they do the work for me except for things I WANT to customize and install (fcg, furniture etc). Now, here's the rub. I have an Aero lower that I installed a PSA lpk in some time back (it's just used in conjunction with a CMMG 22lr bolt as a plinking rifle for my wife). Now, on this particular lower I had accidentally canted the buffer tube when installing slighly (it was my one of my first lowers about 2 years ago when I wasn't as careful as I am now) and it's been bugging me, so I said to myself "hey, I'll just break the staking on this, realign, and then re torque down, easy fix". So I grab my trusty magpul wrench, break the staking and get ready to go put it in my vice to re-assemble when it clicks in my head "wait, I BROKE my vice 2 months ago!!!!" and without 3 arms it's REALLY hard to get the buffer tube 100% timed straight without a 3rd arm or the use of a vice and block to make sure it doesn't rotate under torque. So now I'm stuck with a lower and buffer tube assembly that's not put together and I'm out the proper tools to hold it in place so I can install properly besides my magpul wrench and me cussing at myself for forgetting
what I was HOPING, was that a Tucson area M4carbine member with the vice and block would be kind enough to give me a hand reinstalling the buffer tube (had to go order a new back plate and castle nut as I don't like re-using them) PROPERLY, as I'm currently in between vices (and I can't find that dang bev block, it got lost somewhere in the move). I'd be happy to bring the beer or take em out to lunch as thanks for giving me a hand tightening it down properly

You don’t need a vice.
You can do it with your bare hands honestly and just torque it with a wrench then stake it.
And what to you mean you aren’t getting it timed? You rear end plate does that for you. You don’t have to time it. The buffer tube and end plate work to go to always get it perfectly timed.
Go to any shop and I’m willing to bet most will do it for you for free.
Diamondback if you on the east side, 2nd amendment for central ask for Steve C, Disruptive Products on the west side ask for Larry.
Or just call Sionics on Monday and I bet Steve-O will help you out.

There is supposed to be some play in this arrangement until the castle nut goes on. The castle nut is what holds the end plate and buffer tube in place.
