Hi thanks for the reply , the problem with the newer models are the knibs on the edge of the mag they stop the mag engaging they appear to be a different height ,I had a dealer get one from Edgars  and they suggested dropping the trigger guard and shimming  , they adjusted the trigger guard but it thru the mag out of sync and still would not engage ,all they kept saying it's a old gun? Dom @ riflemags said put the mag in a vice and squeeze to compress the knibs .On the later mags they are stamped .223 Rem with mine no markings but they look similar until trying them, I will try and measure , thanks Mel.
