Someone please correct me if I'm wrong here, but the only thing I could think of to building something close to the CSAW would be to get a separate black mcx lower and use the black 11.5 conversion kit upper. Again, its not the 10.5, but I can't think of any other way to get anything as close. Seems like the only way to get black is to buy the 11.5 conversion kit upper as every Spear LT ive seen comes tanodized from the factory.
