The factory open sights on the Marlin 60 are just awful, so I threw a scope on. Then I found I really wasn't enjoying plinking with a scope - too easy, and no good field of view. I decided to go back to iron sights, but there really isn't much in the form of aftermarket sights for the Marlin. Williams Firesights are about it, and while they are better than the stock I don't much care for them. There are a few peep sights that might work, including a Williams receiver mounted peep sight (around $40), but most internet rimfire forums indicated it would constantly loosen and shift it's adjustments under heavy use. Tech Sights ( http://www.tech-sights.com/ ) has a GI style peep sight and replacement AR style front sight available for $69. A bit expensive, but most reviews indicated that it is the cat's azz, solidly mounted and supremely accurate. After some hemming and hawing about a sight that cost 1/2 of what the rifle cost, I went ahead and bit the bullet today. The guy answering the phone was friendly and helpful, and I now feel good about ordering a set. I'll post pics and a review once they arrive in a few days. From the website: Wanna kill these ads?
