    That cheap russian Bear crap should be limited to soviet style weapons, it works on some ARs, but its just nasty stuff.

    I've used the AA piston kit on several builds for customers and have not had anyone complain about them malfunctioning. Even after running several hundred, and in one case several thousand, rounds of cheap ammunition.

    I've installed them on:

    5.56/.223 uppers

    5.45x39 uppers

    6.8 SPCII uppers

    6.5 Grendel uppers

    No problems with any of them.

    I gave A/A a call and they stated that their complete upper piston system has zero issues using cheap steel cased as they ensure proper port size and gas block alignment, all I have to add is a standard buffer and spring in my Mil-Spec lower.

    A/A also stated that the piston is self cleaning and only requires being wiped down every thousand rounds.

    I will see if they speak the truth once I get to the range and fire a few hundred rounds.

    In what condition did your AA upper arrive?

    The AA I ordered from Midway arrived damage as Midway did a total crap job packing the upper. This will be going back on Midways dime and it will be the last item I ever buy from them.

    All too often there are instances of this popping up with midway. Somebody needs to tell that old dopey bastard Larry Potterfield to get his shit together. I'm not even gonna take the chance ordering something like an upper from them, though I had considered it. I don't think they care about the customer, they claim to. They just want their money and for you to contribute to their NRA "roundup".

    Sorry to hear about your shipment, mine came ok, but it had no user manual or paperwork at all.

    Same here,

    It appears that they removed some foam padding to stuff one of there catalogs inside allowing the upper to bounce around inside. My unit has a few dings Thur the finish on the left side of the receiver.

    Cheap steel cased ammo (wolf, bear) is not corrosive like the old surplus ammo. Completely different animal. The steel case ammo is just a little rough with the extractor and inaccurate.

    I don't think "inaccurate" is quite the word to use.. inconsistent certainly describes them though.

    Just as a lark a friend of mine and I chronoed a bunch of different steel cased ammo from the "W" and "T" people.

    As much as 400 fps differnence within the SAME box of ammo!

    Shades of golden bullet!

    ( and yes that inconsistency in loads contributes to crappy accuracy.)
