    I bought a USR from a gun show without a manual. I've got 1k through the gun and would love to clean out the carrier tubes and springs. Does anyone know if the end caps are threaded "right to tight"? Any advice on doing this? Many thanks.

    I assume you are talking about removing springs from the gun lock group...unfortunately it is a sealed system - so i dont know why you need/want to clean it.

    In order to remove it you would need to heat up connection point to 250 degrees celsius in order to break Loctite bonding compound. In addition you would need to clean areas on lock group and trichloroethene is recommended for this but it is as toxic as hell!

    I purchased my USR at a gun show about two months ago. Five 30 round mags, and one 10 round. It came with the original box. Was suposed to be new in box. That night I dismantled it and inspected. Since I was not too familiar with this rifle, I didn't know what to look for. The gas piston was bright and shiney. No marks behind the ejection port on the stock. No marks on the hammer. Took her to the range with my lovely wife, who wasn't real happy with me spending $2700 for a new gun, as I bought a PS90 in January. That was supposed to be my "one gun for the year." After firing 80 rounds, took the rifle home and cleaned it. Could not fully remove the slight charring on the gas piston. It also had some slight semicircular marks behind the ejection port opening on the stock. "Put some velcro stick on stuff there." That solved the problem. I like the USR more than the AUG because it does have the different bolt carrier with the roller on top, and especially because it has the bull barrel. My match AR15 has a bull barrel, and it is supposed to give greater accuracy.

    Glad to hear you like it.
    I think your referring to the fact that the few AUGs imported to the US have the older model carrier, well, because they are older model?
    For example my A2 has the roller on the carrier.

    BTW is it quite common that the brass hits the stock, leaving marks?
    I noticed that on my rifle, too. I guess I should tape it...

    The marks left on the stock from the ejection of the spent brass are normal.

    While not a concern for the soldier, it would be for me if I spent over two grand for a rifle (I can remember when an A1 AUG was $570.00). It would be a good idea to use some form of padding behind the ejection port. I use four layers of duct tape one on top of the other. It makes a good pad and can be removed, and replaced easily.

    I wish I would have knowen the SIG 550 did the same thing before I put the first forty rounds down range. :x

    UziGeo, your story is almost the same as mine.. Came home and suprized the wife with a USR one day myself.. I bought mine "as new" as well, but I don't think that is the case.. It came with the optional mounting rail and also a Beta Mag...

    Any one have any ideas of what would make a good scope/ optic ?
