I just bought a 453 American in 17 HMR from Wholesale on Thursday...did not come with rings...Burris makes a nice steel set for the rimfires, about $35...my 527 in 221 Fireball came with rings. Have had it a couple years now.....great little gopher gun...40gr VMax's with LilGun powder...15.5 grs....that little detachable mag is great, you can pop it out and top up without taking your eyes off the "patch"......"backwards safety"?...who the he11 uses a safety on a gopher gun?........an empty chamber is the best safety..chamber up when you're ready to fire....besides, your barrel will cool quicker when it's open at both ends....not that barrel heating is a problem with the Fireball......I don't think I've ever engaged the safety.....maybe I should see if it actually works.
When I get around to trying out a 204, pretty good chance it'll be a CZ.....
