I have a RRA 20 HBAR no-ban chrome-moly barrel for sale. I have put maybe 60 rounds through it. Selling it because I switched to a 16" and free float rail so I do not need this one. Includes handguards, gas tube, delta ring. Here are a couple of pics. $175 includes shipping and insurance. Send me an e-mail, firstname.lastname@example.org, if interested.
