    Well, at least I am not the only one. I was worried that I had just cross threaded it or something and messed it up myself.

    I don't know how long this will take, but I'm stockless until then I guess. Not much I can do about it at this point, and I already tore the threads on the receiver extension up trying to make the other one fit.

    Normally, when things don't feel right like that I'll back off ... but I read several threads saying that the fit was always pretty snug, so I figured I'd keep on trying.

    mmike87,
    I asked you to send us the tube and screw to see what the problem might be. We manufacture the stocks. The tubes and screws are outsourced. We assemble the stocks before they go out. I am going to assume that your stock arrived assembled and not in pieces? The assembly process we do is put the tube inside of the stock, put the standard buttplate and sling mount into place, then both screws are put into place and tightened to hold the buttplate to the stock, and finally we put the buffer and recoil spring together and place them inside of the tube. If the threads were not working we probably wouldn't be able to get the buttplate screwed onto the stock during assembly before packaging and shipping. Most of the screws that we use for the tubes are the standard A2 screw that most times comes with Nylok on them, occasionally the supplier sends ones without the Nylok. The Nylok will make things tight, as it is designed to keep the screw from walking loose. The top hole in the buttplate is canted at a 4-degree angle, Milspec design from the A2, which adds tension to by pulling the buttplate and stock. It is possible to cross threaded things trying to put the top screw (A2) in straight and not aware that it is canted. When installing the buttplates it is best to slowly tighten the screws together so they pull in evenly. Anyways we are awaiting your tube and screw to figure out what the problem is, it could be problems with the parts or the assembly, we will deal with it when it arrives. If you wish you can send us the lower receiver and we will happily assemble it for you if you wish.

    It's in the mail tomorrow. Like I stated before, I tried to thread the screw into the tube BEFORE I even assembled to stock. It was very, very tight - but I couldn't get a lot of torque on it holding it in my hand. Some posters on TOS suggested in the past that it was often a tight fit, so I assembled the stock and observed the same tightness.

    Yes, it arrived just as you said. And the screw threaded into the stock just fine, just not into the tube. However if it's necessary for the screw to actually thread into the stock, then those threads are stripped now. I figured what really held it all together was the threading into the tube.

    I understand what you say about the canting, but it did this with the tube outside the stock as well.

    I thought it was just that I had done something, but the other poster in this thread observed the same behavior and solved it using a different screw.

    Regardless, thanks for the explanation and the tube and screw are already boxed up and will go priority mail first thing in the AM.

    Thanks.

    Fine customer service for me would've been...

    1. Send the customer an immediate replacement for the parts, next day air.
    2. Send a return mailer envelope so that the customer and can give back the poorly spec'd parts.

    The bright side is I like the way my Sully stock feels on my BCM build. I still think it's a great design. My confidence has definitely been shaken though until they can get a better manufacturer for their out sourced parts.

    Update.

    I received a replacement tube and screw, and they all fit perfectly. The stock went right together and I had no issues. I like the feel of it ... it's very solid and has a good cheek weld. I'm using the extra spacer.

    Included: A t-shirt and a $5 bill to cover the shipping. That was a nice touch and appreciated.

    Two questions:

    1) Should I use blue locktite on the tube and screws, since the tube can't be staked?
    2) What torque do I tighten the stock screw down to? I snugged it down good with the screwdriver, being careful not to overtighten. I googled "AR 15 rifle stock screw torque" and some other variations and nothing jumped out at me.

    Now I just need to snag the Tango down QD sling adapter that hopefully will fit around the base of the stock.

    Thanks.

    The Sully is awesome - my only complaint is their screws - mine are chewed up after a few takedowns. Other than that, it's a beautiful stock - cheek weld is superb. I too use the spacer and the fit is just a hair off, but nothing to get anal about. I found no need for LocTite whatsoever, nor measuring torque. I snugged the tube up with a wrench, slid the stock on and snugged up the stock screws - it's rock solid. I officially hit 1,000 rounds with it this afternoon, (man was it freezing) and I like the Sully more with every pull of the trigger. I need to install my Sully Trigger Guard next....

    How is the Sully stock working for you?
