Picked up a standard Mini 14 197 prefix with nice dark looking wood stock and the older type mini rear sights looked unfired no box 550 . Would this one have the latest and greatest updates compared to my old G/B models like bolt ,slide ,extractor type things ??????? I had a Colt M4 in my hand and also the Ruger PR rifle that looks like a AR . I don't need any more AR just sold a older L/E marked one last week. I just kept going over to this nice standard Mini 14 like back to my younger days . I had them in 1975 and up . How are these .
