Man I love that stainless 35 without that barrel band Sidespin , didn't know there ever made that that stainless Without" that stupid barrel band .sucker in the stainless . Always wanted one of those 336's in the 30~30 Also without that dang barrel band ...The 336D, as mentioned is indeed ported. The 35SS, a stainless sister version issued in .35 also, is not ported. Neat little rifles. I inded notice a sharper report from the 336D even with radical hearing protection. I also get some flyback from the metal jackets sometime. Eye protection is essential.
