    Does anyone know where I can find genuine MilSpec receiver extensions (buffer Tubes) for the M4? I ordered the Vltor rec ext from Brownells and was disappointed to see that they were the right demensions but made from extruded aluminum tubing, not milled! I am looking for the grey colored, milled aluminum, MilSpec Item. Thanks for any info!
