It took me a couple of tries, and I have one nasty looking castle nut on the end of my stock now, but I got my carbine buffer tube on straight finally.

Is there any trick to this or is it just hit or miss?

I am not clear what you are asking... Are you finishing an 80% lower?

It will only go on straight. Otherwise the plate wouldn't line up with the receiver.

Does he mean oriented correctly in the vertical plane ? The plate that fits between the castle nut and the lower receiver is supposed to do this, but there is still some play. I just eyeball it and get on with my life... its not critical, so long as it feels OK to you.

Exactly what I though when I read the concern.

I believe that he's asking, when you drill & tap the hole for the buffer tube, how do you get it straight? I assume that he means parallel to the top plane of the lower.

But you don't often get several tries.... I am still confused...

Were you cross-threading your buffer tube? Just go slow. If necessary, I think youcould pull your bolt carrier out through the back to encourage proper alignment.

Oh man...

I created a mess.

when tightening the buffer tubes castle nut, my buffer tube rotates clockwise with the castle nut.

Just talking about regular plain old collapsable stock installation onto a bushmaster lower.

I think I have a very loose plate then...because I can get mine to rotate pretty far.

This should not be possible if you have the backing plate that fits between the lower receiver and the castle nut properly installed on the tube.

Actualy i have seen pretty shodey backing plates in the past. The larg machine divit in the bottom of the plate is supposed to be just about the same size as the hole machined into the back of the lower for it to lock into. i ran accross a cheap stock that had a plate and the divit that is pressed into the plate was actualy undersized in diameter. The stock would indeed turn a good 1/8" or 3/16th of an inch when tightening the castle nut. Id recomened buying a new set of hardware from someone like MSTN> He sells the LMT nut and plate for 15.00 range and they fit perfect.

Well shit, I'm just gonna get quality stuff...

Goin LMT Ribbed style collapsable stock and hardware...

Didn't want to spend the money, but what the hell, my M4 is worth it.

Where did you get the stock you are using... I have a guess but I want you to share before I guess!

Now, do you have pics? I still think you must be doing something wrong here!

its the 7 position stock that was on the board about 3 months ago.

Hmmmm I really would like to see the pics now

Adco was selling them...

do you really want to see some pictures of it or are you just being sarcastic :-)

I can take a few and email them to you if you like.
Link Posted: 9/4/2004 9:35:04 AM EST
I was being sarcastic... my point was these must really be junk to have the problems you describe... OR.. you really did something wrong....
Link Posted: 9/4/2004 9:39:44 AM EST
just checked everything over...did nothing wrong. The tilting isn't that bad, its just enough to where I notice it! It could also be due to the fact that I really have a think for tightening castle nuts down pretty good. Probably alot tighter than they need to be.

are you talking about "timing" the buffer tube? If so I don't think it's necessary.

It's necessary for a carbine buffer tube, but the back of the lower receiver and the castle nut backing plate are supposed to take care of all of that for you. In this case, I guess it doesn't. Mind telling us what brand of lower receiver you are using.
