If enough people want it to make it lucrative, then maybe Bushmaster will make happen. Casted my votes for A2 type profile and 1/7" twist. Having a fast twist rate to stabalize heavier bullits (75-77 grain) while still being able to put ss109 in the black just makes sense to me. I do not plan on using a carbine for light weight varmit bullits however. Those Cavalry Arms C6 mentioned above sound like a winner as well. I would rather have the chrome lined, 4150 steel, nato chamber, milspec quality barrel by Bushmaster than a RRA (no chrome, only 1/9" twist, 4140 steel) or ArmiLite( 1/9" twist, 4140 steel, but chrome lined)
edited to add: sorry no room for pre/post ban
barrel configuration preference. Hopefully soon (2004) this wont be an issue.
