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!

Do you have the spec for the receiver extension? AFAIK the spec calls for forged or impact extruded 7075 aluminum. LMT also sells a 7075 milspec diameter extension.

VLTOR is another producer.
