I have a RRA service rifle take off barrel. Looks to have been shot little if any. Original owner said less than 100 rounds and was very accurate, he just went ahead and installed a Krieger. I have not shot it. 1/8 twist, M4 ramps, stainless, not threaded. $120 shipped CONUS. I also have the matching bolt, add $50. I accept PayPal FF or add 3.5% for fees or US Postal Money orders. Sorry no trades. Thanks, Paul
