RE: winchester model 670 A
I took the cheap birch stock off and installed a Winchester synthetic stock (with blind magazine of course). The gun looks great. I will hunt with itnext week after sighting it in. The 670 is a push feed not a controlled feed but I haven't had any problems feeding or ejecting rounds with it. I put a Simmons Aetec 2.5X-10X 44mm scope on it with Millet rings and bases. So far everything looks good.
