Anyone have any real velocity numbers on really short grendel barrels, like 7.5, 8 or 9 inches? Are there any factory offerings by anyone in this size, or am I going to have get one specially made?
I'm looking at building an PDW-style AR15 pistol, and I would like to use the 6.5, if its feasible, over the .300 blk or .223 rem. I know it might be challenge to get on running well versus a .300 blk, but it would be nice not to have to branch into a new caliber if I can avoid it.
