Plastic guns hehe I am not enpressed, in all the new guns. I do not have any mark5s nor have I.I do have older 77s and 700 and allso some savages.I am looking for a high gloss wood gun ,they cost a ton more than the plastic guns of any brand.
I beleave that you can get a good gun any any brand and to say one brand is junk is nuts.

MY best gun is a smith and weson 1500 in 223. It shoots well under 1 in at 100 yards ever time.

If you can kill with it ANY gun is good.:}
