Yea I had visited MarlinOwners.com and checked out a thread asking people opinions on the newest made Marlins. Specifically all opinions, not just bad ones as is normal in their rants forum. And most people seemed to be pretty pleased with the newest (probably in the last year) production Marlins. The 336 seems to have less problems than some of the other models.
So I guess as long as I check the gun over before buying, I should be OK.
Though i may have to stick to a good used one. A NIB Marlin is still kinda pushing my budget. $350ish for a lightly used JM seems like a much nicer price. Especially taking into account some ammo, a set of peep sights and a decent sling.
Thank you for the replies guys.
