I have had an optima for the past 3 or 4 years. I love it. I've hunted with a muzzleloader for over 35 years and this rifle is by far my favorite. I've killed a bunch of deer with it; two so far this year. I is accurate, easy to load and very easy to clean. That is a key point. To clean it, simply remove the breechplug and put the barrel in a bucket of soapy, hot, water. Run a brush through it several times and let it dry.
Enjoy.
