They've been made in 9mm, .38 Super, .30 Luger, AND .22LR... I suspected it was .45, but the add didn't say what it was! I do sometimes ask leading questions in adds in order for the OP to include pertinent information... ;-)
Thanks for the rep. I know and I was just giving you one as well. If I end up getting a rifle with 5r you are more than welcome to see it and shoot it.
that is the truth sir. especially with busse blades. if you wait more than a minute it will be gone and two days later it will be on ebay lol. nice blade man. I can't wait to see the user pics.
