AR-15 9mm Bolt Assembly Ramped Bottom CMMG Phosphate Coated
CTD has the ramped 9mm bolt carriers for $149.
yea i know that ain't cheap but most places are asking $199 for them if you can find them in stock.
the ramped bolt is very nice as you don't have to use a 9mm hammer.
most ar-15 hammers work very smoothly with the ramped bolt/carrier.
you guys building 9mms sould look into this and those CMMG 9mm lowers--
