I'm thinking about skipping it and using the regular one I already have on my 243 Win bolt. The rifle is feeding out of AICS magazines, so there doesn't appear to be any reason to shorten the bolt travel.
That's all it does, shorten the bolt throw. A few of those I've ground the "fin" off the extension then flip them 180 one way or the other depending on the cartridge and magazine.
