I have searched but I can not get any info on these, this one I'm looking at has a 1:12 twist 11.5" CAR type barrel.  I was wanting to know are these recievers cast or forged, are they desirable and what kind of price range should they be in.

You must be talking about the title II sendra on Sturm.  By the time you find out about it, it will be gone.  Sendra has something to do with NESARD (same letters) which I believe is the  Model 1 sales folks now.  I could be wrong, but it is one of the 2nd tier manufacturers.

No this one is in a local shop, I just wanted to get some specifics about it if anyone was familiar with this AR.

Old ones where ok lowers. Most I saw had  a bad finish on them. Some here VERY purple. The only problem I have seen was that the buffer detent pin hole was misplaced on one I had and the buffer gets beat to death by the pin because the carrier does not push the buffer off the pin when you close the upper. Easy to see if it is doing it on a used gun because the edge of the buffer has dents all the way around the edge.
There was some newer (newer meaning when they were sold not made) ones during the ban that have a circle on one side of the mag well.

I've had my Sendra lower AR for 23 years, never a problem with it.  Not exactly the best finish, but it works every time.

good info, thanks
